    Pro/Engineer is the software product of PTC (Parametric Technology corporation)

    its initial versions were Pro/E 1, 2... up to 17. Later Pro/E launched sequentially

    versions as Pro/Engineer 2000; 2000i, 2000i;2001, Wildfire 1.0; Wildfire 2.0,

    Wildfire 3.0; Wildfire 4.0; and Wildfire 5.0. In 2011, PTC rebranded Pro/Engineer

    as Creo Parametric. The current version of the software is 1.0

    Created by Dr. Samuel P. Geisberg in the mid-1980s, Pro/ENGINEER was the

    industry's first successful rule-based constraint (sometimes called "parametric" or

    "variational") 3D CAD modeling system. The parametric modelingapproach uses

    parameters, dimensions, features, and relationships to capture intended product

    behavior and create a recipe which enables design automation and the optimization

    of design and product development processes. This design approach is used by

    companies whose product strategy is family-based or platform-driven, where a

    prescriptive design strategy is fundamental to the success of the design process by

    embedding engineering constraints and relationships to quickly optimize the design,

    or where the resulting geometry may be complex or based upon equations. CreoElements/Pro provides a complete set of design, analysis and manufacturing

    capabilities on one, integral, scalable platform. These required capabilities include

    Solid Modeling, Surfacing, Rendering, Data Interoperability, Routed Systems

    Design, Simulation, Tolerance Analysis, and NC and Tooling Design.

    Modules in pro/e

    There are three basic Pro/ENGINEER design steps from conception to completion:

    Part creation

    Assembly creation

    Drawing creation

    Each design step is treated as a separate Pro/ENGINEER mode, with its own

    characteristics, file extensions, and relations with the other modes. All information

    dimensions, tolerances, and relational formulasare passed from one mode to the nextbidirectionally. This means that if you change your design at any mode level, the change is

    automatically reflected at all mode levels. If you plan ahead and use the associative features

    correctly, you can save significant time in the design and engineering process.

    Part Mode: The Dashboard and Sketcher

    In Part Mode, you create part files (.prt), the separate components that are joined

    together in an assembly file (.asm). Part mode lets you create and edit the features

    the extrusions, cuts, blends, and roundsthat comprise each part being modeled.

    Most features start with a two dimensional outline, or section. When the section is

    defined, you assign a third dimension value to it in order to make it a 3D shape. You

    create the 2D section in a tool called Sketcher. As the name implies, Sketcher lets

    you roughly draw the section with lines, angles, or arcs, and then input the precise

    dimensional values later.

    You use an interface called the dashboard to create and edit 3D feature geometry.

    The dashboard presents feature-specific fields for input as you switch from feature

    to feature. Once a 3D feature is created, it can be edited directly in the graphics


    Antenna tip in Sketcher and 3D mode

    Assembly Mode

    After you have created the parts, you create an empty assembly file for the model,

    then assemble the individual parts within it, assigning the positions the parts will

    occupy in the final product. You can also define exploded views to better examine or

    display part relationships.

    In a slightly more advanced scenario, you would start the model as an assembly and

    create each part (and part file) from what is called a skeleton part. This is the key

    to top-down design, where an edit to one part can automatically affect the parts to

    which it is joined. You can also associate one part to another part in an ordinary

    assembly using assembly relationsthese will retain associativity between dimensions as theychange.

    In addition, with model analysis tools, you can measure an assembly's mass

    properties and volume to determine its overall weight, center of gravity, and inertia.

    Determining interference between components throughout the entire assembly is

    also possible

    Drawing Mode

    Drawing mode lets you create finished, precise mechanical drawings of the design,

    based directly on the dimensions recorded in the 3D part and assembly files. In fact,

    it is not necessary to add dimensions to objects as you may have done in other

    programs. Instead, in Pro/ENGINEER you selectively show and hide dimensions

    that have been passed from the 3D models.

    Any information objectsdimensions, notes, surface notes, geometric tolerances,

    cross sections, and so onthat have been created for the 3D model can be passed to

    the drawing mode. When these objects are passed from the 3D model, they remain

    associated, and may be edited to affect the 3D model from within the drawing.

    Basic feature/tools

    Creating Files

    When you use File > New to start a new file, you are prompted to select a file type,

    and a subtype if one is necessary.

    When you click OK, the new file opens and the default datum planes appear in the

    main window. The menus and options are configured for the selected type.

    Saving, Backing Up, and File Iterations

    Use File > Save to save changes. Use Save a Copy to save the file to a different name.

    Whenever you use the Save command, a new version of the file is created and a

    numerical file extension is appended to note the version, for example

    front_cover.prt.1, front_cover.prt.2, and so on. These iterations are created so you

    will always have a previousversion to return to in case something fails in the current

    file. When you use File > Open to open a file, the file browser displays the latest

    versions without the iteration numbers.

    To show version numbers in the Open dialog box, click the Commands and Settings

    icon and then click All Versions from the menu. You can then open whichever

    iteration you want.

    To save a file to a different name, format, or location use File > Save a Copy. Unlike

    a conventional Windows Save As command, Save a Copy leaves the original file

    open and active after the save operation.

    If you don't want to store the iterations in your working directory you can use File >

    Backup to specify an alternate directory for the iterations. The first iteration in a

    backup directory starts at 1, regardless of the number of iterations in the working

    Deleting Files

    Use File > Delete to remove files from the disk permanently. You can clear old

    versions only, leaving the latest version intact, or you can clear all versions.

    Use File > Delete > Old Versions to clear the directory of all but the most recent


    Solid Display Options

    As your model becomes larger and more complex, you will switch from solid to

    wireframe display to help in selection and to improve computer performance. The

    two main display modes are shaded (solid) and lined. There are three types of lined

    display. Each shows the outlines of the model in increased detail.
