# Divide warp arc and model in tekla

i have aproblem when divide arc and send it to tekla it’s look like that

how to solve it ?

Hi, you can use the Beam Rotation component to calculate the needed rotation for the different parts. Assuming here that the beam should be oriented according to the plane of the arc:

The axis for a beam in Tekla is a vector from the first to the second control point. An arc is a bit deceptive in this sense, since the second control point is actually the mid-point as you can see in this pic:

Which is why the vector is created the way it is in the definition above.

Cheers,

Sebastian
