So, I have this file, and I have this buddy that lives in Virginia. They have had this coin series, and he collected them. Now he sent me a request to carve him a wall hanging.
So, I have this file, and it is a PNG photo that I got from some official Virginia site. I never could find a digitized image.
So, I have this CC Pro free trial, and I imported this file (PNG) into it. It produces a 3D model, but of course it isn’t acceptable because this isn’t the proper PNG for that purpose.
Where do I go to convert this PNG file to a PNG file that is acceptable to CC Pro?
Thank you in advance.
CC Pro needs a heightmap image as input, so first it needs to be a grayscale image, but mostly it needs to accurately represent the high and lows in the image. So in 99% of the cases, a regular image/photo converted to grayscale won’t work, because chances are the lighting is such that highlights and shadows do not match the relief of the piece.
For a coin, you may be able to import that PNG image you have in Inkscape and auto-trace its features to get a set of 2D vectors/outlines of the coin features, and then you could import that in CC (non-Pro) and set flat heights yourself via toolpaths at multiple depths. But getting nice 3D curvy surfaces from a regular picture…not easy in the general case.
Can you share that image maybe for better advice ?
Nice coin. Unfortunately this is what I was talking about, there are highlights and shadows that do not match the expected height for things, and no easy way (that I know of) to make that into a 3D object, but someone else may know a trick.
I would maybe look at other options ?
- Photo V-carving it ? (If you have Vectric VCarve that is…)
- Make it a lithophane
- trace it in Inkscape and engrave this with a diamond drag bit on metal? It’s not going to be fun though, here’s the (poor) result that I got playing around for a few minutes, Inkscape gurus may be able to do much better
If I make it big enough, then vcarve will work. However it won’t look the same.
I’m afraid I’ll have to find a way to get a 3D scan of a real coin.
So, I’m looking around for a solution and came up with this STL file. However, I should notify @fenrus that his STL2PNG online program gives me an error code. Since the creation of the STL was so simple, I’m not surprised that the result has a problem, but perhaps its me again? I imagine it is a blank file.

Ah an ascii STL not binary STL…
different file format…
hold my coffee
realistically it’s going to take an hour or so to code this, maybe a bit more if family stuff interrupts so feel free to put it down
Hey, nobody is going to complain about that kind of service!
We are going to have to start an official “Hold My …” list. Thank you @fenrus for all of your hard work and willingness to share!
