But thanks again for your help.

    do you think turning down the resolution on the scan would help any?
    Hi Vince,
    Turning down the resolution on the scan will not help. You never said what your end goal is with Joseph. Is this simply to learn how to convert bitmaps to vectors, or are you planning to engrave, route, or cut this shape on a cnc router, vinyl cutter, etc? There can be quite a difference between the result of a "quick & dirty" manual trace and that of a more detailed/accurate manual trace. It depends on how closely you want your final part to match the original. In any case, there are several techniques which you could employ to improve the quality of your bitmap image so that auto-tracing becomes practical.

    Step 1 - Use a pen as you originally did to trace around your original onto a piece of dark colored paper.
    Step 2 - With a sharp pair of scissors, cut along your traced line to produce a "template" of the original.
    Step 3 - Scan your "template" to produce a bitmap file - as you originally did. If the "template" is too large to fit your scanner, place your "template" on top of a large white piece of paper (for contrasting background) and take a photo with your camera.
    Step 4 - Import your bitmap file to VCarve Pro and auto-trace.
    Step 5 - Edit as required.

    I followed steps 1-3 above and here is the result of the scan.

    Here it is imported to VCarve Pro.

    Here are steps 1-3 but with the "template" photographed instead of scanned.

    I used Paint.net to crop photo.

    When using "trace bitmap" for photos, it can be helpful to increase the noise filter setting from the default to around 8-10 pixels.

    Vince - here are the resulting dxf files from the "trace bitmap" operations above.

    David,
    I like your idea for cutting out the outline. I'm going to profile cut the piece from wood. Precision is not that important as it is supposed to be rustic.

    I did some tracing but obviously I did something wrong. I know I need to trace on the bitmap layer but should Layer 1 be on as well. I don't why I got the offset. See attachment.

    Hi Vince,
    Are you using the "Trace Bitmap" command here, or are you manually tracing? Perhaps you could post the jpeg/bitmap file your are importing to VCarve Pro for your trace. Here is the scanned file I used for the auto-trace. You could try it with this one to see if it makes any difference. I will send you a PM.

    I thought I was following your instructions. I set up the snap options as suggested. It seemed to be going well. Here is the bitmap and the crv files.Thanks again for staying with me. I used the draw curves command not trace bitmap.

    Hi Vince,
    I am not able to open files from the trail version of VCarve Pro. So all I have to go by is your Mary jpeg. Here is my manual trace.

    And here is the quick engrave.

    That's odd. Did you open the Joseph crv? Try this one.

    anyway, what did I do wrong? Could you tell?

    I can't open this one either. Here is the error message.
    trial version.jpg
    Also you are using trial version 10, and I have version 9.5. Older versions apparently cannot open files created on a newer version.
    I don't know what you are doing wrong. I have sent you a Private Message with my email address. Please email me and we can exchange screen shots to figure out what your problem is.
    Thanks,
    David

    Trial versions cant open anything. And non trial versions can't open anything coming from a trial version. That's so somebody can't generate some vectors shipped somebody with a full version and get a viable workable file back.

    Mark is correct. Files from any Vectric trial version are not "cuttable" nor can they be transferred to a licensed version.

    To my knowledge they are not only "not cuttable" but you cant even open them (hence his screen shot)

    That is false if you create a file in a trail version and then buy the a licensed version of it it will open as loand as the trial was created on the same computer.

    We are referencing someone sending a file from a trial version to a licensed copy holder or vice versa. The OP posted a file from a trial version. No one with a paid copy will be able to open the file and ship it back to him or the other way around. Its pretty much a given that when you fork over your cash you will be able to "use" the work you created in the trial version. Thats just basic math.

    To clarify, I meant not cuttable with the trial software, if I'm not mistaken. Sorry I wasn't clear.
