Space Claim: Automatically rotate component orthogonal to curve

Hello guys,

In the 1st step move the component along the curve and then in the 2nd step rotate the component orthogonal to the curve. I have the problem with the 2nd step. Depending on the position of the curve my Part get a different rotation angle. Is there a function in Spaceclaim that can automatically return the angle of twist orthogonal to the curve. So i want to automate it with python script .

I hope you understand what I mean.
