When i import an AutoCAD file in RSA, some times it gives error and the program crashes and closes.
I then realized that i should delete all hatch pieces and other regions and text ,..... etc keeping only line and polyline objects.
I wish that error can be fixed in the upcoming version.
Another thing,
All arcs drawn in AutoCAD is converted into lines when i import the file in RSA.
I wish this also will be repaired to get full view of the arc as it is drawn in AutoCAD.
