About Associative Dimensions in External References

You can associatively dimension objects from external references in the following cases:

• Attach an external reference drawing to a host drawing, and dimension objects from the external reference and the host drawing in the host drawing.
• Attach a nested external reference drawing to a host drawing, and dimension objects from the external reference, its nested external reference and from the host drawing in the host drawing.

Objects from external references are dimensioned in the same way and with the same dimension points as objects from the host drawing.

You can create any level of nesting inside the external reference and still dimension all nested referenced objects.

You will need the ability to dimension external references often when you are working in a project environment.
