I have a problem when I converted 2d dwg to 3d SW model with SolidWorks 2020, see attached please. On 3rd screenshot you can see, I can not do any operation with "2d to 3d" commands.
The 2d drawing was save as from a slddrw which I created as a sample model with SW. I tried to convert other 2d dwg, there was a same issue.
I need help to fix this problem. Thanks,
