Hello!
I am glad to welcome all to this wonderful forum, I must say a great resource on which collected a huge amount of useful information and smart helpful people. Long since I read, but here's the first time confronted with a problem that is hardly brighten.

What I have:
model format. max
3ds max
unigraphics

What I need:
surpass this model in unigraphics and create on its basis the control program

What I did:
through numerous experiments with converting files (DXF, DWG, IGS, IGES, OBJ ...) I managed to drive the model in unigraphics, but work with it fully fails because this model depends as what is not clear element which can not be moved or scaled . it can not do because of the fact that when trying to select an object, he does not stand out.

Optional:
model originally is hollow with a minimum wall thickness, maby it must be converted into another object

please, help me deal with the problem...

sorry for my english
