Exercise 3 – Creating Fasteners Without External References
The default setting of Creo Intelligent Fastener is to use external references for fastener placement. Depending on your company guidelines, you can change this setting and work without external references.

3. Set the value of option USE_EXTERNAL_REFERENCES to NO.
4. Click OK to confirm the change and close the dialog box.

* Due to the configuration change, the fasteners do not have external references. Therefore, the holes no longer align with the screws.
