Firstly I have to confess that I do not know if my idea is slilly or not.
I have created an area feature. this area feature has perimeter and enclosed_ area.
Is it possible to add volume to a this area feature, manually?
I have already got to add a volumen to my object. I have add elevation to each vertex
In the 3D View I can see how my polygon has volumen, but it not has floor. This means that the figure has fours walls and one roof. There is not floor.
Now, I have to export my polygon to FBX.
When I export my object to FBX the object that it has created is tottally flat.
