I am having a bit of an issue with the output of ExtrudeCrv. I need to use a curved line that is the result of polylines and arcs, that has been joined into one open curve. I am using the curve to produce the top surface of a basic ground model for a larger project, but when I execute ExtrudeCrv, the resulting surface has weird lines on it (pictures attached). Initially, I wondered if it was simply producing lines because of the input curve’s control points, but I am unsure if this is the case.
I need to run Make2D afterwards, and the lines significantly slow the process down when producing the final drawing. I wanted to know if anyone could explain how to remove these lines? Or, also, what the cause is? Problem file is attached below.
