It's possible to save by default, the columns configuration of the Simplify Representation windows
View Manager > Simp Rep > Redefine > Settings > Columns > More...
please ask PTC Support and let us know...
The PTC Support does not have a solution to define the columns by default in the Simpify Representation windows.
It was at the request of the PTC Helpdesk that I opened this post.
Please, vote for this post...
It would also be interesting in the "Shrinkwrap" too
Please post an idea
