Hi Andrei,

> But one thing! How to control angle of this?

One possibility is if you shoot a 3 point plane coming straight off that chamfer segment edge, you can then select it and use Transform > Rotate > Rotate axis to pivot it by your specific desired angle.

The "rotate axis" transform allows you to pick any line as the rotation axis and your object will pivot about that line.

Just make the plane long enough so that it sticks all the way up through the object after it has been rotated.

Thank you Michael good solution!

Pilou Im not sure I understood your method.

It's just for regulate the 2 extremities of the object to boolean Diff from the big one!
Cut Path with 2 extremities choosen and sweep!
But caps are perpendicular to the path!

I suppose you know the Transform Orient / Orient for Slide an object perpendiculary (or not) to a path! :)
