Thanks for your reply. I have searched keywords "BSpline parameters", and the page said these are too common, search query were ignored, no results would be shown. I will try "Chris_G".

I am working on a project which takes wires from a 3D model shape. And then convert it to paths for laser cutting. Here, I got a wire from my client. When I am trying to convert the bspline into arcs, its shape changes. I use the python console to check the parameters and find the differences. a=App...

I use the fontforge to open the 1CAMBam_Stick_9.ttf file and find that the characters consist of overlapped splines. So I use ShapeAnalysis_Edge.CheckOverlapping to filter the overlapped edges. This works.

I found a problem, single-line (stick) text will be converted twice, and the lines will overlap. I want to convert it to a cutting path, but it will still cut twice, affecting the cutting efficiency.

In AutoCAD 3D mirror them or create new circles. ... the same trick seems to work here that wmayer recommends for problematic step imports: load in varicad viewer and save in varicad viewer. import the result into freecad. it worked with this file Bildschirmfoto_2023-03-21_12-13-06.png Thank you fo...

Thank you for your reply. How can I deal with it so that FreeCAD can open this dxf file with the same effect as AutoCAD?

Hi, I want to import the attached dxf file into FreeCAD. I found that the circles got wrong position (seems their X value are opposite). I don't know why and I don't know how to fix it. They display well in AutoCAD. https://user-images.githubusercontent.com/12094269/226536831-1a39ef49-95f9-42f5-89f5...

Many Thanks

Thanks for your reply. I intended to discretize the b-spline, but my leader thought it was too fragmented and was not suitable for laser cutting. The machine can go more smoothly by circular arcs. So I need to shorten the curve for every GeomAbs_BSplineCurve in case of symmetrical B-splines ?

I am trying to convert a contour to the combination of lines and circular arcs, I call the function toBiArcs(0.01), then I encounter this issue. As shown in the picture, the green curve is the origin, and the red one is the fitted curve. At the right side, two curves seem to mismatch where two arcs ...
