You can set dimensions anywhere in a drawing. With the Angle dimension tool (see Figure 1) you can measure and dimension angles for walls or other components. It is easy to place an angle dimension.
Figure 1
To measuring an angle in an existing corner, follow these steps:
Pick the Angle Dimension tool on the Tools component tab.
Let the dimension find the corner (the point of intersection of the two walls) by moving the mouse pointer near the corner. Click it in place when it the word Intersection appears.
Point at one of the walls and click.
Next, move the mouse pointer in the direction of the other wall and click. The dimension is now in position and the current angle shown (Figure 2).
