dxf extrusion issue

mrJaros
Hi everybody. I have a strange issue when extruding a dxf file: entities after extrusion are extremely simplified, I mean they consists of very few polygons. No idea what I'm doing wrong

I've attached both dxf and scad file for easy reproduce (or deny) my issue on your machines:
test.scad
test.dxf

Thanks in advance for your replies!
dxf is created in LibreCAD and in QCAD, same effect.

Addidtional info:
I've created dxf using 'polylines' tool in LibreCAD and then I used Modify -> Round on edges.

Hi,

The problem is that OpenSCAD doesn’t support POLYLINES which is a mixture of arc and line segments. We treat each element of a polyline as a line segment. You can work around this in LibreCAD by using the “explode” function to break apart the design into separate elements.

Improving DXF import is a larger issue, see https://github.com/openscad/openscad/wiki/Project%3A-Improve-DXF-import-and-export

I also created an issue on this, in case someone fixes it independently of the bigger DXF project:
