Hi! Sorry for cross-posting, but this, being a reply to a message on the building-simulation list, may be of interest for subscribers of the general cad-linux-list, too. Draftsight works nicely, the only pitfall right now I have experienced is that the Linux beta is currently available only as a 32bit binary. Users may not be aware that they can use 32bit software on 64bit Linux installations, as most package managers will cancel the installation with a warning. I forced installation on my Ubuntu amd64 as such: sudo dpkg --force-architecture -i DraftSight.deb At the first try, this gave me warnings about missing dependencies, which could be solved by the standard package installation tools in Ubuntu. Than, the above command installed the DraftSight (32bit-)package from the Website, which is perfectly useful for people working on 2d drawings. Export of SVG makes it easy to transfer drawings into e.g. layout tools, and a PDF export options allows quick generation of documents for review by non-CAD folks. Cheers, Lars.
