Surface plane at parameter

Geometry
1

Simple question, but how to get a plane at the certain point of a surface? (Dynamo has a “point at parameter” node so why there is not “plane at parameter” node?)

hi Harri,
to place a plane at a certain parameter you have to use the points as showed in this image.
So you can create a plane centered in a root point.

Agreed, and already suggested on the Dynamo GitHub: https://github.com/DynamoDS/Dynamo/issues/6566

In the meantime, simply use Surface.TangentAtVParameter and Surface.TangentAtUParameter to generate planes using the Plane.ByOriginXAxisYAxis method. Its inefficient (thanks to the number of profligate tessellations) but better than nothing:

Thanks for both! Thomas, those are the nodes i’m looking for.
