Make rhino compatible with bricscad and viceversa using dwg?

When importing a dwg from bricscad to rhino, rhino usually fucks with object displacement and some layers

When exporting from rhino in dwg then opening it bricscad, the same errors might happen, and the opacity of some objects goes off, so you’re there at fixing stuff rather than doing your job.
Also a common issue is that the exported scene from rhino to bricscad is that the scene doesn’t appear (it’s too small)

How do these files come into autocad? We’ll need to establish a baseline between the three programs to see what is going on.

Do you have a small example?
