Automating the use of an ARX add-in in AutoCAD 2004

[geesamand]

Hello everyone, I'm new to this section of the forum.

We have a large catalog of Medusa files that are accessible only using AutoCAD 2004 and an ARX add-in that allow the user to browse to the medusa file and import into AutoCAD. The add-in appears to be graphical only, opening a dialog for the user to navigate to the file they wish to import. The Medusa files are stored on that computer in a variety of folders. We wish to script the operation of this import process to get them all in AutoCAD format and maybe also run a print-to-file step to get them in .tif format too.

The program might resemble:
- Load a list of Medusa files including full path and filenames
Loop{
- Run import ARX, feed in next Medusa filename
- Run print routine to dump .tif file
- Save AutoCAD file
}
(end)

Is Autolisp the way to go here? Can it automate the use of the ARX import utility(not part of the core AutoCAD interface)? Can Autolisp load the filenames/paths from an outside file? Any other possible roadblocks to consider?

Thanks for any advice before I send my IT department into it.
