Chapter 20: Referencing Other Drawings

In This Chapter

Introducing external references

Editing external references from within your drawing

Controlling the display of external references

Managing external references

Working with underlays

Sometimes you need to refer to another drawing without inserting it. You may want to use part of another drawing as an example for your current drawing, or to see how the model in your drawing fits in with models in other drawings. You may want the flexibility of seeing the other drawing sometimes, but not seeing it at other times. Using an external reference is like laying one drawing on top of another and being able to see both at the same time. You can easily load and unload the other drawing.
