Hello,
I am to create a DXF file, containing polylines describing a profile. The polylines contains arcs and lines. When exported into dxf files, the polylines contains only vertexes, which is exactly what I need.
But the tesselation is not detailed enough. Is it possible to have the arcs approximated by lines during the export?
For example, with another software, the parameter is the maximum angle between two consecutive segments.
Thanks in advance.

The vertex and the bulge fully define the arcs. you need to look up the terms polyarc and bluge.
