Have you attempted creating a doll room box, starting from the floor, to the walls, to the little furniture only to find out that they don't match, or the room is too small for the furniture? If only you can get an idea of how things will be laid out or if the colors scheme is to your liking, you'd be more confident in starting a room box project. Since not all of us have an experience in interior design, chances are, our room boxes doesn't end up they way we imagined it.
Now, there is a tool that can help us turn the imagination into a plan. By plan, I mean measurements, layout, and tested color scheme. You can try Planner5d and create a virtual room box in both 2D and 3D.
The site is so easy to use. You can use the metric or English measurement system. For my room, I used the English system so it will be easier for me to convert to the right doll size. Although you need a paid account to access all the items you can add into the room, the free account has enough items you can use to stand in for the actual item you intend to use in your room box. Like the window I used here, it won't be how my window will actually look. I just want the frame to be that size and in that color.
The size and color of the items can be modified. You can move in and around the room in 3D mode. The wall can be made invisible if it blocks your view, like the 4th wall here.
I've been learning more about making dollhouse stuff and I really want to make one. After making this virtual room box, I think I'm gonna go ahead and make one. Even if you are not going to make an actual room box, there's a good chance you'll still enjoy creating a virtual room.
