Adding a Reference Dimension to a Model

This example adds an angle dimension to a chamfer at the end of a cylinder.

In the modeling environment, if the model view orientation is normal to an annotation or standard view, you can use the Smart Dimension tool to select silhouettes of the surfaces when their profiles are perpendicular to the view orientation.

To add a reference dimension to a model:

  1. With the model view orientation normal to the annotation view, click Smart Dimension (Dimensions/Relations toolbar) or Tools > Dimensions > Smart.
  2. In the Dimension PropertyManager, select Reference dimension .
  3. In the graphics area, select the silhouette edge of the chamfer. Notice the cursor changes from to when you hover over the silhouette edge.

  4. Select the silhouette edge of the cylinder.

  5. Click to place the dimension.
