Adding Callouts for External Threads

In drawings, you can add cosmetic thread callouts to external cosmetic threads.

The thread callout is defined in the Cosmetic Thread feature of the source part or assembly. You use the Smart Dimension tool to add the callout in a side view or section view of the external thread.

To add the callout:

  1. Click Smart Dimension (Dimensions/Relations toolbar) or Tools > Dimensions > Smart.
  2. Select the two silhouette edges of the cosmetic thread.
    The pointer changes to when it is over a silhouette edge of a cosmetic thread.


  3. Click to place the dimension.
    The thread callout attaches to the outer geometry of the cylinder.
