Chapter 18 Creating Dimensions
Baseline Dimensions
In baseline dimensioning, each dimension in the series seems to extend from
the same extension line. Use baseline dimensioning when you need to show
several dimensions measured from the same point.
Unlike single dimensioning, baseline dimensioning does not allow you to
customize each dimension individually, as you draw. Instead, it uses the
current settings in the Dimension Format dialog box, incrementing the
initial offset by the baseline offset with each new dimension in the series.
To draw a series of baseline dimensions
1 On the Draw menu, click Dimension, Horizontal, Vertical, Rotated, or
Aligned, or click the appropriate dimension button on the All-In-One
toolbar. The edit bar displays controls for linear dimensions.
2 From the Dimension Method drop-down list box on the edit bar, click
Baseline.
3 Enter the initial offset on the edit bar and press ENTER. This is the distance
from the dimension line to the closest dimension point on printed
output. It applies to the first dimension only. For information on chang-
ing a linear dimension after it is drawn, see page 231.
4 Enter the baseline offset on the edit bar and press ENTER. This is the
distance between baseline dimensions on printed output.
5 Enter the first dimension point. A rubber-band dimension appears,
moving with the pointer.
6 Enter the second dimension point to complete the first dimension. Notice
that where you place the second point determines the orientation of the
dimension. You can reverse the orientation of the dimension by pressing
CTRL as you enter the second dimension point.
