keep us posted to your progress i would like to see the finished project. my senior year at georgia southern we had to draw a engine in pro engineer (4-5) months of class work and extra help and sessions with the teacher. each team or group had a different part of the engine. the last week of school the professor uploaded all of our parts after he corrected somethings and fixed the drawings to spec. he put them on his computer and assembled the parts and aligned them to each other and then got the parts to move and the engine started turning and you could see all the forces acting on the engine. the program also told you expected life cycle, oper. temp., torque, h.p., it was incredible.
