Use drag controls to resize an element.
Drag controls display at the ends of selected elements in plan views. They also display along the ends, bottoms, and tops of selected elements in elevation and 3D views, where they are labeled as shape handles. Drag these controls to resize an element.
Revit uses the following types of drag controls:
- Dots (
) display when movement is constrained to a plane, as with walls and lines in plan views. Drag a dot control to lengthen, shorten, or change the orientation of the element. - Double arrows (
) display when the shape handles are constrained to move along a line. For example, if you add a labeled dimension to a family and make it an instance parameter, it displays with a double arrow after you load it into a project and select it.
