Hi Kevin,
As much as "Auto CAD" hates it when professional designers suggest this...the lion share of CAD work today is being done by
Sketchup.
They are an "open source" (not closed and proprietary entity like Auto CAD and others) and even the "professional" version is about 1/5 to 1/10 the price of what was considered "professional versions." This has...in certain circles...becomes a very heated debate (attached to money of
course.) I support any company that supports "open sharing" and free education to schools and training programs...like Sketchup does.
Does it have all the "bells and whistles" of "Auto CAD?" Well not yet... (But that changes about every six months as Sketchup gains ground) however, I don't use those "bells and whistles" anyway. I sure don't need to drop $7K for them...that's for sure...compared to free or $500 for the pro version.
I have, in recent years come up against some very large architectural firms, and they would have cost many of these projects the minimum of $30,000 on average...while still requiring their drawings to get PE approval. So the
Project Managers would of course ask...if a designers fee is a fraction of that, and both entities have to still get PE approval...why hire an architect? It boiled down to a degree and
experience. More and more, the "design-build companies" (especially in historical timber framing) are pushing Architects out, or to at least charge more realistic fees, and/or "team up" with design builders.
So, over all, I would say try Sketchup. You get great support, and it is a "self-paced" learning curve that is not that difficult to master.
Good Luck,
j
