Revit newbie questions:
How do you rotate the view on screen so that it becomes orthogonal to the appropriate axis?
The Autocad equivalent is to change the UCS rotation and then type the command plan and current UCS.

What is a scope box?

What is the difference between a drafting view and plan view?

Thanks for any help provided!

There is no UCS as in Acad in Revit. Read the help sections about Plan North and True North...it is very important to understand. Preferably you would draw your building with vertical and horizontal walls aligned along the vertical and horizontal of your view. Of course that's not always possible :) To rotate your view, go to your view properties to make sure Crop Regions are turned on and are visible. Then select and rotate your crop region and the view will rotate.

This will feel a bit "unnatural" until you understand what's going on. You basically need to rotate the crop region by a number of degrees equivalent to the angle of the wall that you want to be horizontal/vertical. Rotate your crop region so one of the sides is parallel to your wall. Crop regions can only be rectangular with vertical and horizontal edges, so once you finish rotating, the crop region will resume its "usual" orientation, while your view will rotate in the opposite direction as you rotated the crop region.

Scope boxes are intended to help you control visibility of datums, such as gridlines. Suppose you have a building with gridlines that apply to one area only. You can draw a scope box over that area, assign the applicable gridlines to that scope box and then assign the scope box to a view. If the cut plane of that view intersects the scopr box, the objects assigned to it will be visible. This will help manage which datums show up and which ones don't. You need to read through a bit on your own in the help.

A drafting view is just like a sheet of paper on a drawing board...it has nothing to do with your model. It's where you can draw 2D details. You cannot see the model from it. A plan view is a view of the model and what you see is what your cut plane intersects, and what your bottom plane and view depth of your view range see.

Scope boxes also can control the crop region of views. If you have many partial plans a scope box can ensure that every partial plan view assigned to the same scope box will have identical crop region adjustment. In fact the only way to alter the crop region of a view that has been assigned to a scope box is by altering the scope box.
