Click on the link above and you will open Lynne Allen's Blog post announcing that her free AutoCAD 2009 Tips and Tricks booklet is available for download.
This booklet is full of useful AutoCAD tips and tricks from beginning to end. Some of them I had tripped over in my daily work with AutoCAD Civil 3D, in my land surveying business, but most were "AHA, so that's how you do that" moments.
Read this and I guaranty you will improve your productivity with AutoCAD immediately.
I rate this booklet 3 RODS out of a total possible 4 RODS.
