Windchill and AutoCAD External references

Hello everyone,

I am learning Windchill and I am looking for information on how to attach AutoCAD external references, the referenced file can be another dwg, a tif or a pdf, all of them are in Windchill, including the main file.

NOTE: I know how to do it in AutoCAD when the files are in a shared or local folder, I am looking for a procedure or documentation on how to do it when the files are in Windchill.

I would appreciate any help or link.

Windchill version: 10.1

Thank you,

William Gonzales
