Gunsmithing Raster to Vector help

[jonaddis84]

Im trying to draw up an adapter plate for a pachmayr butt pad. I scanned the image and am trying to convert it into something useful for CAD.

I got a free trial of a raster to vector software but it keeps drawing these tiny lines where the noise in the image is.

Can anyone help?

Here is the image file

Thanks

I think I got it. Converted it to EPS (Adobe Ill. File). PM me an email. I will send it to you.

Thanks

When I've done this in the past the best approach that I could make work was do let the software draw all the lines it wants, then manually clean it up in DXF form inside AutoCAD or whatever CAD program you're using.

The other approach that I've successfully used is to take the rasterized image, open in Photoshop, overlay bezier curves manually in a second layer, save that second layer to a new image file, save as a DXF, open in AutoCAD and make small changes as necessary.

Then open in GibbsCAM and create the cutter paths for engraving/contouring/etc.

Are you just looking for the outline and holes? I can outline it in illustrator for you.

Re: Raster to Vector help

For me:

Instead of attempting to clean up the image, I just used the general outside shape as a sort of template. Then I use arcs/splines/curves (whatever) to get all of my stuff generated. Save only those features and import it into a new drawing. This gets all the "dirt" out of your drawing and makes generating tool paths much easier. Don't forget to scale it! Jpg/vector/geometry conversions almost always goof the scale.

Another trick is to use a very fine pen/pencil and trace the outside onto paper. Photograph that and do the same. Much less clutter. Get your lighting spot on so that it minimizes the extra crap.

Good luck!
