I used a program which has already been created called SWupBB. Here is the link to the download. If I could modify the code for the program to add .igs that would be great, or another standalone program works too.

I found a great SW add-in which will automatically save .pdf, .dwg, and .dxf to a specified folder everytime I save a drawing. This reduces alot of time saving over and over in multiple formats. I am wondering if anyone knows of an add-in which will save and .iges file to a specified location...
