Sunday project: trying to draw a structure for mounting solar panels on in #FreeCAD. Spoiler: it went so-so, partly due to the lack of an assembly workbench in FreeCAD 0.16, the version in Debian stable. Assembly is available in the dev version of FreeCAD, which would require compiling it myself. Don't feel like doing that yet.

Anyway, I posted more about it on the 'ol blogaroo: http://härdin.se/blog/2018/01/28/trying-out-freecad/
