I am working on a project with acrylic sheets. The acrylic sheets I am using are 3/8" and 1/4". It's a simple design and that's why I chose to try Project Cooper. It's a nice, simple, easy to use program that has all the functionality that I need. The reason I asked if the dimensions could be set to a lower scale was because when I was using the rectangle tool, the dimensions were actually showing up in 1/8th and 1/16th inch increments.
Thanks for the additional information and we're glad that Project Cooper is working for you. Your project sounds really interesting - please keep us in the loop on how things progress.
Unfortunately, the dimensions that are part of an object (like a rectangle for example) have a different precision value than the dimensions generated by the dimension tool. We're working on fixing this and are hoping to include this fix with our next product update.
