Dimensioning to a Mid-plane Line

  1. Click Dimension in the Annotation group on the Detailing tab .
  2. Define the mid-plane line:
    1. Select a face or edge:
    2. Hold Ctrl and select a second face or edge:
    The mid-plane line is displayed as a gray line, and the beginning of the dimension is attached to this line.
  3. Select the face, edge, or point you want to dimension to.
    The end of the dimension is attached to the face, edge, or point.
  4. Click to place the dimension annotation.
Note: You can reverse these steps to begin the dimension with an existing line or point and end the dimension with a mid-plane line. You can also dimension between two mid-plane lines.
