PrefaceCATIA - Product Functional Definition describes the functional systems of a product to be designed and visualizes them in a schematic-like viewer. This application also manages variants for the functional systems. Moreover, it enables to create links between the functional systems and CATIA product items, thus allowing full functional and physical definition in V5. Finally, scripts can be created from the functional view in order to generate 3D data.

Description of the functional systems of a productThe user identifies the functional objects involved in his product (seen as a system) and the interactions between them. The system is presented as a graph, where the objects are displayed as nodes and the interactions as arcs. This leads to a graphic presentation of sentences. Thus, the semantic view of the product is defined prior to the other product design stages (preliminary and detailed).

Decomposition of the functional definition across several documentsThis approach is similar to the Product - Subproduct decomposition (Insert New, Insert Existing, ...). The parameters of the subsystems, that can be reused on a higher level of the system, can be published. This functionality is useful in case of large systems.

Visualization of the functional systems in a schematic-like viewerThe schematic-like viewer has the UML (Unified Modeling Language look) look. The user can spread graph elements to produce a better 2D layout and allow easy reading a/o analysis of the system model.

Management of variants for the functional systemsTo help the brainstorming on next generation systems and to start alternative studies, the user can keep the old design as a basis.

Creation of links between functional systems and CATIA product itemsThe user can define several associations attached to a functional entity. An association is made of several links to PPR (Process-Product-Resource) items of any kind: product, part, sketch, wireframe element in a sketch, etc. This enables to regroup the links to PPR items attached to a functional entity according to a given design stage (2D skeleton, rough design, preliminary design, detailed design, etc). Consequently, more flexibility and more accuracy are given to the user, who can fully define functionally and physically a product in CATIA V5.

Management of scripts The user can manage scripts from the functional view in order to generate 3D data. A functional entity can contain different scripts adapted to different design stages. This enables to break up the different design stages in different scripts, and thus gives more flexibility to the user.

Using this GuideConventions


Using this GuideThis User's Guide is intended to help users become quickly familiar and efficient with the CATIA Product Function Design application. Before reading it, users should be familiar with the basic CATIA Version 5 concepts, such as the document windows, standard toolbars and menus.

To get the most out of this guide, it is highly recommended to start reading and performing the tasks described in the step-by-step tutorial, known as the "Getting Started" section and reading the Workbench Description to find his way around the Knowledge Advisor Workbench.

This User's Guide is organized into the following sections:

● Preface: A short introduction to the product.

● Getting Started: A step-by-step tutorial intended to provide the user with an overview

of the product functions.

● User Tasks: A presentation of the product functions.

● Workbench Description: A presentation of the user interface.

● Customizing: A description of the menu item and toolbar customization.


What's new?

No enhancements in this release.


Getting StartedCreating and Editing a ComponentCreating a Graph from a SampleCreating and Moving an Action

Like for most CATIA features, you:

● Delete a component or an action by using the Delete command from the contextual menu.

● Edit a component or an action by double-clicking it in the tree or in the geometry or graph area, or by using the edition command from the contextual menu.


Creating and Editing a Component

This task explains how to create and edit a component.

1. In the General tab of the

Tools->Options->Knowledgeware->Product Functional Definition dialog

box, check Empty in Document contents at creation and ASO in Tree display and

click OK.

2. In the standard tool bar, select the

Start->Knowledgeware->Product Functional Definition command. A simple tree

with the OBJECTS, ACTIONS, VARIANTS, and GROUPS OF ACTIONS is displayed.

3. Click the icon then click in the geometry area. The Object.1 box is displayed.

4. If need be, resize the object by using the or icon in the standard toolbar or

drag (left mouse button).

5. Double-click Object.1

in the tree (you must

expand the OBJECTS

node), or in the graph

area. The Edit

Functional Object

edition box is

displayed.

If need be, modify the

object name.

Another way to edit a

component is to right-

click it, and select

Object.1 object-


>Definition.

6. Repeat the same

interactions to create

another object

(Object.2).

Your CATSystem file is

created.


Creating a Graph from a Sample

You can construct a graph:

● From scratch. To do so, see Creating and Editing a Component and Creating and Moving an Action.

● Use a sample provided as an option at the document creation.

This task explains how to construct a simple graph from a sample. The CATSystem document created can be re-used in the User Tasks.

1. In the Tools->Options->Knowledgeware->Product Functional Definition dialog

box, check the options below and click OK:

a) Sample Elements in Document contents at creation

b) ASO in Tree display

2. In the standard tool bar, select the

Start->Knowledgeware->Product Functional Definition command. A graph

similar to the one below is displayed:

3. Double-click the Object.2 object, and rename it in Medicine. Repeat the same

operation to rename Object.1 in Tissue, Object.3 in Piston and Object.4 in Finger.

4. Select the Useful Action action, and delete it by using the Delete command from the

contextual menu.

5. Create the presses and moves useful actions as well as the saturates harmful


action. To do this, see Creating and Moving an Action.

6. Save the created document. Note that a document created with Product Function

Definition has the .CATSystem extension.


Creating and Moving an Action

This task explains how to create and move an action.

1. Open the CATSystem created in Creating a Graph from a Sample.

2. Click the icon, then select the subject component (Medicine for example or its

renamed version), and click the Tissue object. The Action.1 is added to the subject

component. Rename this action to "saturates".

3. Repeat the step above for the other

objects contained in the CATSystem

file. The result should be identical to

the graphic opposite.

To move an action as a whole element and detach it completely from its initial subject and object, select the arrow representing the action right in the middle then drag it. To move either extremity of an action, select the green spot at the extremity of the action that you want to move and drag it to the component to be attached.

product. The Container object can be selected from the tree or from the graph.

4. Click the icon, the following window opens, then proceed as follows:


❍ Under New association, indicate

the name of the association

(SyringeContainer in this example),

then click Create.

SyringeContainer is displayed in

the Existing associations field.

❍ Under Filter, select Part in the

scrolling list.

❍ Select the SyringeContainer in the

.CATProduct, and click Close. The

part is now associated to the

.CATSystem (an icon is added to

the Container object in the

.CATSystem).

(Click the graphic opposite to enlarge

it.)

5. Repeat the same operation with the Piston object.


Linking a Script to a Component
