Creating Curved Beams and Merging Tangent Members
You can create curved beams from primary and secondary members in a structure system. Curved members behave the same way as linear members where you can add secondary members between them.
If you select a 3D curve or spline as a reference, the member can only pierce through the center of the profile. Also, in some scenarios, you cannot sweep members with 2D or 3D splines because of their curvature and radius.
You can also merge multiple members that are tangent to each other into a single member with the Merge Tangent Members option and add secondary members between merged members.
