When using AutoCAD Architecture 2009 you'll want to maintain a consistent setting for OSNAPZ when tracing non-coplanar lines as you turn them into walls. Take a look at the graphic shown below for an example of what can happen under different conditions.
- The walls drawn on the left side are drawn when the view orientation is set to top. OSNAPZ is set to zero.
- The walls shown right are drawn based on a copy of the same underlying linework, but OSNAPZ is set to 1.
- The walls shown immediately on the right under each group use the "Apply tool to linework" option from the walls tool on the design palette. Note: This tool doesn't care what the OSNAPZ variable is set to. It seems to default to OSNAPZ = zero.
Three different results from the same tool. It always comes down to consistent user interaction. Be aware of how the software works and you can fix these problems easily. Download the ACD2009 version of my VBA macro for fixing non-planar walls here: ACA2009_Walls2_CommonPlane.dvb
Note: OSNAPZ variable had no effect when using the "Apply tool to linework" tool.

It sounds really easy! I've included the step-by-step guide to using IES’s VE-Ware as published in the news release:
- Insert geometry data
- Tell it where your building is in the world
- Define your: building type construction materials heating and cooling system types room types
- Press a button – automatic detailed thermal simulation is performed for you
- Get output on: energy consumption CO2 emissions US benchmark against the 2030 Challenge
- You can then easily modify your building and assess different options
IES’s VE-Ware, which is available to download for free online, gives
limited but incredibly valuable access to its world leading
Apache thermal analysis software. New and existing buildings can
now have their energy and carbon emissions easily assessed for free.
