How to Draw a Floorplan and get a 3D picture with SweetHome3D

IMPORTANT LINKS:

This is Home Automation. We’re dealing with a bunch of connected devices in our homes. So it makes sense that one very useful way to interact with those devices is by looking at a picture of the floorplan. The software that I’ve been using for my floorplans is called SweetHome3D. Here’s my simple explanation of how to use it to make nice looking 3d images for your smart home interface.

Sweethome3d is free and available for the major operating systems and there is also an online version.

This won’t be a full tutorial of all the features available in Sweet Home 3D, and that’s because I’m not a SH3d expert. I’ll show you just enough to make a good looking 3d model of your house suitable for framing or for use with Home Assistant.

Steps:
Start with a sketch or image of your floor plan. Rough or estimated dimensions are good enough.
Draw the walls. You can edit the height or width of walls too, if you want to be more accurate.
Add doors, windows and stairs. You can adjust the size and rotation. You can import more styles if you really want to try and match your house.
Create rooms. You aren’t really drawing anything new in this step, just defining rooms so you can add things like floor and wall colors and textures.
Edit rooms by adding floors and walls. I feel like the selection here is a little limited, but there are probably easy ways to add more types of carpet etc, I just haven’t taken the time to figure out how.
Add lighting. If you want to use the higher end rendering feature then you’ll need to add lighting. It looks really good when you render with the lights, and you can change the image based on the state of the lights (on or off).
Add any more furniture or decorations you want.
Use the Camera icon to render and save a png image of the 3d model. You can adjust the view angle to get exactly what you like.

That’s how I use it for Lovelace. If you’re using it for HA-Floorplan then you can also save as SVG and assign properties to the elements. I haven’t done that, so I don’t know much more about it, except that it’s possible.

That’s it. Now you’ve got a beautiful floorplan ready for your HA interface.

To the point, quick, witty with no time wasting long winded comment. Accurate and informative. Great video. Thanks

Subscribed jsut because of the head. I watch lots of instructional/educational vids across all topics in Youtube and this is the only one with a talking severed head. Perfection.

A tutorial for next step for HA-Floorplan would be awesome ...please consider make one

[lachimolalart]

This is very helpful to a beginner like me! It's simple & straight to the point! Hopefully I can easily follow this once I start to actually use the software already. Thank you for this!

In .au an old outdoor toilet (pretty rare these days) is called a thunderbox, still used for indoor WC (water closet) but these days :)

Thanks for sharing this very useful package, look forward to using it with the HA interface! Thanks again

I thought I had already seen bad videos. But this one tops everything I have ever seen

[philippinesboxingandufcupd]

very informative video and not boring to watch

Great video, thanks for sharing. The Aussie name for toilet is dunny.

If you create walls first, double clicking when creating rooms will make the entire walled in area a room. Time saving tip.

I might be jumping the gun but, have you made the second video to intergrate this into home assistant? This program is awesome!! By the way!

[ZephonEx]

Hi guys is there a part 2 of this video? Thanks

[randylust]

Well done, got me well on my way, at 1:00 am :)

Hey DrZzs, great vids, big fan...
Do you advise using Sweethome 3D or inkscape? i saw both vids and went with sweethome(since its pretty easy), but then realized that there is no vid from you on the next step integrating the floorplan from sweethome with Hass.
Could you kindly do one please or advise what needs to be done to have it integrated with objects like you did with inkscape.
Thank you

is it possible to add distance/width measurements and angle measurements to the 3D view? I have not found such a feature.

I'm still getting used to the whole floaty head thing.. It remains a bit creepy :P

[johnsonguitarsongtutorials]

Hi good video, only problem is when drawing a house plan there are many measurements involved. Drawing outer walls no problem. Then coming to the inner walls where thickness already differs. Show your viewers where to change thickness of inner walls. Also the various measurements of the rooms, how to measure say a 250 cm size from the outer wall or a 100cm for passage, or a 300cm from opposite side. Ie how to measure the width to start an interior wall. I e tried the poly line way as a construction line or even the dimension way. Is there an X Y way to use. Please help. Thanks anyway.
