CreateViaThicken Curve loop

[prgmdl]

Hi,

I am having an issue using CurveLoop.CreateViaThicken(curveLoop, thickness, normal) if the curveLoop contains an arc it throws an exception the input curve could not be thickened. Is there a way to use this if the curveLoop contains both line and arc?

From the documentation:
If the curve loop contains curves such as elliptical segments or splines, it is possible the offset creation will fail if Revit will not be able to trim contiguous curves to meet one another. If the offset is successful, offsets of those curve types will be created as HermiteSplines.

This may be your case.

Hi,

Here are some examples. Both curve loops just contains a line and an arc but it seems to not work here.
