- Hello, I have a python code to get the contour of the hatch
- However, if I set the “Geometry Scaling to Medium” mode, it creates the PolyCurve but it gives an error
- If I set it to “Large” mode, it doesn’t give an error, but the Polycurve cannot be created
- How can I fix this situation?

out.append(ds_polycurv)

Leave geometry scaling on ‘medium’ and the Python script should work fine. That warning about ‘outside the range’ is related to geometry display; content should process correctly.
