I am hoping someone here with experience can guide me. I have recently purchased a used Tormach 1100 series 3 with Path Pilot. What I am looking to purchase is software to design my own parts or implement those from plans I have purchased etc. I have been hand machining parts for a number of years and I am very green to the CNC world. Since I mostly making model engines what software is a good choice that is user friendly and can work with the Path Pilot. Maybe down the road possibly use to design and make Homebuilt aircraft parts. Any suggestions greatly appreciated.
