Hi @2022282210229 .

All elements in the sketch must be 3D.

If they are NurbsCurve3D, they can be included in the sketch using the SketchFixedSplines.addByNurbsCurve method.

What is it that you're trying to do? After creating a SketchFixedSpline you can use the replaceGeometry method to update it with a new NURBS definition.
