Sorry for the late reply - just back from a week on the farm. (Soil test done, so foundation & slab design can now go ahead.)

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.)
