"Rotating and Mirroring Elements - ...Revit provides a few methods for rotating elements. The time-saving spacebar is a quick way to rotate elements in 90-degree increments. Just press the spacebar when an element is selected... If a diagonal reference (wall, grid, or reference plane) is nearby, then the spacebar will locate this as a rotation candidate. For more precision, the Rotate tool is provided..."
"Using the Spacebar - ...to rotate elements both at the time of placement and after an element has been placed. ...a few examples:
Doors and windows - If you have a door with its swing in the wrong direction, select it and press the spacebar. You can cycle through all four possible orientations of the door with a few clicks. The same holds true for windows; however, many window families are built to only let you flip the window from inside to outside, because many windows are symmetrical in elevation. If you are creating an asymmetrical window on your own, be sure to add flip controls to the window family during its creation. These allow the spacebar to work on hosted elements."
"Walls - If you select a wall, pressing the spacebar flips the element as if it were being mirrored
about its length. Walls flip based on the Wall Location Line, which often isn’t the wall centerline.
If you aren’t sure which direction your wall is facing, select it and look for the flip-control
arrows. These are always drawn on the exterior side of walls..."
"Freestanding elements - If you select a freestanding element ...the spacebar rotates the element about the center reference planes defined in the family. Depending on how the family was built, the rotation origin may not make the most sense, but you can quickly orient your furniture and casework. If you decide to edit a family to change the location of the geometry relative to the center reference planes, be careful: when loaded back into a project, all your elements will jump to a new X–Y location based on the changes you made!" (Think editing the base point of a block in AutoCAD, everything will move based on the new basepoint when it's reloaded)
"Rotate tool - To rotate an element, select it and click the Rotate tool. ...two-click operation similar to the Move and Copy tools. Alternatively, you can enter numeric values. Revit locates the geometric center of the selected element or elements and uses that as the default center of rotation. ...fine if you don’t need to be precise... in most cases you first must designate a meaningful center of rotation. ...select and drag the center of the rotation—the rotation cursor—to a new location before clicking to set start and end picks. Once the origin is established, begin rotating the
element using the temporary dimensions as a reference or by typing in the angle of rotation explicitly." (entering positive numbers rotates clockwise, negative rotates counter clockwise)
Note: "...while moving the origin, you lose the ability to pan and zoom the view. To overcome this, drag the origin into the Project Browser and release the mouse button; then, move the cursor back into the view. The cursor changes to a rotation icon, and you can freely pan and zoom all you want. The next click you make places the origin..."
