I have a customer with a front entrance to a building that is a little out of the ordinary. I had one of my guys go out to draw and measure. He came back so I could get the square footage and both the drawing and measurements were off. He went out again and still not right to calculate. I then went out to get drawings an measurements. Came back to calculate the square footage and because nothing was square, I had to do some geometry. At that moment, the delivery of my new Moasure had arrived. So I said to my self..."Self, lets go and see what this does". I was there for 3 minutes traced the edge of the area, not only got the correct drawing, I got the correct "moasure"ments, a drawing, and the square footage... in 3 minutes. What a time saver. I have been using this a few times a week. Thanks for this great product.
