Parent-Child Which parent-child relationships work the best? Which parent-child relationships should be avoided? As mentioned earlier, parent-child Relationships relationships are established when selecting the sketch support, as well as all other references throughout the creation of a feature e. Depth Options Which limit type should be used to create features?

The selection of the limit type affects the feature. Always consider the consequences if additional features are added or if other dimensions in the model are modified.

Remember that some depth options result in parent-child relationships e. Formulas are user-defined mathematical equations used to capture and control design intent in a model.

Feature Order Which feature order best captures the design intent? The feature order of a model is important. For example, should a hole be placed before or after a Shell feature? Consider this type of question from the beginning to the end of the modeling process.

Use the specification tree to easily review the feature order at any time during model creation. Multi-body Typically, all of the features that you create are added to the PartBody within the specification tree. This linear tree structure is acceptable for models with a low feature count or simple geometry.

This enables you to structure your model based on your design intent. An important reason for creating multiple bodies is to be able to use the Boolean commands. The ability to combine feature-based modeling with boolean operations Operations permits the creation of robust geometry.

Working with various bodies within a single part file provides flexibility in design scenarios, promotes concurrent engineering, and enables the display and manipulation of multiple model states. CATIA offers tools for manipulating the design when a change is required. They are described in Table 1—1.

The Feature Definition, Table 1—1 Edit Parameters, Reorder, and Define in Option Description Work Object options can also be accessed by Feature Attributes used to create a feature can be modified by selecting the geometry in Definition double-clicking on the feature in the specification tree.

Sketch A section can be edited directly in the model. The Feature Definition Definition dialog box does not need to be opened. Expand the feature in the specification tree and double-click on the sketch. Edit Dimensions that are associated with a specific feature Parameters can be modified.

Reorder The feature order can be reordered for any number of features in the model. Define in Features can be inserted into the specification tree after Work Object the feature is selected. A proficient CATIA V5 user should be able to create robust models that enable design changes to be made quickly and easily, resulting in predictable changes throughout the model.

You will create Pads, Holes, Pockets, and Drafts. The completed model is shown in Figure 1—2. Figure 1—3 The part will be molded. To ease the process of removing the part from the mold, apply a [0. As with every modeling process, you should strive to use the simplest, but most effective methods of capturing design intent. A proficient CATIA V5 user can create robust models that enable design changes to be made quickly and easily, resulting in predicable changes throughout the model.

Considerations Note that relations formulas cannot be used. The surface of the flange and the end of this pipe segment must remain co-planar. The outside diameter of both flanges are the same.

The pipe segment and flange outside diameters must automatically update if the inside diameter of the pipe is changed. Figure 1—6 When you have completed the Pipe model, flex it by modifying the inside diameter of the pipe from 30 to [40].

The model updates, as shown in Figure 1—7. Figure 1—7 A step-by-step solution for this exercise can be found in Appendix C. The base geometry has been created for you, as well as the sketch that defines the cooling fin geometry. Use the Sketch Analysis tool to solve the problem s with the sketch. This tutorials includes an introduction of the main features in the 3D design software package Catia V5. Beside the basic tools of 3D design, a number of exercises and examples point to different construction strategies in several applications.

In addition to the primary functions, methods for the generation of solid components and assemblings are explained and executed by use of different examples. Get service packs, hotfixes, and updates.

It adds material along a guide curve. RIB is used to make components like springs, pipes etc. SLOT removes the material along a guide curve.

Here is an example of slot. This ensures that the cross section will be uniform throughout. Assembly environment is used to provide mating to two or more part models to from complete assembly.

Drafting is a process of generating 2D machine drawing for the 3D part models to send it to the manufacturer's. The Sketcher workbench contains the following standard workbench specific toolbars. Step 3: Part Design Module Part design environment is used to create 3D models from the basic 2D sketches created in sketcher environment.

Step 4: Assembly Module Assembly environment is used to provide mating to two or more part models to from complete assembly We have two approaches in assembly Top -down approachBottom -up approach entire design structure will be created in product environment in Top - down approach whereas in bottom - up parts will be created separately and will be mated using mating or constraint tools. Step 5: Drafting Module Drafting is a process of generating 2D machine drawing for the 3D part models to send it to the manufacturer's.

Catia drafting is of two types 1. Interactive Drafting 2. Generative Drafting.
