For me the properties of the plane come from the first component inserted into this plane, so you had to create the plan of the single component first and not the whole.
In fact, we migrated to EPDM at the beginning of the year.
Our database was not the cleanest because no real management clue file name... So we couldn't ship all the files
I regularly import old files, this is the case on this one.
So I had to first integrate the missing components, then the assembly. of course, not everything went smoothly, I had to redefine some of ASM's constraints.
and there once the 2D is opened, it points to the component and not to the ASM, so I have my overall plan but all the information in the cartridge is that of the component.
A priori the right click worked, surprising because I've done it several times since this morning and it didn't do it.
Thank you for your interventions, I hope the pb is resolved.
