Hello everyone, I have just recently joined the NAWCC, and this is my very first post on this forum. I am just starting out in clock construction, and my goal in future is to construct skeleton clocks in traditional materials such as brass and steel. My primary interest is in skeleton table clocks, with fusee and power maintaining devices, etc. My question to forum members is; Can any of you recommend a specific CAD program which is well suited for clock construction? I would like to be able to produce scale drawings for the purpose of producing paper templates, make renderings and simulations, etc, however, I do not necessarily require a program capable of creating tool pathing, as my intention is to machine all the components using a lathe and vertical mill, etc (no CNC). Ideally, I would like the possibility of creating cycloidal tooth profiles that match commercially available gear cutters for teeth and pinions (perhaps some CAD programs even provide this feature?) From what I have seen from different web articles, Autodesk Fusion 360, Autodesk Inventor, Rhino for Mac, Medusa 4 Personal, KeyCreator 3D and TurboCad Professional V6, appear to be suitable for designing mechanical clocks, however, I do not know enough about CAD to be able to determine which program is best suited. Can anyone give me their recommendations, and if you have personal experience with several CAD programs, but have a preference for one program over the others, would you be kind enough to share your reasons? Any advice would be greatly appreciated, as this is a completely new field for me. Best wishes, Paul.
