Did a bit of searching I wasn't really able to find what I'm looking for.

I'm often working with 3-6 different assemblies a day for different products. It's common that I will have to make minor changes that affect all of the parts and have to individually go to each part and save as an IGS for my cnc programmer. I'm looking for a macro that does just that: from an assembly, saves all the individual parts to IGS. It would be a bonus if I could do this from the drawing file, where it saves every part with an active drawing view to an IGS file while saving the drawing to a PDF.. but I figure that's asking a bit much.
