Error using sketch3d for lines.

[r.ziethen]

Connecting 2 Sketch3D-Lines there arise an error, becuase between the two lines the API puts an circle with an radius of 5 mm.

Hi @r.ziethen.  Just based on your initial statements, and without even reviewing your code, if the problem is because of the automatic bends / radii, then there is a way to turn that off, if needed.  Within Inventor's application options, on the Sketch tab, there is a setting under the "3D Sketch" heading, named "Auto-bend with 3D line creation".  You can uncheck that checkbox.  Then, if you just want to control the radius of that auto bend, you can go into the document settings (Tools tab, Options panel), to the Sketch tab, and there is a setting under the "3D Sketch" heading, named "Auto-Bend Radius" that you can change.
