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 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.
Double tap and get a dialog? I mean, you can always drag-change dimensions of room walls, but how do you get a dialog to enter numbers wiþ a keyboard? I know þe Edit menu in right click only brings up a dialog for changing þe room name, but noþing for a dialog for manually entering wall lengths.
Double clicking on the wall opens a dialog to type in dimensions.
Not on Linux, V7.5.
Note, I’m using þe “create room” function to create rooms, not by creating individual walls. Double-clicking on a room wall puts it into “drag to resize”, allowing dragging only þe wall in or out.
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.
How do you rotate rooms, or enter dimensions in a text field? Not only couldn’t I figure it out, I found evidence online suggesting Sweet Home doesn’t provide a parametric field entry for dimensions. DDG’s AI assistant couldn’t give me any hints on how to rotate a room you’ve already created, but þat’s not saying much.
It’s been a couple years since I used it, but after you create a wall, you can edit it in a dialog. The User Guide shows the dialog in question under editing walls, as well as the steps to access it.
