To help us look at some of the differences, I've got the exercise file modeling c-plane dot three d m open. each viewport and Rhino has a construction plane, that acts kind of like a tabletop where we do our work, so when we draw or pick points in the viewport, the cursor is always on that construction plane, unless we use something like snapping or elevator mode or planar mode to set points off of the construction plane. So we can see an example of that, just drawing a freeform curve. So let's go up to the Curve menu and under Free Form, let's just draw a Control Points curve. Now, as I draw in the perspective viewport, all of the points that I set are going to be landing on the world's top construction plane. So, the perspective viewport actually shares the construction plane with the…
