  • Convert pictures to cad format... how?

    Or, more specifically, what program can be used to do so? Preferably, a freeware one... Thanks in advance.

    Just got my Sherline mill CNC'd... Yesterday I cut a letter. My wife, ever enthusiastic, said "And what will you do with a 'B'?"

    Ah, she just doesn't get it.

    Luckily, she tolerates it.

    Ben,

    Pictures of what? In what format?

      Various line drawings. They're in various formats (tiff, jpg, bmp), and I thought they'd be a nice basis for some engravings.

        For line drawings this is entirely doable. I don't know about freeware, when I have time I'll look for you. You need a program that will convert a raster image to vector. I use Corel OCR-Trace. It will accept a TIFF or other format and trace it to a vector format. It doesn't save to CAD format but it can save to HPGL and a variety of other formats that can be imported into a CAD program.

        You need the best possible starting images for good results.

            Ben,

            Here are some links to freeware tracers:

            Here is one for DOS that looks really interesting:

                You might like to try a search on a programme called 'Scan2Cad', it's got a 1 month trial period and was reviewed a few months back in M.E magazine where it got rave billing.

                We tried it at work and have been pretty pleased with it for doing electrical drawings.

                  My version 14 of AUTOCAD has a pcx input subroutine in it's drop down menu.

                  I had a pcx2dxf program years ago. It had one install, I went in with pctools and changed it to hexFF (255) where it would be now I don't have a clue..

                  It works great by the way.. I sometimes engrave, sometimes layout right on the steel. I paint the steel white, use the transfer paper I use tattooing with a iron. The Spirit thermal copy paper makes pretty durable blue lines you can then engrave or drill..

                  Any way I can help, just email me.. I have a box of the transfer paper, it is kinda hard for the normal person to find.. I am running wide open these days, answer email twice a day now.

                  YOu can do circuit boards the same way, etch them with the blue as the resist.
