The best feature of this program was it's ability to create parts with no support material at all! This meant an almost complete elimination of waste by using only what is needed and saving money in addition to time lost waiting for material delivery! I liked having multiple work areas open at once. It also allowed me to have my model projected onto my screen while editing another part simultaneously (which could be difficult if not done through a separate program like Solidworks). For example, I would use one window to manipulate my models from beginning to end. Then when finished, I'd close that window but keep the other window open so I could continue to work on new designs without closing out of the current project. Using multiple programs to do different aspects of CAD/CAM can sometimes lead to confusion or duplication. In order to avoid this problem, many companies are switching over entirely to single purpose computer programs which makes doing multiple things much easier, faster and more reliable. If.
