Anyone use such program? I need to be steered in the right direction. I don’t want to install a bunch of free programs only to try them out and have them be crappy or loaded with spyware or such.  
I got some CAD drawings on a disk that I mostly want to just view, but there may come a time when I’ll need to make some changes too.

Thanks

[Autodesk Design Review](http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=2404513) is free. I’ve not used it myself, so can’t comment on its utility, but it’s from the makers of AutoCAD.
