I’m in need for prepare some construction parts which I did in rhino and gh for the export in dxf for laser cutting. I already converted splines in arcs and lines but the laser cutting company asked for less points in the geometry.
The picture following shows my file when the laser cutting company opened it with their software. Can somebody help me how to reduce the points of that geometry or at least how I can show all those points in Rhino?

I guess it would be possible for the cutting company to produce the part with that file version, but we try to optimize the data for economical reason. There will be around two hundred similar but unique parts.
I already converted the NURBS to arcs and lines but it seems that the output ist still not satisfying.
PointsOn command shows me exactly the point which I already posted in the former picture… but not the many points which are visible in the software of the laser cutting company.
Is there maybe some other parameters I can try when I export my geometry?
This are the parameters which I used to export my file
Might be good to post the file here so someone can do some tests… What I see is the last item in your settings - how polycurves are exported - is set to ‘polylines with bulge arcs’ (English equivalent). What you have is a polycurve composed of lines and arcs, but I’m not sure how that setting reacts in that case - I would think that it would be ‘transparent’ just sending along your joined lines and arcs as they are, but maybe not.
If you explode your polycurve before exporting, does the laser cutter software do any better with it? Most the laser cutter control software can chain separate curves back into one path. The other thing to check is if the curve you are exporting really has only arcs and lines in it, and there isn’t a NURBS curve segment in there that is causing Rhino to treat it as a spline or something.
