What do you know about the discipline of mechanical engineering's Pro/Engineer program? What are the names of three computer-aided design (CAD) programs?

Your capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone. The final product is intended to fly over rugged wilderness areas and look for small fires that should be monitored and potentially fought or contained. It is NOT intended to be used in large active fires. Your subteam's job is to design and build the support frame for the drone (e.g. the structure where the motors, propellers, guidance electronics and GPS, heat sensors, radio receiver and transmitter, etc. are attached) for the prototype. You have access to a machine shop with saws, lathes (for removing material by rotating it and using a cutting tool), drills and a facility with 3-D printers that can print a variety of plastics using fused deposition modeling (this is the technique where a polymer filament is melted and forced through a nozzle to build a structure layer by layer). You will be testing in a summer/fall timeframe so you expect temperatures…

What exactly does "MEEN" engineering stand for, and how does it function? I would appreciate it if you could give me a quick explanation of what it is and how it works so that I can better comprehend it.
