CAD Export Rules

Using SimScale
1

HI

I’m just beginner of simscale and some trouble makes me crazy these days

I definetly make my CAD ( there is three parts in my CAD ) but when i export my CAD as stl ( or iges) and if i upload my CAD on simscale
It becomes one stuff ( there is no more part anymore)

So is there any rules when export CAD files ?
I’m using NX version 6

Hi @Reynnoldsnumber, this is a common problem with STL. You can export as a .step file and this will preserve faces and solids, however, a better workaround is to export each part individually then merge them as described in this workshop:

Good luck,
Darren
