Can you Internalise the Brep and the Point and upload it?

Thanks for the reply David.

After you asked that, I was curious, so I baked the surface geometry. What's strange is that when baked, the surfcp component works fine. But when the same surface is fed into the component without being baked, it returns the incorrect result. Uploading the whole definition.

Thanks again,

Matt

This Python script reproduces the Grasshopper output, not the Rhino output, so Rhinocommon is at fault compared to what Rhino is doing:

import Rhino

ClosestPoint = S.ClosestPoint(P)
