Teachers’ notes

Introduction The Cell phone tutorial will introduce students to the skills and techniques needed to develop design ideas within Pro/ENGINEER Wildfire 3.0. This should be considered as an introductory tutorial exploring the Pro/ENGINEER interface and basic software operations.

Pre-requisites Pro/ENGINEER Wildfire 3.0 Schools Edition or Pro/ENGINEER Wildfire 3.0 Schools Advanced Edition or Pro/ENGINEER Wildfire 3.0 University Plus Edition or Pro/ENGINEER Wildfire 3.0 Student Edition This tutorial contains screen and menu images taken from the Schools Edition so users of other Pro/ENGINEER editions may notice some slight differences. This tutorial has also been based on the use of Pro/ENGINEER start parts & templates. While this tutorial can be used with other Pro/ENGINEER start parts there may be changes required in terms of view orientation, datum plane and coordinate system references etc. This tutorial requires no previous modeling experience in Pro/ENGINEER; however the User should be able to navigate the Pro/ENGINEER Wildfire User Interface. Pro/ENGINEER Wildfire requires the use of a 3 button mouse. If possible a mouse with a combined middle wheel & button can improve User interaction with Pro/ENGINEER Wildfire.

Background: Getting Started The goal of this tutorial is to introduce the student to the Pro/ENGINEER Wildfire 3.0 user interface and to acquaint them with some of the basic operations within the program. This graphic shows the basic interface and indicates the main components of the interface. This is also referred to as the Model Window. As you work through this tutorial you will use many of the commands through these toolbars and the Dashboard. The options in the Feature Creation Toolbar and the Dashboard will vary depending on the operation.

Pro/ENGINEER Wildfire requires the use of a 3 button mouse. If possible a mouse with a combined middle wheel & button can improve User interaction with Pro/ENGINEER Wildfire.



Within Pro/ENGINEER Wildfire 3.0 many of the operations take place in a second window called the Sketch Window.

NOTE: For a more complete description of the features and functions of the icons and program commands, refer to the Pro/ENGINEER Quick Reference Card located at the front of this section.



Aim: In this lesson students will learn about the Pro/ENGINEER graphical user interface (GUI) and begin creating the cell phone.

Learning objectives: By the end of this lesson students should: Be aware of the part creation techniques using Pro/ENGINEER.

Understand the principles of sketch based features and direct features.

Be able to create valid sketch geometry.

Be able to create solid shapes using extrude and revolve features.

Be able to create an assembly using a number of component parts.



NOTE: The screen captures and illustrations in this tutorial include some of the information and instructions that will be required in order to successfully complete this project.

Working with multiple parts 1. Before you begin, let’s look at this project more

closely. The Cell Phone consists of 8 component parts. You will be required to build each of the parts and create the assembly.

2. All of the parts will be created in the cell phone directory. Therefore, make sure that you set your working directory correctly.

Task 1: Set Working Directory NOTE: Check with your instructor in order to get the proper procedures for setting the working directory in your lab.

3. Start Pro/ENGINEER Wildfire. Use the sash

controls to close the browser window. 4. In the Navigator Window (down the left-hand

side of Pro/ENGINEER), browse to the “cell phone” folder.

5. If the Navigator is not displaying Folders left-

click the Folder tab at the top Navigator Window.

6. Right-click the “cell phone” folder, and in the menu that appears select Set Working Directory.

of the centerline and 0.1875 above the TOP Datum (bottom edge of pad)

23. Complete the sketch, return to the dashboard, give the button a depth of 0.22




NOTE: Patterning is easier to understand if you think of it as repeating dimensions rather than repeating features. Even though it is the feature that gets repeated in the pattern, you will define the dimensions in the dashboard. You will indicate the direction in which they will be repeated and enter the number of copies, including the original, to be made.

25. Select the button extrusion in the Model Tree, right-click, select Pattern from the shortcut menu

26. Select the 0.44 dimension 27. Change the value to -0.44, press ENTER (A

positive value would have produces copies to the right of the original button, away from the referenced dimension)

28. In the dashboard, set the number of copies to

3, the original and two additional buttons 29. Black dots will appear to indicate the locations of

the copies 30. In the dashboard, select Click here to add item 31. Select the 0.1875 dimension 32. Change the value to 0.35, press ENTER 33. Set the number of copies for this direction to

edges of the first button (pattern leader) 38. Apply a Round of 0.03 39. Complete the operation 40. The Round will appear in the Model Tree 41. Select the Round from the Model Tree, right-

click, select Pattern 42. Complete the operation 43. The Round will be applied to each of the

buttons in the pattern 44. Save the part

45. Now for the large button 46. Select Extrude, select Placement, Define 47. Select the Front surface of the pad as the

sketching surface 48. When the Sketch window opens, select Sketch

from the Main Menu, select References 49. Select the edge of the upper right button as a

reference. You are actually referencing the vertical surface of the button

50. In order to select the correct entity, place the cursor over the button edge, right-click, and select Pick from list from the shortcut menu

51. Select any one of the surfaces listed. The edge around the entire surface will highlight

52. Close the References dialog 53. Select the centerline tool, snap a vertical

centerline on the right side the referenced edge

54. Create a vertical centerline through the center of the pad



55. Sketch the polygon for the large button

56. Use Add Dimensions to complete the required dimensions as shown below


58. Use Extrude To Surface 59. You will be prompted to select an existing

surface to use as a reference for the button height

60. Select the top of one of the small buttons. 61. The height of the large button will now be

dependent on the height of the smaller buttons.




NOTE: Important read this before proceeding. The design intent is to keep the large buttons vertically spaced to the lower pattern in the same proportion as the lower pattern buttons are vertically spaced to each other. We will use a relational formula to keep the proportion exact. You will also learn how to reference dimensions by their ID numbers (example: d56) rather than their values. To toggle the display between dimension values and ID numbers, use Info>Switch Dimensions. (The dimension ID numbers may be different from the ones shown here.) The dimension ID has a prefix that identifies its dimension type. A dimension in Sketcher will have an s in front of the d, noting it as a Sketcher dimension (example: sd44). Dimensions for the elliptical buttons use the letters Rx and Ry for radius x-direction and radius y-direction. You don’t need the extra prefix letters when entering the dimension IDs in relations. The dimension Ryd8 would just be entered as d8. The relation includes the dimension between the vertical centers of two adjacent small buttons (d273) and the button y-direction radius (d269) as shown in the next figure. It stipulates that the distance between the bottom edge of the large button and the center of the small button below it (d301) is the same as the distance between the edge of a small button and the center of the next one in the vertical direction. That distance is the distance between two button centers, minus the radius of one button. So the expression you’ll enter is:

Distance between large button bottom edge and center of next small button=small button vertical center to center, minus small button y-radius or: D301=d273-d269 (You will use your equivalent dimension IDs)

63. If you have not already done so, Click Info, Switch Dimensions from the Main Toolbar to change the dimensions to ID Numbers.

64. To enter the relation, click Tools, Relations from the Main Toolbar. The Relations Dialog opens



65. Click the large button and then the pattern

that is the small buttons. The dimensions should appear in symbol form.

66. Using the figure shown as a guide, and substituting the symbol names as they appear on your model, enter the following into the Relations dialog box: d59=d33-d11

67. Click OK in the dialog box. The formula now determines the value of d59



68. Changes made to the dimension between the

small buttons will now effect the placement of the large button.

69. Round the edges of the large button 70. Multiple select the four vertical edges (corners)

of the large button 71. Add a Round of 0.11 72. Multiple select a portion of the top and bottom

edges of the button 73. Add a Round of 0.04, it will be automatically

applied to the entire edge. 74. Save the part

75. The large button will now be mirrored 76. From the Model Tree select the large button

extrusion and the rounds 77. Select Edit, Mirror from the Main Menu 78. Select the RIGHT Datum Plane for the Mirror. 79. Complete the operation, save the part



Task 7: Creating the back cover The back cover includes a shell operation, adding a draft angle, creating new datum plane offsets, creating the antenna brace and the screw posts on the floor of the shell.

1. Create a new part named BACK_COVER 2. The basic extrusion should follow these

dimensions: Height = 4.75, Width = 1.75, Depth 0.50.

3. Center the sketch side to side and place the lower edge of the rectangle on the TOP Datum Plane




5. An angled cut has to be made to taper the back side of the phone

6. Select the RIGHT Datum Plane 7. Select Sketch 8. Select Sketch from the Main Toolbar, select

References 9. Select the top edge and the left edge as

References 10. Draw an angled line, change the dimensions to

be as follows: Distance from the left edge to the beginning of the line on the top edge = 0.25, the angle between the left edge and the line = 9.00


12. Select Extrude 13. The sketch is located along the center of the

part 14. The extrusion will go in both directions a total

of 1.75, select Remove Material 15. Complete the operation, save the part

16. Select the two bottom corner edges 17. Right-click, select Round Edges, apply a

round of 0.50 18. Select the two top corner edges 19. Right-click, select Round Edges, apply a

round of 0.75 20. Select the junction between the extrusion and

the cut, apply a round of 4.00 21. Complete the operation, save the part.



NOTE: The Draft feature will taper the back cover on all sides by 10 degrees, from the front to the back. To define a draft, you select the surface to which the draft will be applied, then specify the hinge plane, a draft direction, and a draft angle.

22. Select one segment of the surface to be drafted. Orient the part as shown

23. Select Insert, Draft, the dashboard opens. 24. Open the References slide-up panel. The draft

hinges collector is active. 25. Select the Front surface of the part, this will act

as the hinge reference 26. The draft angle handles appear. The draft

direction arrow should be pointing away from the solid.

27. Drag the handle to 10 degrees, or enter 10 for the depth

28. Click Preview to see the finished draft. 29. Complete the operation, save the part

30. Now the back edges will be rounded. 31. There are ten sections to the back edge.

Because all of the sections form a continuous line, you can use the Shift key to select the chain of the edge

32. Select one of the edge sections, hold the Shift key and select a section that is connected to the first, this will select the entire chain

33. Right-click, select Round Edges, enter 0.15 34. Compete the operation, save the part



35. Now, we will shell the part. 36. Select Shell, enter a thickness of 0.06 37. Rotate the part as shown, select the front

surface 38. Complete the operation, save the part

NOTE: The antenna brace is extruded into the solid from a datum plane offset above the part. When a feature is created using a datum made on the fly, the datum is automatically grouped with the feature in the Model Tree. The datum plane is hidden when the feature is finished and is only displayed when the feature is edited. Use the Thru to Next depth setting to make the extrusion conform to the cover surface.

39. Select Insert, Extrude 40. Select Placement from the dashboard to open

the Placement panel 41. Go to the Main Toolbar, select Insert, Model

Datum, Plane, the Datum Plane properties dialog opens

45. Click on the Resume button in the dashboard



46. Click Sketch and select the new Datum Plane 47. Make sure that the orientation is Left, select

Sketch 48. Create a circle, Diameter = 0.29, center to

FRONT datum = 0.22, center to RIGHT datum = 0.62

49. Complete the sketch 50. Select Extrude, make sure the extrusion arrow

is pointing into the cover 51. Select Extrude to intersect with selected

surface from the dashboard 52. Select the surface that the brace will intersect.

This stop the extrusion at the next surface that it encounters, making it conform to an uneven surface.


54. Add a hole through the antenna brace and rounds the edges.

55. Add a hole centered on the brace axis. Turn on

the Axes if they are not visible 56. Select insert Hole, set the Diameter to 0.13 57. Open Placement, select the Axis of the brace as

the Primary reference, the hole type should be coaxial with the axis as the primary reference

58. Click in the Secondary reference collector to activate it, select the circular surface of the brace as the secondary reference

59. Select to Next as the depth type, the hole will stop at the next surface.




61. Add a 0.03 Round to the top of the brace 62. Add a 0.02 Round to the Bottom edge of the

brace 63. Complete the operation, save the part

Task 8: Adding screw post extrusions to the back cover NOTE: This task will complete the back cover. We will add two screw post extrusions that will be used to screw the halves of the cell phone cover together. You will use a standard-spec type of screw hole in the post, and add rounds to the posts’ intersection with the shell. When you have finished these operations, you will copy and mirror them to the opposite side of the shell. Because the posts sit below the surface of the shell profile, you will make a datum plane below the rim of the shell to use as a sketching plane. The posts will extrude from the new plane down to the floor of the shell, the same way the antenna brace joined the shell.

1. Select one long section of the shell edge, hold the Ctrl key and select the opposite long section, select OK

2. This will place a new datum that we will use to locate the offset datum for the posts.

3. Select Insert, Model Datum, Plane 4. Select the Plane that was just created, make

sure the direction arrow is pointing into the shell, set the offset to 0.06



5. Select the new offset datum plane as the sketching plane, select sketch

6. Select the RIGHT and TOP datum planes as references

7. Create a circle as the bottom post, create a second circle the same size as the top post

8. Dimension the circles as shown. Note that the circles are not the same distance from the center of the shell


10. Select Extrude, make sure the extrusion arrow is

pointing into the shell

11. Select Extrude to next 12. Complete the operation, save the part



NOTE: Add countersunk holes to the posts. Add one hole then copy it to the second post. After this you will mirror the post to the opposite of the shell. They will all be associative. The hole goes through the back of the shell. It is counter bored, so the countersink occurs near the top of the post, as shown. Be sure that the axes are displayed, they will be used as the references for the holes.

13. Select Insert, Hole. Select the axis of the lower post

14. A preview hole is placed concentric to the axis 15. Click the Placement panel. The hole should

show as coaxial, with the hole’s axis as the primary reference.

16. Select the large flat surface on the back of the shell as the secondary reference

17. The hole is now properly referenced.

18. Select the Standard Hole , select a screw size of 2-56

19. Select Through All, select Countersink and Counter bore

20. Select Shape from the dashboard and define the information for the hole as shown.



21. Complete the operation, save the part 22. The four holes need to be associative, that is,

they all update when a change is made to the parent. The best way to do this is to copy the parent feature to another location, in this case, the second post.

23. After the hole is copied to the second post, mirror the two posts, holes and the rounds to the other side of the RIGHT datum plane.

24. To copy a feature, you proceed through a series of prompts is the Menu Manager that let you change dimensions or references for the copied feature. In this case, you will just be copying the hole along the same plane, to a different axis.

25. Select Edit, Feature Operations 26. Select Copy in the Menu Manager 27. In the Copy Feature submenu, highlight New

Refs, Select, and Dependent, and then Done

28. You will be prompted to select the feature to copy

29. Select the Hole from the Model Tree, then OK in the Select box, and Done in the Menu Manager

30. The Menu Manager opens the Group Elements menu, with VAR DIMS highlighted, click Done

31. The WHICH REF menu opens, the surface reference of the parent part is highlighted

32. You are not going to change this reference, select Same

33. The second reference for the hole (axis) is highlighted,

34. Leave Alternate selected, click on the axis of the second post. Select Done.

35. The hole is copied,, and added to the Model Tree as a copied group. Select Done.



36. To copy and mirror the screw posts to the other side of the shell, use the same process that you used to copy the holes on the PC Board

37. In the Model Tree, select the protrusion that makes the two posts, the original hole, the Group for the copied hole, and the Round feature at the base of the posts (this should be one feature)

38. Select Mirror 39. Select the RIGHT Datum Plane as the mirror

plane 40. Complete the operation, save the part 41. This completes the Back Cover



Task 9: Creating the front cover The front cover is similar to the back cover in that it is a shelled protrusion with screw posts extruding from the interior surface. It includes cuts to accept the lens and mounting shelves for the speaker and the microphone parts. The front cover also requires cuts to accommodate the buttons of the keypad. In this case, the easiest way to create the holes in the front cover is to do it at the assembly level. When the keypad and the front cover are part of an assembly, you can create all the required cuts by removing material where interference exists between the two parts. The cutouts are passed back to the part and remain stored with it.

1. Create a new part named FRONT_COVER 2. The basic extrusion should follow these

dimensions: Height = 4.75, Width = 1.75, Depth 0.195.

3. Center the sketch side to side and place the lower edge of the rectangle on the TOP Datum Plane

4. Complete the operation 5. Add two construction datum planes, 6. Select Insert, Model Datum, Plane 7. Select the surface opposite the TOP datum

plane as a reference, the new datum appears in preview

8. Click the direction arrow on the preview datum so it points toward the solid. This datum will be flush with the surface, set the translation value to 0.00, click OK in the Datum Plane dialog



9. To add the second construction datum plane,

select Insert, Model Datum, Plane again 10. Select the datum that you just created as a

reference, the new datum appears in preview 11. Set the translation value to 2.00, click OK in

the Datum Plane dialog 12. The new datum is added 2 units below the first 13. Select the top two corner edges (turn off the

datum planes for clarity)

14. Right-click, select Round Edges, apply a round of 0.75

15. Select the bottom two corner edges, apply a round of 0.50


17. Add the Lens housing extrusion 18. Select Insert, Extrude 19. Select the front surface of the first extrusion as

the sketching plane (this is the surface that is offset from the FRONT Datum Plane) Click Sketch

20. Add the offset construction datum as a reference, close the references dialog

21. Select Sketch, Edge, Use to define the extrusion using existing edges. When the Type dialog opens, click Chain, but don’t close the dialog

22. Click on both sides of the existing extrusion. Pro/E selects the two lines and one of the arcs between them, the upper or lower

23. Use the Choose dialog to make sure that the upper arc is selected

24. Click Next to change the selection, click accept, click OK, click Close in the Type dialog. The chain is marked by the S-shaped chain symbol



25. Place a Center-and-Endpoints arc so that the center point is aligned with the vertical center, and constrain is so the arc is tangent to the construction datum plane reference line

26. Trim the unnecessary lines below the arc points

27. Set the arc radius to 1.94. Because the section’s edges are defined by the underlying edges, and the arc’s center is in line with the vertical centerline, the angle value is enough to define the dimensions of this section.

28. Complete the sketch 29. Extrude to a depth of 0.13 away from the

FRONT Datum Plane 30. Complete the operation, save the part

31. The top of the cover has to have a rounded cut for the earpiece

32. Create the arc shown 33. Use the RIGHT Datum Plane as the sketching

plane 34. Add the Front edge and the first datum plane

that you created as references 35. Use a simple arc to define the section, make

sure that the automatic Tangent constraint symbol (T) appears

36. If the 0.20 dimension does not appear as the weak dimension, use Add Dimension to insert it

37. Enter a value of 1.00 for the arc radius 38. Complete the Sketch 39. Extrude the section, Remove Material, Both

Directions, depth = 1.77 40. Complete the operation, save the part



41. The Draft feature has to be added 42. Select one of the side surfaces of the solid,

select Insert, Draft, the dashboard opens 43. Select the back surface of the solid, the draft

arrow should be pointing away from the solid

44. Enter 10.00 in the dashboard for the draft angle 45. Complete the operation, save the part 46. Round the edges 47. Select the upper edge between the face and the

51. Apply a round of 0.15 to the edge 52. Rotate the solid so the back surface is visible 53. Select the back surface, select Shell 54. Set the Shell thickness to 0.06 55. Complete the operation, save the part



NOTE: The following set of procedures completes the interior of the phone. You will create an opening for the lens, the mounting and holes for the speaker and the microphone. Then you will create a set of four screw posts to join with the ones on the back cover.

56. First we will create the shelf on which the lens mounts. Its dimensions are the same as the lens itself

57. When you created the lens, the section was saved as lens.sec. This saved section is used for the cut.

58. Orient the cover to the Front view using the Saved View List icon

59. Select Insert, Extrude, select the surface that will take the lens cut as the sketching plane, select Sketch

60. Select Sketch, Data from File, File System. In the browser, select the lens.sec file

the bottom arc of the lens section 67. Align the centers of the lens section and the

cover. Select Sketch, Constrain, Co-linear 68. Select the vertical centerline of the lens

section and the vertical centerline of the cover

69. Complete the Sketch 70. Select Extrude, Point the extrusion arrow into

the cover, set the depth to 0.02, select Remove Material Complete the operation, save the part



NOTE: Use an existing edge as the basis for the dimensions of the lens cutout

71. Select the floor of the lens cut as the sketching plane, select Sketch

72. Select Offset from edge from the Edge Tool flyout. In the Type dialog, select Loop (Don’t close the dialog)

73. Select the shelf outline. The direction of the offset is determined by an arrow

74. You are prompted for an offset value. Because you want the offset inside the shelf outline, enter a value of -0.03.

75. Close the Type dialog, the outline for the cutout section is created as an offset

76. Complete the sketch 77. Select Extrude, make sure the arrow points into

the cover, select Remove Material, Through All

78. Complete the operation, save the part 79. Select the four inside corners of the shelf cut,

81. Select the flat area surrounding the lens cutout as the sketching plane

82. Add the top most edge of the cover as a reference line, add a horizontal centerline 0.40 below the top reference line

83. Create a circle centered on the intersection of the two centerlines, set the diameter to 0.04

84. Create a concentric circle, set the diameter to 0.12, convert this circle to a construction line

85. Create four additional circles at the intersection of the construction circle and the centerlines, when the R constraint symbols appears, the radius of the new circle is the same as the radius of the center circle


87. Extrude the holes, remove material, the holes go through the cover

88. Save the part before proceeding



NOTE: Create the earpiece holder as a thin extrusion. A thin extrusion is hollow, which precludes combining a solid and a cut to define a shape, for example, a cylinder. You give a thin extrusion a wall thickness value when you define the section. Once again you will be placing a feature through a surface that is not level, in this case, the curved upper surface of the front cover. The solution is to extrude it down to the floor of the cover from an offset datum plane, as shown below. The depth setting of through to next will make the collar conform to the surface when the two intersect.

89. Select Insert, Extrude. Click Insert, Model Datum, Plane to create a datum to be used as the sketching plane. Use the upper surface of the shell for the offset reference and offset the new datum plane by -0.10 from the reference surface.

90. Zoom in on the ear hole pattern, select the center hole, create a Concentric Circle, set the diameter to 0.28, this will be the inside diameter. Complete the sketch

91. Set to extrude to intersect with selected surface , make sure the arrow points into the

cover

92. Select the Thicken Sketch icon enter 0.03 as the wall thickness

93. Click the Direction icon , make sure that the sketched dimension is the inside diameter.

94. The icon toggles the thickness to the inside of the section, the outside of the section, or the center of the section. Watch the preview as you toggle, the feature will be at it’s largest when the section is used as the inside diameter.




96. The earpiece holder now needs to have a shelf

cut and a round applied 97. Use the top surface of the earpiece holder as

the sketch plane 98. Create a shelf using a concentric circle, set the

diameter to 0.32 and the height of the shelf to 0.05

99. Create a round at the seam between the holder and the shell with a radius of 0.03

100. Save the part

101. Add the microphone cut and holder 102. Use the floor surface of the shell as the

sketching plane and lowest edge of the part as a reference.

103. Create a sketch as shown 0.29 above the lowest edge, 0.17 from outside to outside, set the radius of the arcs to 0.02

104. Extrude the sketch, add a round of 0.02 on the front edge of the slot

105. Create a datum plane using the upper surface of the part, offset the plane -0.03

106. Create a thin extrusion with a wall thickenss of 0.03, extrude this down from the plane to the surface of the shell

107. Place a vertical centerline through the Right datum, select one of the arcs and place a horizontal centerline through the center of the arc

108. Create a rectangle make sure the “> <” equidistant constraint symbols appear in both directions

109. Set the dimensions to 0.40 wide, 0.30 high



110. Extrude the sketch to the surface of the shell 111. Set the wall thickness to 0.03 112. Toggle the direction until the section is at it’s

largest 113. Complete the operation 114. Add a 0.01 round to the base of the

microphone holder 115. Save the part

NOTE: We will now create the four screw posts. The screw post is made up of three features. The first is a simple round protrusion from a datum plane to the surface of the shell. Use the Front datum plane for this operation. Create two posts an upper and a lower as one feature, The second feature is a pin used to locate align the front and back covers. The third feature is a hole.

116. Use the Front datum as the sketching plane 117. Sketch two circles, dimension as shown 118. Complete the sketch, extrude the posts to the

surface of the shell



119. Sketch the pin feature using the top surface

of the posts as the sketching plane 120. The pins protrude out from the surface of the

posts 121. Create concentric circles 0.125 in diameter,

set the depth to 0.04 122. Complete the operation

123. Next add the holes to insert coaxial holes in

each post. 124. The holes use the axis of the pins as the first

reference and the surface of the pin as the second reference

125. The holes are standard M2.2X.45 holes with ISO threading. The screw depth is 0.21

126. Add 0.02 rounds to the juncture between the posts and the shell

127. Select all of the features that make up the posts

128. Mirror these items about the Right datum 129. Save the part.

NOTE: This completes all of the parts needed for the assembly. Do not be concerned about the cutouts in the front cover for the keypad, these cuts will be made for you during the assembly operation.



Task 10: Assembling the Cell Phone You’ll start assembling the cell phone by placing a “base component” into an empty assembly file. You will then use placement constraints to ass each subsequent part and orient it to the base component. These constraints determine whether surfaces and edges are aligned, mated, or offset, and by what values or limits. Assembly Constraints Constraints in an assembly are similar to those used in Sketcher in that there must be enough of them to complete the placement of a part in relation to another part in 3D. You must establish references in two directions, define a surface or edge relationship (mate or align with an offset if required), and enter values for references. When enough constraints are on a part in an assembly, the part is fully constrained. A part can be added to an assembly without it being fully constrained. In this case, the part is considered packaged. You can interactively import, place, and constrain parts to build an assembly object by object. You can also use automatically determined placement constraints to speed up the process. We will use both methods for assembling the cell phone. When you start an assembly, you must first determine which part will be the base component. All of the subsequent components that you assemble reference this component either directly or indirectly. Therefore, you should always use a part that you are not likely to remove from the assembly. For this assembly we will use the Front Cover as the base component.

1. Begin by creating a new assembly file 2. Click Insert, Component, Assemble. The Open

dialog appears, select front_cover.prt 3. The front cover appears and the Component

Placement dashboard opens 4. Click the Default constraint set from the

Automatic constraint set list to assemble the front cover in the default position. This will align the part coordinate system with the assembly coordinate system.

5. Accept and save the assembly.

you can begin to add other parts to the assembly

7. Add the Lens to the assembly 8. Click Insert, Component, Assemble 9. Select the lens.prt from the file list

10. Click the Separate Window icon from the right side of the dashboard.

11. The part will appear magnified in it’s own window

12. Select the bottom surface of the lens, an automatic constraint it applied

13. Select the surface in the cutout on which the lens will sit. The part is partially constrained.

14. Click New Constraint in the Placement panel 15. Select Insert from the Constraint Type list 16. Select the bottom edge of the lens and the

bottom cutout surface

17. The lens is inserted and mated to the front cover 18. Placement status is Fully Constrained. 19. Complete the operation, save the part



20. Add the Speaker to the assembly 21. The front surface of the speaker has to be

mated into the earpiece holder, it sits on the shelf in the holder. The offset is 0.0

22. Add a New Constraint

23. The second constraint will be the side surface of the speaker and the inside wall of the holder, mate these two surfaces

24. Status is Fully Constrained 25. Complete the operation, save the part

26. Next add the microphone 27. It will require three constraints 28. Select the front surface of the microphone and

the floor of the shell as the first set of constraints

29. Select the long side of the microphone and the corresponding inside housing wall as the second set

30. Select the short side of the microphone and the corresponding housing wall as the final set

31. Use the Mate and Insert constraints to assemble the PC Board to the Base Component

32. Mate the inside surface of one of the holes in the PC Board with the outside surface of the corresponding screw post pin

33. Align the front surface (with the datum curve) of the PC Board with the shelf located around one of the screw posts on the front cover




NOTE: The Keypad is the only part that is not assembled directly to the base component. You will hide the front cover in order to provide a clear view of the PC Board so the selections will be easier. When you add a component to an assembly, you may not know where that part fits best, or you might not want to locate it relative to other geometry. You can leave such a component either partially constrained or unconstrained. An unconstrained componet is called a packaged component.

35. Begin by selecting the front_cover.prt from the Model Tree. Right-click and select Hide

36. Add the Keypad to the assembly 37. Select the PC Board surface between the datum

boundaries as the assembly reference 38. Select Mate as the Constraint Type 39. Select the back of the Keypad 40. For the next set of constraints, select the Right

datum planes on the PC Board and the Keypad. Make sure the constraint type is Align and the offset is Coincident.

Board and the top edge surface of the keypad 53. The Placement Status is Fully Constrained. 54. Complete the operation, save the part



NOTE: The Keypad is fully constrained to the PC Board. Now we can unhide the Front Cover. An interference occurs after you unhide the Front Cover, because the height of the keypad’s buttons exceeds the depth of the Front Cover. Although the buttons appear to protrude through the Front Cover, you must cut out the keypad button holes. Using the assembly to cut the holes lets you modify the Front Cover using the dimensions of the Keypad, without opening either part file. The holes will be passed back to the Front Cover part as an assembly feature.

55. Select front_cover.prt from the Model Tree, Right-click, select Unhide

56. Click Edit, Component Operations, Cut Out 57. Select the Front Cover as the part for the cut
