Dear All:

On my first use, I set up a sample project (.pd2 and .inp files
attached).

On re-opening file, I get a vtk output window with the ff:
ERROR: In E:\vtk2.3\Nightly\vtk\common\vtkPolygon.cxx, line 1172
vtkPolygon (0x11004B10): Possible triangulation failure

Then later on I get a window on BDL Errors on line 350.

Also: Site Parameters : Input must
include one space command
HVAC System : Input must
include one system command
Thermal Zone : Input must
include one zone command

What do these means and how do I fix?

Thanks, Andrew
