Complex surfaces

I am modelling an injection moulded part with lots of draft and some reasonably complex surfaces, but nothing over the top.. Model was getting very slow so I got it to a stage where I had all the outside surfaces as a solid model and could shell the part.
I thought to speed up the process I would export a step model and import it back into a new part to finish off the rest of the part. Dumb solid effectively
When I import the STEP model back into Onshape I can no longer shell it, even though I could before I exported the same geometry.

    Hi @Agersens if you must do that use Parasolid. How many features are in the part? You could also derive it into another Part Studio or link it into another Document.

    Hi Ageresens, I am hoping what @NeilCooke suggested has helped solve the shelling problem.

    However, this shouldn't be an issue that you have to try and work around.  Have you logged it with the feedback tool?  I have experienced slow models in the past, sometimes it because they have got on a server in a different part of the world to where I am working.
