AUTOCAD 2008 PREVIEW GUIDE
Creating Dimensions
AutoCAD 2008 offers new and enhanced dimensioning functionality, which includes automatic alignment
options, dimension breaks, jogged dimensions, text placement, and tolerances. The new Dimension panel on
the Dashboard provides easy access to the many dimensioning tools.

The new Dimension Break tool (DIMBREAK command) enables you to break dimension or extension lines
where they intersect geometric objects or other dimensions. After specifying the dimension that you want to
break, you can select intersecting objects to use as cutting edges or you can choose the Auto or Manual
options. When you break a dimension by selecting objects or using the Auto option, the breaks will
automatically update when the intersection point moves. If the objects are moved so that they no longer
intersect, the break will disappear and if they are moved back the break will automatically return to the proper
location. The Manual option enables you to specify start and end point of the break. You can use the Restore
option to remove all the breaks from selected dimensions or leaders.

A new Inspection Dimension tool (DIMINSPECT command) enables you to create inspection dimensions,
typically used to indicate critical operating tolerances, from existing dimension objects. You can add or remove
inspection dimensions and control their appearance including the shape, label and inspection rate. After you
convert a dimension to an inspection dimension, you can edit the inspection dimension properties using the
Inspection Dimensions dialog box or the Properties window.
