The BIM thing has been intriguing me lately. One of the other (!) software companies has been pushing their software to create BIM models, but having watched their videos, I felt that SU could do most of what was required,i.e. 1) a 3d model 2) able to render from the model 3) using 3d components 4) extracting component information for estimating. It was only the last item that I found a bit flaky. (I know that there are timelines and facilities management stages, but that isn't necessary for my domestic work)
For small, domestic projects a full-on BIM (using sophisticated layering conventions etc) seems way over the top, but it did occur to me that to assist the builder in pricing for the work, that I could lend a hand and extract areas and volumes of materials, lengths of beams etc, that a builder, without the benefit of the 3d model would otherwise have to prepare manually. The only danger is, me making an error!, so it does put the onus on me to double check the output. (most small builders don't have CAD software anyway, let alone a computer)
I've just given this a try out on my last project, preparing "QUANTITIES of Main Elements
(from model)" and with a hefty health warning about the data being to assist the builder etc. I will wait for feedback from the builder quoting for the work.
