First off, I'm a total novice when it comes to CAD software, and this software seems to have been written by experienced users for experienced users. I had hoped this book might enable me to learn how to use conFusion so I could better utilize my 3D printer, I was mistaken. I was hoping that the author would have taken me step by step through the building of something simple, like a rectangle. She had me confused so quickly, I gave up. I use Tinkercad but wanted something more advanced and had hoped this was it, it wasn't. Look around, if you are a novice there has to be something better, I hope.
