We just noticed that when creating a new sketch, the dialog differs, based on how you start it.
If I go to "Sketch in Task Enviornment" first, it look like this, and picking the horizontal direction is complicated.
If we select the plane first, then click "Sketch in Task Enviornment", it looks like the more traditional, NX9 in our case, dialog, and it's easy to establish the X vector.
Obvious first question, is why? and second, using method 1, what is the quickest way to establish the plane, and horizontal vector?
