I have a quite complex closed path with several thousand vertices created in a CAD Software. I can export it as dxf or svg and easily import it into OpenSCAD and linear_extrude it. Nonetheless, I'd like to create a BOSL2 path (an array of vertices) out of it to be able to extrude the path with chamfers or fillets. Unfortunately the path is not convex such that I cannot simply do hull() { linear_extrude(height = 0.01) import(file = "path1.dxf"); // the original path translate([0, 0, 1.99]) linear_extrude(height = 0.01) import(file = "path2.dxf"); // the path offset by 2mm } to get the 45 degree chamfer. Is there any option to convert / import the dxf / svg such that I get a path object that can be put into BOSL2 operations? Creating the array manually from the svg <path... is not an option due to the large number of vertices. I'd prefer to avoid to use external programs or Python etc. scripts. I thought about projecting the shape and getting a path out of the projection but that doesn't seem to work.

You can use the pathbuilder library to do this https://github.com/dinther/pathbuilder include <pathbuilder.scad> svg_d = "M 10,10 L 100,10 C 100,50 50,90 10,90 Z"; // Get the point list — returns a list of lists (one per subpath) pts = svgPoints(svg_d); Of course, this requires you to paste the svg content into a string in your scad file.

This works like a charm, thank you. > Am 05.06.2026 um 20:43 schrieb Adrian Mariano via Discuss <discuss@lists.openscad.org>: > > You can use the pathbuilder library to do this > > https://github.com/dinther/pathbuilder > > include <pathbuilder.scad> > > svg_d = "M 10,10 L 100,10 C 100,50 50,90 10,90 Z"; > > // Get the point list — returns a list of lists (one per subpath) > pts = svgPoints(svg_d); > > Of course, this requires you to paste the svg content into a string in your scad file. > >> On Fri, Jun 5, 2026 at 12:35 PM Thomas Richter via Discuss <discuss@lists.openscad.org> wrote: >> I have a quite complex closed path with several thousand vertices created in a CAD Software.

You can also use the experimental roof() module to chamfer non convex 2d geometry such as text that can't easily be converted to BOSL2 paths.

I convert 2D dxf path to bosl2 turtle commands with python script. But currently only MOVE and ARC entities supported
