@Daniele,
Thanks but there is few problems:
1. Wrong texture;
2. Use full power of CampSkeleton.

1. I don't know how to make texture to be correct rendered.
It is a lot of terms and ordered sequences which I don't know.
I still try but I don't see a good result without help.
There are people who (I suppose) could do this (@enkoniyto, @ndorigatti) and maybe others.

2. Implement:
-2.1 Individual faces angle but for this I need:
--- to be able to select face in preview (similar to texture manager) but with mouse;
--- to add a slider for selected face, synchronized with an input box for precise value;
--- to add an reset button (to 45dg) for all faces.
--- to implement dynamic roof generation in moment You move slider or insert value.
--- I prefer a Model Preview Controller (like in main software) than to rewrite it again.
-2.2 Compute polygons with holes (like B or 8 or D)
--- for this could be selected more than 1 room but with smaller area than exterior roof projection and with all points inside projection.
--- first must verify IF CampSkeleton really can compute this. There is a file for this but I don't know if and how it work.

The most important and urget (for me) is 1.

Do You like my dreams?
