When I place Content Center parts or build Frame Generated parts, I am often frustrated with having to
Redefine Sketches, update Bolted Connections, edit Constraints, etc. if their lengths change as they often do.
My solution with Content Center parts is to open them, after placing them in an assembly, and edit the body to be built Symmetrically. Obviously, this takes time to do but far less time than having to Redefine Sketches, etc., but it still takes time.
This would likely work well with Frame-Generated Parts to avoid having to edit Miters, Trim/Extends, Notches, etc.
Everyone with whom I work has found this to be an issue as well.
Please consider adding this as an Application Option in the future. That would be super helpful.
Thanks,
