3D model/render/2D drawing/V carving (was Importing Jpeg Model for Vcarve)

Hi all,

I’m importing a JPEG file into model. It looks great at this point. When I select the Vcarve option in toolpath it does not show the image. I tried the Trace Image option, but the quality is nothing compared to the import option of model. I tried exporting the file as a PNG and reopen it in CC, in this way I could re-edit the image but couldn’t get the PNG to import to work properly. I would appreciate any assistance you can provide See attached

thanks John.

That is a pixel image, which shows light-dark so as to represent how the human eye would perceive a 3D surface when light from the right of the viewer.

V carving requires a 2D geometry outline from an SVG or DXF.

Normally the texture map import may be used to cut a height/depth map — but it would be necessary to arrive at such a depiction/modeling.

It might work to re-work the pixel image to get a height/depth map as discussed at:

As Will mentioned, the 3D model only works with 3D toolpaths.
The image you have is a 3D height map. Although it looks like a regular picture, it imports & carves well.

I imported the jpg & traced it. It takes a little finesse with the threshold slider to get a good outline, and it also traces some of the interior detail, but I just deleted all but the outline. Then I offset the outline to accommodate the radius of the 3D finish ball mill. Adv Vcarve the area around the bird, then 3D rough & finish just the bird within it’s outline.

I would disagree with that characterization — it’s a picture of a 3D model lit from the viewer’s right — when imported it does not re-create the original model as a height/depth map would.

You are correct. The heights don’t represent the actual model. But it does look OK carved.
Importing the actual model would be better.

Sorry guys I still don’t understand. 3D works OK, Trace Image works OK but there no way I can get that same level of detail or any detail for that matter when I import (Model) and use Vcarve…

Forgive us. Communication breakdown. (It’s always the same) :smiley:

You can’t Vcarve a 3D model. You need individual vectors for each detail.
Vcarve traces the tool between vectors & doesn’t even look at the 3D model.

That image looks like you might be able to trace it. It may take several traces at different thresholds & a little modification of the vectors & deleting duplicate vectors to get the detail you want.
Maybe a little manual drawing vectors where the shading doesn’t have sharp contrasting edges.

If you want this in 3D, why not buy the 3D model?

The big thing to understand here is that there are a couple of different ways for a design to be represented, and each may be machined in a different fashion, or used in a different way.

To begin, the original pixel image:

is a pixel image rendering of a bas-relief 3D design which is available commercially:

under a very specific license.

Contrast this with a 3D model of a bird:

which may be downloaded and opened in a 3D program:

(and also repaired if need be)

as a 3D model it could be imported into a 3D CAM tool and cut in the round:

(with suitable stock and fixturing and so forth)

If one rotated it it would be possible to get a bas-relief version which would look like to the rendering:

(coming full circle)

Interestingly, there is now a utility program specifically for this sort of thing:

(mentioned at: CC Pro - What do you want to make in 3D? - #16 by robgrz )

As noted, if one wants to do a V carving, one will want a 2D vector representation:

which once downloaded and converted and traced:

may be assigned a V carving toolpath:

Guys that you all your help I didn’t realize there was such a difference in jpeg’s. Your right there are multiple ways to get to your destination. Thanks again for all your help. John
