Thanks Vaquer99,
you talked about a very important point. Restrictions and I would add the nests.
From what I’ve seen not only in ZW3D, the fewer constrains, and the fewer subcomponents there are within a much better part.
The philosophy is to create assemblies with few parts.
Usually in large sets when I have everything checked, I remove the constraints and fix everything.
Another aspect is to avoid using embedded images on surfaces, as they slow down a lot.
I hope that little by little, they will improve the management of large sets.
