Hi, I seem to have found a bug with the native “Project” function.
Take the simple example -
Create a sphere.
Place a single point inside the sphere
Select the “Right” viewport
Run the “Project” command
One point is created on the “right” side of the sphere, but two points are created on the “left” side of the sphere.
I’ve recently moved from Rhino 4 to 5 and this seems to be a bug introduced in Rhino 5.
