when I import the dxf file in Inkscape there are many single objects (lines) and points. In the svg file it is one object. Am Di., 22.

after exporting the object of the .svg into dxf (attached) then it works (but in wrong proportions) Am Di., 22.

Thanks dpa, those unwanted elements sound like the cause. I’ll get into it again tomorrow. -- Terry > On 22 Jun 2021, at 18:59, dpa <sc@pankd.de> wrote: > >  > after exporting the object of the .svg into dxf (attached) then it works (but in wrong proportions) > >> Am Di., 22.

dpa: I opened your revised DXF in OpenSCAD but the proportions seem correct to me. (x/y = about 1.75). Do you mean it's displayed at a different size and screen position? If so, that's a related aspect I have yet to understand! Specifically, to get the OpenSCAD scale markers to show the correct (physically measured) size, is the recommended method to do that in Inkscape (or maybe QCAD), or in OpenSCAD? And if the latter, what is the best way to proceed please? When I repeated opening my DXF, this time I got: WARNING: Unsupported DXF Entity 'SPLINE' (fc) in "Outline2Black.dxf". -------------------- Opening my original DXF in Inkscape again, and zooming in, should I have removed those remaining red marks, and if so how? Is that what you did before saving your DXF? P.S: Anyone know why my messages are shown from "terry pinnell - via Discuss", instead of "Terrypin"? Probably something I've set incorrectly since abandoning the defunct forum, but so far haven't found it!
