How to convert Map type drawing into 3d. Extrude option does not work in autocad 2010 software and shows the error message that can't sweep or extrude self-intersecting curves.
you just need to use the command boundary to convert your drawing to a region then you can apply extrude command from solid panel and you will have what you want
for any more details just leave me a message
It could be extrude in the form of surface.
When it is in form of segments.The curve shouldn't be a polyline type.
If the desired curve is in form of polyline,then software give error.so first explode it make its surface then convert it surface to solid from modify tools..
