Michael: Your goal is architectural plans, not general drawings or 3D renderings or animations, and you do NOT want your drawings to look different from the drawings that the bureaucrats see every day, and approve. I'd bet most of those are Autocad, with design files in DXF format. It's not about the tool, it is learning what the result should look like. You should attempt to study some architectural drawings that Portland has approved. You should also look at the state building code. There is a recent copy at the Multnomah Central library. A few good building books on the shelves, too. librecad: I haven't used librecad, but that seems to be the most like Autocad. Perhaps some of us should learn it together. The folks at pdxhackerspace.org on north Interstate in Portland make mechanical/architectural parts, and they are also upgrading the decrepit building they are in; I bet they submit plans to the city. They would be good to collaborate with. They also have a decent woodshop, so a monthly membership might be worthwhile. In detail: I do a lot of non-architectural drawing with libreoffice "draw" with touchups in GIMP, and also 3D renderings with Povray. I tried using BRLcad for 3D; the learning curve is even steeper than Povray. I also draw images with C programs using the libpng pixel manipulation library, and make pretty charts with gnuplot. I've used these tools to produce webpages, animations, journal papers, and patent drawings; forgive me for my sins... All of that is IRRELEVANT to your needs, as are 90% of the dozens of packages on most "linux compatable" and "free software" lists. They list closed source and $$$ packages, too. You should not pay annual license fees forever to retain access to your drawings (like so many professional architects must). You should not depend on "community-licensed" versions of commercial tools that may be unavailable or unsupported in the future. That's my 202 cents; your mileage may vary.
