Have you ever built a Guillows flying model airplane kit and wondered how they got balsa wood denser than most oak? On a guillows board a guy wrote that he was going to send a scathing letter to Guillows about their terrible wood selection and how it made models that can't fly. Someone else then posted they'd seen a framed letter at Guillows that was a scathing letter about the terrible wood selection, proudly displayed in the front office.
Sometimes I imagine that PTC headquarters has a room paneled in layers built up of user submittals hoping that some improvment in the basic functions could happen. Very thick layers. Perhaps this year's User conference will get to see that room in a behind-the-scenes tour.
