CATIA V5 - Functional Molded Part modeling

The objective of functional modeling is to enable product designers to focus on the functional goals and design constraints of their product. Capturing this information in the product model provides the information from which geometric form can be derived through the combination of behavioral features and a minimum of geometric construction. The end result is a significant reduction in the effort required to generate the 3D model by allowing more time for designers to focus on engineering issues, exploring alternative design approaches, and optimizing their design

IronCAD - How to add geometry to existing drawings

Bring in dwg or dxf and merge them into the same file. Simple but an effective way to bring geometry together.

IronCAD - How to Spin Revolve a part

Use the spinning method to create a 3D shape or surface by rotating a 2D profile/face around an axis. For example, when you create a 2D cross-section of a right triangle, it is rotated to create a 3D cone.

Because the cross-section spins around an axis, the resulting 3D shape or surface always has a circular nature and must follow a straight path around the axis.
