Does anybody have R12 layout file saved and willing to share?
I really like the R12 modeling layout. R13 doesn’t have one. If some one willing to share it with me, I can simply open it ans asve it as a custom layout.
If you have a copy of R12 you can simply copy the layout files.
The danger of doing this is that any features that have changed or that have been added may not be compatible.
This doesn’t break anything, but you will still want to invest sometime in making sure you are not losing access to anything new that you still want.
