Advantages of geometric sets? and other questions

[pavanabatchu]

I want to know what is the best approach in creating a complex part.
do we have to create more bodies under one body.if ,so why we have to create 4 or 5 bodies under part body.
and when we have to create more geometric sets.
and when we work with surfaces combined with part design,
is it best to use -
wireframe and surface design or
generative shape design workbench.
also,when we have to use positioned sketch.

Many of the topics asked about depend on your companies Standard Procedures and the type of design work that is being done.

Q1. do we have to create more bodies under one body?

Most parts can be modeled in CATIA within a single Body, the PartBody, and do not require inserting additional Bodies. Multiple Bodies (with Boolean Operations) are only required for special, or very complex parts.

Q2. when should we create more geometric sets?

Adding several Geometric Sets can be used to group various wireframe and surface geometries. For example, casting geometry in one set, machining geometry in another set, inspection data and NC data in other sets. Some users like to store all sketches in a seperate Geometric Set for sketches only.

With complex parts, having multiple Geometric Sets makes it easier to work with the CATPart file.

Q3. when we work with surfaces combined with part design, is it best to use wireframe and surface design or
generative shape design workbench?

The Generative Shape Design workbench is better because it contains more tools.

Q4. when we have to use positioned sketch?

As a general rule, always use Postioned Sketches instead of Sliding Sketches. Positioned sketches are locked in place and won't inadvertantly move when modifying the model.
