Since I got married and since we decided to stay in the current apartment for another year, I've been involved in a bunch of home improvement projects to neaten things up, clean some stuff out, re-organize, and build some furniture to make better use of space. I've finished a set of shelves to replace one of the desks I had. I'm in the process of building a small set of shelves to go above the counter to use some vertical space in the kitchen for storage. I'm thinking about building another set of shelves.
My brother-in-law uses Google Sketchup to do his drafting. I had a look at it a couple of days ago and what he's done with it and it's pretty wild. My problem, however, is that I'm running on Linux and I have a preference towards Free Software and Open Source. Partially because I'd like to share my plans with other people in non-proprietary formats and partially because I stand a better chance of fixing things when they go wrong.
Does anyone know of 3-d modeling/drafting/basic CAD software similar to Sketchup that works in Linux?
As a side note, it turns out I have the same estimation problems with home improvement projects that I have with programming projects. Irritating.
