drawing board drawings to cad drawings
Trying to get a handle on this CAD stuff, I would like to produce a DXF cad drawing and using sheetcam get the G code for my machine .
I am attempting to copy a relatively complicated antique piece which involves many sweeping curves. I am a little long in the tooth so methods I am comfortable with are probably a little out of step with modern practice I was working on the board long before the advent of the PC and most other computers for that matter. So here is my procedure I am producing a drawing based on a photograph ,scaling each of the major components .When I have a reasonably similar scaled sketch I overlay it with ships curves and for the smaller details french curves. When this is completed I anticipate overlaying a grid on the drawing and read off the XandY coordinates and transfer these to produce a CAD drawing . A problem I may have is that sheetcam does not like splines and any splines would have to be converted to polylines. Most ship and french curves I believe are second degree curves so I am not sure if sheetcam will see them as that. any suggestions to simplify this precedure or answer the sheetcam recognition question would be appreciated. regards mike hide
