it is very simple and you can use it very easy. when i enter website, i like this design, but soft is very old interface.

I like that you are able to creat custom items and determine which ones will work best for your. You can see it without having to take hours or days to create on a piece of paper. It lets you save your work and compare what will work best for you. You can view it in depth with the right measurements before you continue your project and see how it will work in a 3d dimension. Pretty awesome software. It has helped me a lot and I hope it will help you as well.

Sometimes rather than trying to work things out in the field, it is easier to problem solve on the computer and detect any clashes using software like SketchList 3D
