Hello,

I’m working in sequential mode with a nonsequential component, which is a CAD part (stp). It’s a quite complex part which I exploded into 13 parts. When I change something (like assigning a material or scaling a part) the program freezes and it takes approx.. 2 minutes loading until I can do anything again, although I disabled the auto-update of all windows. When I update the shaded model the whole program freezes and around 10 minutes later it finishes loading. 
I already deleted all unneccessary parts and neither the working memory nor the cpu are at full capacity. 

Does anyone have any ideas on what I could do to be able to work smoothly (or even just a little more smoothly) with complex cad files?

Thanks in advance for any help!
