You can create dimensions by:
- Selecting the entity to dimension and specifying the dimension line location.
- Specifying the extension line origins and the dimension line location.
When you create dimensions by selecting an entity, the program automatically
places the extension line origins at the appropriate definition points based
on the type of entity you select. For example, the definition points are located
at the endpoints of arcs, lines, and polyline segments. When you create dimensions
by specifying the extension line origins, the points you specify determine the
definition points. To establish these points precisely, use entity snaps.
You can create dimensions in model space or paper space.
