Just another trick about scopeboxes. Imagine you have a design from which a floorplan looks like this.
Setting up a project north to draw orthogonally is only going to help you for one part. But what about the other parts. Use scopeboxes!
Draw 3 scopeboxes
Rotate the scope boxes accordingly
Assign the grids to the proper scopeboxes
Create 3 views
Assign each scopebox to its own view
