Dear Sirs,

is there any manual or something similar where I can study how does your library work?
I have downloaded your library to be used inside Basic4Android and I saw the impressive carachteristics that this library has.
I want to develop a simple app for Android tablets that permit me to draw and to display a Computer Room Data Center starting from the surface of the room, its height and eventual doors or windows inside of it and display it on a tablet. It can be happen that the room also has a false ceiling or a floor void. The main purpose of the app would be to display what could be the reality when you have one or more computer racks inside the room but also electrical plants or fire fighting gas plants or heating and ventilating plants.
Well. That's all.
I wait your suggestion and I take the occasion to congratulate with you for the wonderful project that you created.

with best regads,
Max
