Have you ever wanted to rearrange you furniture and after moving things around you found things didn’t quite fit the way you wanted them to? This used to happen to me before, then I started using measuring tape and grid paper. There are computer programs like Visio but, they are meant for professionals and cost several hundred dollars.
Today I found Floorplanner and used it to rearrange my office. It was really simple to use, it gives you 3 projects and you can have multiple floors per project. All for the low, low price of $0. Signup for a free account and remember: measure twice, cut once.
