A few years ago, using piles of borrowed code from africad (xtools) and some from here and a few other places I kinda slapped together some tools for attaching/overlaying multiple files at once, placing them on created layers named for the xref and other stuff. It depended on doslib for the file dialog box dipsy-do which is okay IF you have the latest version of doslib. I'd like something NOT based on doslib, that will allow something similar;
example:
XAZ - attach multiple files selected from multiple directories at 0,0,0 and placed on a layer created for each xref. Prefix the xref and layer names with "Z-"
Drawings CAT, DOG, and MONKEY are attached as Z-CAT, Z-DOG and Z-MONKEY and placed on layers Z-CAT, Z-DOG and Z-MONKEY respectively.
or maybe a single attach function that prompts for prefix if any .... hmmmm....
