Problem export from Max

Hello,

I have a model in Max, that model has a link of a dwg. file. I have the geometry in two layers and all the parts are align. When i export from Max to Unity like fbx the situation of the parts change and doesn’t stand align. Anybody could help me?

Regards.

What have you done to attempt to overcome the issue?
Is your dwg link an xref link?
What happens when you import all mesh and remove the link and export?
What happens when you combine all mesh onto one layer and export?
Are all your mesh objects scale @ 100%?
If no - reset xform and fix normals then export.
Test out all setups mentioned above to see if any of those work - and update with more info.
