Hello,
In order to interpolate a cross-section properly, the two outer sections need to be structural ident. In your case, that means you need to check the cross-section points (in the result viewer or directly in SOFiPLUS(-X)). Make sure that the points of the two cross sections are named identically.
Here’s a short example project:
Querschnittsinterpolation.sofistik (33.2 KB)
Querschnittsinterpolation.dwg (52.5 KB)
Another way to solve variable flange height, as @sofijahris said, is to use variables.
If you need more information, please visit our website and watch the following tutorial.
