Dear Dale @dale
I have some Problem with this curves - as fare as i can see, they are coplanar and they intersect.
rhino-Command _intersect finds the points
rhino-Command _curveBoolean fails - open red curve result
RhinoCommon Curve.CreateBooleanIntersection fails as well (i would need the RhinoCommon - Method to work …)
Maybe a bug ?
thanks for having a look at it
