One piece of software I use a lot - for printing multiple Autocad files

If you don't have the Batch print tool for Autocad, or even if you do, you may want to look at Print Conductor, a free piece of software for batch printing different types of files. I use it to plot multiple Autocad files. It is available here. This sure beats having to open each file and print separately. I created a pdf package of drawings by printing to PDFcreator, another freebie. It has a wait function, which will collect all the prints. Then you can merge them into one pdf file. Pretty cool.
