We do have triangulation on board as part of PKNail, and the Disto will calculate slopes from distance, however, the program was designed to capture 90%+ of all buildings quickly and accurately, so that it could be quickly deployable technology. However, if you come across a very particular or geometrically complex building you may need to use another tool in conjunction. Were always open to the market. Thanks for your interest and comments.

I am interested... But I'm worried about precision. If you are wrong by 1 degree on 100 feet then error is ~1feet and 10 inches (even if your precision 0.1degree it a 2 inch error).

What if building walls are not 90 degrees (top view)?... looks like I need to do some additional work to draw more complicated wall design. (for example as if building had rhombus shape. If you not using the angle than you will get a square shape)
