I have looked at software like Sweet Home 3D, OpenPlan3D, and various cloud-based services that cost money. As nice as they look, they each have severe limitations – main the inability to create accurate measurements for walls. For example, Sweet Home 3D doesn’t give enough precision to create a wall with a 9/16 fraction. OpenPlan3D the field is disabled.
I would like to be able to build a 2D floor plan, but also be able to convert it into a 3D model that I can then add furniture to for interior decorating. I would prefer open source, but would settle for simply free to use.
This can be done in Blender.
Here’s a new addon specifically for floor plans, although it’s not needed. I haven’t used it, I think there are others.
Blender won’t be as easy to use as some purpose built app, but it can do anything you want. There’s also a huge library of pre-made furniture models in Blenderkit, which has a free and paid version.
Thank you. That looks very nice and viable. Bonus that it gives me an excuse to learn blender.
SweetHome 3D is free and made for this, there’s also a lot of assets available online for free.
It’s not precise enough. I can’t use 9/16th measurements, and that’s needed.
Switch to meters. Problem solved.
