Thanks for the advice, but it's not quite what I was hoping for. I can't find some of the patterns I am looking for on the Mosa site, so that won't work for me. I guess I have to make my own image file using SketchUp, Photoshop, etc.
$500 is a bit steep for a DIY software package meant for figuring out home design details, so I imagined it would have a highly customizable tile/flooring layout tool to let you create a pattern with different size tiles, set grout thickness/color, add border tiles, etc. That's a bit disappointing. It sounds like you can't even do this in Chief Architect?
