The basic difference between a standard member and a stiffening member is, that we can not input any internal forces on the stiffening member. This means, that a stiffening member is not a part of your original FEA 1D member analysis model. Basically, we use standard members only if we need to apply load/constrain on them.
To place stiffening member we add a new manufacturing operation:
