Using Centerlines to Create Radial and Diametric Dimensions

You can create multiple radial or diametric dimensions without selecting the centerline each time. This type of dimensioning is helpful when you create sketches for revolved geometry that require several diameter dimensions.

Multiple radial dimensions
Multiple diametric dimensions
  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 line or point.
  3. To create a radius, move the pointer to the near side of the centerline. To create a diameter, move the pointer to the far side of the centerline.
  4. Click to place the dimension.
    To insert a diameter symbol, in the Dimension PropertyManager, under Dimension Text, click .
    The pointer changes to for radial dimensions and for diametric dimensions.
  5. Select other lines or points in the sketch to create additional dimensions.
