Creating Symmetrical Angular Dimensions

You can create multiple half and full symmetric angular dimensions without selecting the centerline each time.

This type of dimensioning is helpful when you create sketches for revolved geometry that require several angular dimensions or the display of a full angular dimension.

Multiple half angle and single full angle dimensions

To create a symmetrical angular dimension:

  1. In a sketch with a centerline and lines or points, click Smart Dimension (Dimensions/Relations toolbar) or Tools > Dimensions > Smart.
  2. Select the centerline and a non-parallel line.
  3. To create a half angle dimension, move the pointer to the desired location. To create a full angle dimension, press and hold the Shift key.

    The pointer changes to indicate that you can place multiple angular dimensions using the centerline.
