Re: Snapper : Line intersection with face

Perhaps like this: doc = App.getDocument("demo") line = doc.getObject("Line") cyl = doc.getObject("Cylinder") intersection = cyl.Shape.section(line.Shape) print (intersection.Vertexes[0].Point) print (intersection.Vertexes[1].Point) demo.FCStd intersection.FCMacro Screenshot 001.png

Re: flat solid spiral shape

It may be sensible to rename this function. "Binormal" tells an average user less than e.g. "Fix orientation". tangent - normal - binormal are frequently used mathematical terms to describe 3D-curvature. In short called "TNB frameset" I think renaming will lead to some confusion TNB frameset.gif
