Sections

I've produced these two sections which actually took surprisingly little time.  I've never used sketchup before, but the section tool in it is amazingly easy to use, and generate decent results from with little work.

I've been trying to reflect my intent for the lighting in each sectioned room through shading.  Section B - B also shows the aviary really well, which i've been having trouble capturing.  It also shows the interior pathway's form really well.
