Small Rafter Calculator

Hard to calculate the length of the rafters? The pitch?Well I work in Carpentry and is hard the pressure to calculate by hand the length of your Rafter or even show the hight of the roof without wasting material.
Is simple just enter the Length of the Gable Wall from the Outer side, enter the wall Thickness, Pitch and the thickness of the Ridge, and that's it, you got the length from the bottom part of the plum cut, to the Bottom of the rafter where the Inside of the Top plate touches.

Let me know any problem and I'm working in more options, just want to know how this goes, put some pictures for help.Also I'm working in a better Graphic User Interface
