You will aways have a Z vector. For this component only the direction of the curve matters, not the magnitude (length).

What would you expect to happen?

Hi Arend , I would like to change the "angle of attack" of the arc, by modifying the tangent vector!

See the attachment, thank you !

Hi Anton 

Here is the solution.

In your solution your tangent vector is in xz plane. No mater whatever the value of z, tangent will remain same. That will give you only a half circle.

It works fine on your example.

In my project the two point d0 not lay on the mentioned plane (xy).

It means i.e. that the coordinates of the first point are (0,0,0) and the coordinates of the second point are (5,0,-10).

So the solution does not work :-(
