21) What is VDirection?

A) The direction that is parallel to the vertical axis is referred to as vertical direction. The VDirection is mostly used to constrain a sketch.

22) What is the need of surface modeling?

A) The product and industrial designers these days are giving importance to product styling and providing a unique shape to components. Generally, this is done to make sure that the product looks attractive and presentable to the customer. The shape of products are managed using the surface modeling techniques. Surface models are three-dimensional models
with no thickness and unlike solid models, they do not have mass properties.

23) How does CATIA V5 helps in surface modeling?

A) CATIA V5 provides a number of surface modeling tools to create complex three-dimensional surface models. Various workbenches in CATIA V5 with surface creation tools are:

  1. Wireframe and Surface Design.
  2. Generative Shape Design.
  3. FreeStyle.

24) What is ASSEMBLY MODELING?

A) Assembly modeling is the process of creating designs that consist of two or more components assembled together at their respective work positions. The components are brought together and assembled in Assembly Design workbench by applying suitable parametric assembly constraints to them.

25) How many types of Assembly Design Approaches are there in CATIA?

A) In CATIA you can create assembly models by adopting two types of approaches. The first design approach is the bottom-up approach, and the second one is the top-down approach.

26) Can you explain Bottom-up Assembly approach?

A) The bottom-up assembly is the most preferred approach for creating assembly models. In this of approach, the components are created in the Part Design workbench as (.CATPart) file. Then the product (.CATProduct) file is started and all the previously created components are inserted and placed in it using the tools provided in the Assembly Design workbench.
After inserting each component, constraints are applied to position them properly in the 3D space with respect to other components.

Advanced CATIA Interview Questions For Experienced

27) Can you explain about Top-down Assembly approach?

A) In the top-down assembly design approach, components are created inside the Assembly Design workbench. Therefore, there is no need to create separate part files of the components.

This design approach is completely different from the bottom-up design approach. Here you have to start the product file first and then, one by one, create all components. Note that even though the components are created inside the product file, they are saved as individual part files and can be opened separately later.

28) What is the purpose of the ENOVIA and CATIA Solutions?

ENOVIA V5 VPM and CATIA Solutions allow customers to implement their digital enterprise, thus creating and simulating the entire product life cycle from initial concept to product in service.

29) What Are Database Objects?

A) Database objects are the data structures implemented to support the ENOVIA V5 database.

Checking this option:

creates tablespaces (or uses existing tablespaces) creates data structures ( application tables, indexes and views) using the DDL files installed with the code; the role of these data structures is to manage data persistency and object mapping sets up privileges for accessing the data structures
in all database domains, sets up (inserts) CDM STEP data required for domain management (mapping of domain objects) creates the dictionary owner and ENOVIA Administrator in the database.

30) What Are Startup Data?

A) Once the data structures have been created, the installation inserts startup data into certain database application domains.

Checking this option:

sets up domain administration

sets up a default people and organization (P&O) implementation comprising a root organization (ADMIN), a default role used for logging onto ENOVIAV5VPM (VPMADMIN), and an administrator creates default security management: privileges (functional access control), masks (data entity & attribute access control) and processes imports lifecycle graphs.

31) Can you tell me some basic commands in CATIA?

A) When it is required to make a simple solid component, we usually go to Part Design workbench. Important commands in this workbench include PAD, POCKET, SHAFT, GROOVE, RIB and SLOT.

32) Explain the PAD command in CATIA?

A) In most CAD software, the equivalent of this is called EXTRUDE, but in CATIA we call it PAD. PAD command adds material in the third direction, a direction other than the sketch. The cube below was made using the PAD command.

33) Explain the POCKET command?

A) In CATIA,The POCKET command is somehow the opposite of PAD command. It simply helps remove geometry belonging to an already create part.

34) What is SHAFT command in CATIA?

A) Similar to REVOLVE command in other CAD software, the SHAFT command is mostly used to make shaft like parts. It requires an axis, around which the sketch will be revolved.

35) What is GROOVE command in CATIA?

A} As said earlier, there is another command in CATIA to subtract geometry from shaft like components, called GROOVE. This command allows you to remove material by revolving a sketch.

36) What is RIB command in CATIA?

A) The command which is usually known as SWEEP is called RIB in CATIA. It adds material along a guide curve (which can be a straight line, arc or may be a spline). RID is used to make components like springs, pipes etc.

37) What is SLOT command in CATIA?

A) Slot command removes the material along a guide curve.
