You can group entities within
dimension bounding boxes to accelerate dimensioning. Dimension bounding boxes help you
to align the dimensions of assembled entities along the box margins at defined
offsets.
The dimension bounding box is represented by a gray dashed rectangle on the X-Y
plane.
The software links the enclosed entities with the bounding box. The dimension
bounding box updates automatically when the geometry of selected entities changes,
existing entities are deleted, or new entities added. Moving or copying the entities
from the bounding box automatically moves or copies the dimension bounding box as
well.
After you create the dimension bounding boxes, the
SmartDimension command uses them to line dimensions up with
each other. Also, dimension widgets can assist you to assign dimensions at defined
locations.
You cannot select and edit the dimension bounding box in the graphics area. The dimension
bounding box updates automatically as the set of entities changes.
Dimension bounding boxes update automatically in the following situations:
- Existing geometry changes
- New entities are added to the bounding box
- Some entities are deleted from the drawing
- Some entities are removed from the dimension bounding boxes
