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 diametric dimensions
  1. In a sketch with a centerline and lines or points, click Smart Dimension Tool_Smart_Dimensions_Relations.gif (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.
    The pointer changes to pointer _smart_dimension_radial.gif for radial dimensions and Pointer Smart Dimension Diametral for diametric dimensions.
  5. Select other lines or points in the sketch to create additional dimensions.
