Re: Generate roof plugin

1. Thanks for your willing to help.
2. Don't forget: there is all kind of irregular 3D polygons so I need an universal formula (preferably some java code)
3. The bad news: I've put in hold this plugin for around 8 months. I continue to fight with Stair Builder.
4. The good news: I'll think about this along the others when I'll have time.

Re: Generate roof plugin

Yes you are right. There must be a universal formula.

Of course, when you have time. Thank you for developing and sharing such a plugin.

Re: Generate roof plugin

Maybe it will help you find it...


In this code, the area of ​​each triangular surface of the 3D surface is calculated by Heron's formula.
This formula helps you find the area of ​​the surface with the side lengths of the given triangle.



Heron's Formula:


If the side lengths of a triangle are aa, bb and cc, the area AA is calculated as follows:

Here, ss is the half perimeter of the triangle and is calculated as follows:

Re: Generate roof plugin

Thanks! Could be useful BUT...
I need to input a 3D series of points (x.y.z) representing the irregular polygon boundary (supposing all points belongs to the same plane)
and something(formula or code, eventually java code) to compute the 3D polygon area.
So, please continue searching.
