This second exercise shows off the solar radiations that
affetcs buildings.
Using my previous Vasari's file I deleted
the lower map and drew a big rectangle that I extruded.
I added to my building some details that may influence
the warm absorption of the solar's rays.
After that I detailed my building (MODEL TAB -> clicked SHOW
-> clicked on SET and chose the plane to draw over -> CREATE MASS
-> SOLID FORM or VOID FORM)
