Thx for the info!
Dxf from SketchUp are specific because curves are polylines so numerous "control points" !
Maybe Circles and Arcs can be exported as real curves...
With this one by Joergberg (for SU Make)
So circles and arcs are not "segmented" !

As we can see for the circle...that is a true curve!
