"The Takeoff-Live People have been a great help all the time I'm needed anything. The product maintains an estimators "tape and scale" routine. You don't need to know cad concepts, Just open file, check scale, create Library on-the-fly, or just start measuring. Excel accepts your takeoff data nice and easy. Great tool for most trades, its capacity has been improved to handle larger plan sets and more. Always getting better but core usability never changes. You suggest an improvement, sooner or later it is incorporated if merited. If you haven't used it, try it. If you used it a bit earlier, you will love the improvements. When is the I-pod app version coming?"
