I can't see mass

[nebojsa.jeremic]

First I import 3d from Autocad like mesh, a lot simple cubes, I made some mass and export back to Autocad, but I can't see mass objects, only old objects which I already imported.

Masses will not export unless the Mass Category is made permanently visible in the Visibility Graphics dialog.
