For example, drawing A includes a DWF underlay showing some mechanical
details. You need the content of drawing A attached to your current drawing,
drawing B. If you attach drawing A as an external reference to drawing B, the
DWF underlay that was already attached to drawing A is also be present.
All of the property settings made to the underlay in the external reference,
such as clipping boundaries, appear as they do in the parent drawing.
Password Protected Underlay Files
If a file you want to attach as an underlay is password protected, you are
prompted to enter the password after you have selected the file. You cannot
attach the file until you have correctly entered the password.
After an underlay is attached to a DWG file, you are prompted for the underlay
file’s password each time you open the DWG file. If the DWG file is also
password protected, or has several other protected drawing references attached,
you may be prompted for multiple passwords.
If you change the path of an underlay to a file that requires a password, you
are prompted for a password as well.
NOTE DWF, DWFx, and PDF file passwords are case sensitive but DWG file
passwords are not. To make synchronization between DWG and DWF file passwords
easier, make sure the DWF, DWFx, and PDF file passwords match the DWG file
password and are entirely uppercase.
