Curve.ExtrudeAsSolid operation failed. Could not make patch surfaces : API_FAILED -- operation unsuccessful


Does anyone knows if this problem was caused by the shapeFilePath?

Could you turn on the outputs of all the nodes you got ? Especially Shape.GetAllShapes ?

I suspect the error you have is coming from the curves you are using. They maybe do not form a closed polycurve.

The output of Shape.GetAllShapes was a function not a curve, that was the reason! I fixed and all worked! Thank you for the help!
