Tutorials: Architecture approaches

[mikeao]

Very good! I was asking myself the question: "can i do architectural models with Wiings3D?" just today and it is great you have posted up on this topic, just today.
One question from a complete novice ( i worked my way through a wings3d tutorial 2 years ago, my total 3D experience - and fun if i remember right - so here i am again ): what format was the technical/CAD drawing you imported into wings, DXF by any chance or an image?
Ok another one: can you work with units of measurements in wings? I am going to be doing a few simple cad drawings and would like to produce a few simple 3d models directly from them, just like in your tutorial.
