Which program is for setup planning?

SketchUp is another alternative program, but I have never dealt with it.

Thanks for the tip, I will also take a look at Sweet Home 3D.

I am currently working with RoomSketcher. It is okay in terms of usability and relatively easy. What bothers me a bit is the limited selection of furniture (At least they have some Hemnes, but no Ivar, for example, generally little from Ikea). And in some places, they try to sell a premium version more often. Otherwise, you can get quite far with it.

I have also looked at SketchUp. But it is complex and probably not for laypeople who have not dealt with 3D modeling yet. I found the operation horrible, I can’t get along with it at all, and that as a computer scientist.
