Hi Duke, one other thing that I should mention, you may be interested in several of the new things for v2, there is a summary of the new stuff so far here: http://kyticka.webzdarma.cz/3d/moi/doc/V2releasenotes.html .

That includes several things of interest to architects, such as Feet & inches units (for the US), and SAT format export to enable exporting curved surface data into Revit.

Also some of the new drawing tools that let you draw directly on surfaces, similar to SketchUp in some aspects.
