Dear All
I had a problem when using Curve.Project and asked a question. Sometimes the direction of the Curve is reversed before and after the projection, and sometimes it is not, as explained below.
PolyCurve.Project was used to project NurbsCurve(A) onto baseGeomery(B), resulting in CurvesList(C ). Note that the directions of the two NurbsCurves are aligned.
If you look at the contents of C, you can see that the orientation of one NurbsCurves changed before and after the projection, while the other did not.
What is the specification of Dynamo that causes this?
Please check the DynamoFile attached if you need.
Please note that the creation of NurbsCurve(A) and baseGeomery(B) are done in the following nodes respectively.
I would be very grateful if you could answer.
