3D Model, Degenerate and Unsupported

[Anonymous]

 I am making a 3D model when I use the region command, 3 out of 4 of my columns are saying they are degenerate and unsupported. I do not know what to do and fix them to be like the first column.

Hi,

you can't use command _REGION for 3D-Solid objects (>>>details<<<).

Besides of 1 Line and 1 MText object there are only 3D-Solid objects in the drawing. What for do you need (2D)Regions-objects when you already have extruded (3D)objects?
