I have changed jobs was using AutoCAD lt 2007, now I am using AutoCAD 2009 mechanical. I downloaded Lynn Allen tips and tricks for cad 2010 and 2009. I actually do electrical drafting/design, but oh well. There is a copy of AutoCAD mechanical 2010 in my desk drawer I'm not sure why the 2009 version was installed and not the 2010 as they got them at the same time I am learning. Are there any tips and tricks specifically for AutoCAD mechanical? I think I might install mechanical 2010 here in a moment and play with it, see what I can figure out. I also have a copy of AutoCAD 2005. Wooh ho!!!!
