The usual path to designing a shed is either a paper sketch or a general-purpose CAD package built for machined parts. This project goes the other way: a browser-based CAD program that only speaks lumber, with the maker asking FreeCAD users whether that narrowed focus makes switching worthwhile for structural lumber projects.
The pedigree is strong. Development has run since 2020-22, on an earlier engine the maker built for the aluminum industry in 2010, one that has spent 15 years in production serving many thousands of customers in light-medium industry. A free beta opened on posting day. The sample design is a small wooden shed, built up step by step: four concrete deck blocks at the base, perimeter rim boards, evenly spaced floor joists, an OSB or plywood subfloor, then bottom plates and studs around the perimeter. Side walls carry sloping top plates for a single-slope roof, a birdsmouth cut is configured on one rafter before identical copies are spaced across the top, corrugated sheet metal roofing goes over the rafters, and the front door rough opening is framed with studs and a header. By the end, the shed stands framed, roofed and with a door opening.
The surrounding tooling stands out too: an existing parts catalog, so far limited to North American standard dimensional lumber with EU sizes such as 45x90mm coming soon, plus automated documentation producing cut lists and drawings. A bill of materials panel sits on the right, with lumber components and structural tools on the left and top toolbar. An array tool exists for duplicating components, though the maker prefers dragging joists manually.
The open gap: no structural FEM analysis, so it is not suitable for load analyses. A native SolidWorks export is in development because STEP alone will not suffice. And the license, open-source status and whether it is paid remain unanswered.
