This is an old thread, but it came up when I searched for a possible solution for an issue I am having.
What I do for AutoCAD dwg files (under windows xp) is go to Folder Options->File Types->DWG->Advanced->New
Then in Action I put a description, like Print 11x17 and under Application used to perform action it would be:
"c:\program files\autocad 2004\acad.exe" "%1" /nologo /b plot11x17.scr
So then for running a script on a txt file on right-click, you would put "perl -w" code.pl "%1" or whatever.
What it does may be irrelevant but it runs a script then closes. This means you can highlight many dwgs, right click and have 12 copies of autocad open, run a script, then close.
This brings me to a question I have.
If I run more than 3 autocads at a time it will take much longer than if I did each file individually which has prompted me to attempt to put together this dal right here (note, I am very new at this so the code might look retarded):
This does exactly what I need to do, which is make a kind of queue. But how an I arrange it so I can highlight 20 file of only the dwgs I want and have it achieve the same thing without having to type in all the file names on the command line or make a batch file.
I thought about doing the folder thing, where it would process all the dwgs in a folder, but this is not what I want. There will be drawings in the folder I do not want to run.
