Bolt Properties Overview

You can use the Bolt Properties dialog to add, edit, or view Bolt Properties. Once you have set up a Bolt Property, you can assign it to a bolt in your model when adding or editing a bolt using the Add Spot Bolt dialog.

Using the Bolt Properties Dialog

To open the Bolt Properties dialog:

  • Select Bolt Properties from the toolbar or the Support menu.
    Default properties are already defined for one Bolt Property (Bolt Property 1).

Bolt Properties

To define only one Bolt Property:

  • Enter the desired properties and click OK.

To define more than one Bolt Property:

  1. Click the Add button below the list of Bolt Properties.
  2. Select the new Bolt Property in the list.
  3. Edit properties as above.
  4. Repeat these steps for each Bolt Property you want to add.
  5. When you're done, click OK.

To copy properties from one Bolt Property to one or more Bolt Properties:

  1. Select the Bolt Property whose properties you want to copy.
  2. Click the Copy button below the list of Bolt Properties.
