You would not want to do houseplans in Openscad. It has no provisions for making 2d views or projections, and no provision for dimension lines or text.
I use Openscad quite a bit for parts I will 3d print. Sometimes I create by basic part geometry in Openscad, the import it into Freecad (the only other tool that can use ,scad files) and apply fillets or other niceties that are difficult in Openscad. Freecad has python scripting, so you could "program" a part. It also has some capability for 2d views with dimensioning, although it is very much a work in progress. -- Ralph On Jun 27, 2017 11:54 PM, Erik Christiansen <[email protected]> wrote: Sorry for the late reply - just back from a week on the farm.

It is clearly much more powerful, as it handles 3D - very nice. (Assuming the "Open" means it runs on linux.) Fortunately, there's not a lot lost in this particular use case, as floorplans, elevations, sections, and site plan are all 2D. However, I have had to explicitly define variables, as described upthread, to automate transfer of e.g. truss length from floorplan to sectioned elevation. (So, yes, using Postscript is a hack.) Postscript is quite efficient, though, as I've produced 8 drawings with 798 lines of text. And there's a lot of detail in the floorplan, and a reasonable amount in the sections. The drawings are all done, except for some details on the site plan, so I've missed the boat for drawing it all in OpenSCAD. What I will do is look at that for 3D design, once I've built and the mill & lathe are in their new home. (Off-grid, solar powered, maybe with a 10 kWh Zinc-Bromine flow battery for filling in during clouds, and for evenings. Hopefully the price will diminish a little bit in the next 18 months. Down under, it's the northern roof plane which will carry the 6 to 7 kw PV array.)
