Add a Dimension Aligned with an Arc Wall

You can place aligned dimensions from the center of arc walls to other walls or lines.

1. Click Annotate tabDimension panel (Aligned).
2. Move the cursor over the arc wall until the center mark (+ symbol) displays. You may need to zoom in to see the + symbol.
   Note: By default, the arc center mark is invisible. You can dimension to it without displaying it by moving the cursor over the arc until the center mark highlights. Arc center marks are visible only in a plan view.
3. Click to start the dimension.
4. Place the dimension between the arc wall center and any other component you wish to dimension.
