External References

Back      Next


When a feature in a model is referencing some geometry or information in any other model then such reference is called “External Reference”.

Generally, external references should be created only between a skeleton and a given model. External references between any other models are difficult to manage and should be avoided.

In this chapter we will see how to investigate the external references in a design project. We will look at the following tools that are used for external references investigation.

  1. Reference Viewer
  2. Reference Information Window
  3. Model Tree


The topics covered are as follows.

  • How to investigate the external references using Reference Viewer and Full Path Display dialog boxes.

"I was impressed with how thorough the tutorials were. I have been using Pro/NC for years but still learned many new techniques. 

I have taken many classes through VAR's, PTC and Rand and have never been happy with them. I always left the classes feeling as though things were missed or scanned over quickly. Before I made things work but had to do more work to get the results I wanted. 

Your tutorials covered everything and are very intuitive. Highly recommended."
