I found out that arcs are turned into bsplines, is there some way to preserve the arcs in the conversion to DXF? Let me know if need a sample.
Thank you

After more testing it appears that it is view related. I have been using this post as a reference:

There was talk in that post about a view issue, was there some proof to view related issues with export?
Thanks

Without looking, my guess would be that the arcs are turned into splines in the HLR routines, not the conversion to DXF.

OCC loves splines. It even returns splines in place of straight lines sometimes.

There is some code that tries to guess if a given spline can be represented as a line or a circle for drawing and dimensioning. Might be able to use this in the exporter.

Not sure when I'll get to this though.
