Copy a 3D view between projects. Suppose you made the perfect 3D view in
your last project, and you can't figure out how to get it into your current project.
Fortunately, there's a way to copy views from one project to another. Open both
files in the same instance of Revit Architecture, and then do the following:
1. In your perfect view, right-click the 3D view in the Project
Browser, and choose Show Camera from the context menu.
2. Press Ctrl+C to copy the selected camera.
3. In your new model, press Ctrl+V and click in the view to paste
the camera. The view and all its settings are now there
(alternatively you can use the Modify ➣ Paste Aligned to
Current View to paste the view).
Disallow joining for walls. By default, Revit Architecture will join walls that
intersect; however, you will eventually run into a condition where you need to
override this behavior. First select a wall and hover over the Drag Wall End grip.
Then right-click and choose Disallow Join. This will unjoin the wall and give you
additional control to drag the wall end without it automatically jumping and
joining to the intersecting wall.
