Hi All,
Got the router mostly assembled and functional. Now I'm looking at CAD software. Years ago, in school we were trained in autocad. I haven't used any CAD packages in quite awhile.
My first project involves cutting ribs for a concentrating trough collector. The ribs must accurately follow a parabola for it's inner surface. I don't recall ever plotting an equation as part of my autocad training. Is this something that is done very often today? What packages would be best (& cheapest) for this sort of thing?
Any recommendations would be really appreciated......
