When to use a stiffening member?

The fundamental difference between a standard member and a stiffening member is that we can not input any internal forces and supports on the stiffening members. We use standard members only if we need to apply load/constraint on them. 

A stiffening member is not part of the original FEA 1D member analysis model; it only fills in the joint's missing parts. Another feature of a stiffening member, contrary to a standard member, is that you can have it at any length you need.

To place a stiffening member, we added a new manufacturing operation:

Please have a look at the following typical examples when we use Stiffening members:

The summary of the usage of this operation and the procedure to create an example with a stiffening member can be seen in the following video.
