I have been experimenting with the SAT export from 3dsmax 2010 a bit more and thought I'd share these images with you, haven't a clue what they are!!! :-) The following where formed by.... A Geosphere hemisphere created in 3dsmax 2010 > exported as a SAT > imported into Revit concept mass family > each face sub-divided > curtain pattern panel family added to each sub-divided face > loaded into project environment and rendered using Zach Krons soft shadow technic.
