Dimensioning Two Points of the Same Arc

You can add a dimension where both ends are on the same arc, such as in the case of radii and holes where it is necessary to dimension both quadrants or the center and a quadrant.

To dimension two points of the same arc:

  1. Click Smart Dimension Tool_Smart_Dimensions_Relations.gif (Dimensions/Relations toolbar) or Tools > Dimensions > Smart.
  2. Shift + select the first quadrant of the arc and select the center or the second quadrant.
    You do not need to hold down the Shift key once you select a quadrant of an arc to start a dimension.
