<DIV dir=ltr><FONT face=Arial size=2>You might want to look at DOE2.2 (equest).
You can now create polygons with 128 points which allows you to closely model a
circle. The program also has a Sunspace feature that makes it
easier to model atrium spaces. The program is free at
doe2.com.</FONT></DIV>

<DIV dir=ltr><FONT face=Arial size=2>I am not aware of a program that lets you
model a circular space without using flat sections.</FONT></DIV>

round-shape building<BR></FONT><BR></DIV>
<DIV>
<DIV>I am now working on a project to simulate the energy consumption of a
round-shape atrium. Does anyone know if there are any simulation tools that can
define such a shape? If no such tools, I guess that I have to approximate the
surface with flat segments.</DIV>

<DIV>Thanks</DIV>
