Dimensioning a Drawing - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 629

using Aligned Dimensions
Aligned dimensions are linear dimensions that aren't horizontal or vertical. You
place them in the same way that you place horizontal or vertical dimensions
with the Dimension Linear tool. You can also use the Dimension Baseline and
Dimension Continue tools with aligned dimensions.
Use the Aligned Dimension tool, which works just like the Linear Dimension
tool, to dimension the line you drew at the beginning of this exercise. Follow
these steps to add an aligned dimension:
1. Zoom into the lower-right corner of the cabin roof.
2. Click the down arrow on the right side of the Annotate tab ➢
Dimensions panel, and then click the Aligned button.
3. Press ↵ to switch to accept the Select Object option.
The cursor changes to a pickbox.
4. Pick the diagonal line. The dimension appears attached to the cursor.
5. Click to place the dimension. Your drawing should look similar to
Figure 12.39.

using Angular Dimensions
The angular dimension is the only basic dimension type that uses angles in the
dimension text instead of linear measurements. Try making an angular dimen-
sion on your own. Because the default arrowhead style for the A-DIMS-PLAN
dimension style is Architectural Ticks, you'll want to create another child style
