Placing Horizontal and Vertical Dimensions
Let's start by looking at the basic dimensioning tool, Linear. The Linear Dimension fl yout (the
Dimlinear command) on the Annotation tool set's Dimensions tool group accommodates both
the horizontal and vertical dimensions.
In this exercise, you'll add a vertical dimension to the right side of the Unit plan:
1.
Before you start to dimension your drawing, you need to set its scale. Select ¼˝ = 1´-0˝
from the Annotation Scale pop-up menu on the Status Bar palette. Metric users should
select 1:50.
2.
To start either a vertical or horizontal dimension, click Linear Dimension from the Tool
Sets palette or enter
DLI
↵ at the Command prompt.
3.
The Specify first extension line origin or <select object>: prompt asks you
for the first point of the distance to be dimensioned. An extension line connects the object
being dimensioned to the dimension line. Use the Endpoint Osnap override, and pick the
upper-right corner of the entry, as shown in Figure 11.13.

SELECTING OBJECTS TO BE DIMENSIONED
The prompt in step 3 gives you the option of pressing ↵ to select an object. If you do this, you're
prompted to pick the object you want to dimension rather than the distance to be dimensioned.
This method is discussed later in this chapter.
4.
At the Specify second extension line origin: prompt, pick the lower-right corner of
the living room, as shown in Figure 11.13.
5.
At the next prompt, Specify dimension line location or [Mtext/Text/Angle/
Horizontal/Vertical/Rotated]:, the dimension line indicates the direction of the dimen-
sion and contains the arrows or tick marks. Move your cursor from left to right to display a
temporary dimension. This enables you to select a dimension-line location visually.
