Tips & Tricks: Reviewing and Editing References




Say you’re finalizing the model that you spent months designing. Just as you are wrapping up the model, a notification pops up about an urgent last-minute change request. The change means that a handful of the features need to be moved from one side of the model, to the other.

Luckily, with recent enhancements (in Creo 3.0) to the Edit References workflow, you can review and change those references with just a few clicks. Here’s how it works:

Reviewing a feature’s references

To view the list of original references for a given feature, follow these steps:

  1. Right-click a feature on your model and select the icon that looks like a chain link to open the Edit References dialog box. The dialog shows a list of dependency references.
  2. Click items on the Original reference list to view each reference on the model, as shown below.

Moving a feature by editing a placement reference

By editing a feature’s placement reference, you can quickly move that feature. To edit a feature’s reference, follow these steps:

  1. Right-click a feature on your model and select the icon that looks like a chain link to open the Edit References dialog box.
  2. Select the Reference that you want to edit.
  3. Click Roll To in the Child handling section of the dialog box to update the reference for all or selected downstream children.
  4. Select the new reference.
  5. Click Preview to see how the new reference will impact the feature, or click OK to apply the changes.

The Edit References utility highlights missing references in red. Best of all, it gives you a great level of control to apply the reference replacement to all or selected dependent (child) features as you make your changes.
