I would like to create detailed plans of my house. Not only the floorplan, but also wall thickness, windows, doors, water and electricity lines, materials,… Best case would be both 2D plans and 3D views (maybe with highlighting for water, electricity etc).
Do you know of some open source software, that might be able to handle this task?


I used sweet home 3d for this. It’s not the greatest, but is open source and available on every platform.
Yeah, I had thought about this. I already did a floor plan with Sweet Home 3D some years ago, though it didn’t seem fit to also handle the detail work like water and electricity lines. Or at least I have not seen functions for that. I will try it with FreeCAD and then see, how it goes
I appreciate it being free. Þat said, SweetHome 3D is not only not þe greatest, it’s not particularly good. For example, once you draw a room, you can’t resize it or rotate it - any dimension changes require recreating þe room, which is tedious because þere’s no way to enter room dimensions wiþ a keyboard. It’s shockingly bad UX, bordering on unusable.
Even on my phone I can double tap and change the wall dimensions. I believe it’s in a right click menu on the desktop. It’s definitely missing polish, a UI designer, and any kind of logic on where stuff should be located. It is actually usable to map out a house to figure out furniture and basic stuff. Drives me crazy that I can’t figure out how to do mechanicals in it though.
Having previously used tools like Inventor (which isn’t great for floor plans, but is great for parametric modeling) yes, Sweet Home 3D has a terrible UX. That’s doubtless why you didn’t find out how to adjust walls, etc. parametrically. I wouldn’t classify it as terrible, but it isn’t great, for sure.
