You can create screw connections between simple parts by only selecting the parts. Creo Elements/Direct Part Library searches for holes in the parts and creates the screw connections.
To add a screw between simple parts,
1. Click Part Library and then, in the Screw conn group, click the arrow next to New.
2. Click Simple Parts. The Create Simple Parts dialog box opens.
3. Select the first part.
4. Select the second part.
5. Select the length for the screw:
◦ Automatic: This setting should be used with a connection that includes a nut. The length will be calculated for you.
◦ Automatic + short, Automatic + normal, or Automatic + long: Use these settings when the hole is threaded and no nut is required. The appropriate length is automatically determined, then the next longer or shorter length for the standard is used.
◦ Part: You select the screw from the library and choose its length.
