Error in PlaneClosestPoint

I am trying to add a point on a plane created from a normal vector and intersection point. I get the following error: “Message: 73.4238978865307,18.7233568022929,-16.9420842473954 can not be converted to a Plane” (11.9 KB)

Well, you didn’t indicate exactly where (what line) your error is happening, but from the error message, it looks like you are trying to pass a point3d object where the method expects a plane object. Plane objects are composed of a point3d (the origin) and 3 vector3d’s.
