Thanks for your help, Michael. So if I understood right : A different method of
building up the curve will influence the way how it is exported as DXF ?

Till now, I just used the script > reconstruct curve.

Noew I built the curve like you explained, but when I export this version as
DXF I still get a different point number and position ?

Hi Tom, yes if you convert any smooth curves into polylines and then export only the polyline, I would expect that the polyline should not be changed in the transfer.

Can you please post the .3dm model file with the curve you built in it and the DXF file you made from it that is giving you different points in it?

Oh sorry - I had overlooked that "polyline" is a specific command in MOI, I
thought that you had used it as synonyme for "curve" !

That means that I need to export curves with hard edges and than in
Cinem change them to Splines with rounded egdes - that is the work -
around, yes ?!

Hi Tom,

Yes, I think so. If you export a curve that has been converted to only have line segments in it and not any smooth pieces (this kind of curve is called a polyline), then I would think you should not have any variations in point arrangement or density in the transfer.
