FreeCAD’s Arch/BIM workbench
Draw in 2D to create 3D walls. Position windows, doors and others in 3D. Some features like the roof or stairs have their own modules.
You can always fall back to one of the other many workbenches should you need something not part of a typical home (weird stairs, a detailed cupboard, …).
I could not find documentation easily in the past but it likely exists. For a video introduction the FCBLounge channel (YouTube) provides great visual tutorials.
I’ve documented part of our home in this to ideate remodeling. It can be used for pipework but I did not try that yet.










There is a distinction between an app and a site. An application has many partial state updates. Two updates is uncommon for an app. Way different for a website where people ideally land on the right page from a search engine. There is a place for an SPA but it’s not everything.
We tend to stick with an SPA even for things which are mainly reads because we’re more efficient in a single tech stack. Sadly we don’t have big tech budgets to do everything. In theory the JS SPA backend can simply run in the backend if there’s no need for an SPA. I had thought hydration and caching to have gotten way better by now but there’s still a good way to go.
