Traverse-PC is easy to learn & use. It is common sense logical. I was able to create drawings after a couple hours instruction. The software produces quality drawings & the tech support, for questions regarding the ‘fine’ points in the learning curve, is excellent. The TPC people are open to suggestions to incorporate into future upgrades & really try to help you ‘get it done’ in a timely fashion. You will not be sorry you invested in this product.
