Help needed for 2.5d carving

[Emmess (Matthias Solga)]

this project, done in 2d
queen.c2d (60 KB)

is the first attempt to re-do this set:

Need some tutoring how to make a semi 3d project. I think I saw it somewhere, but cannot find it.

(I talked to the artist who designed these pieces, and he gave me allowance to do so, if I succeed I will present him my result, and maybe he agrees to sell the items. Would make me proud, so far it is the nicest set of chess pieces, nicest design, I ever saw. It is Paul Joshua Schneider btw, chess — Paul Joshua)

These would pretty much want to be made by 3D modeling/cutting on a lathe/4th axis.

Import the SVG into Alibre Atom3D and Revolve it?

That said, you’ll pretty much want a 4th axis/lathe…

[WillAdams (William Adams (Carbide 3D))]

If you reduce the outline to half:

then save as an SVG, the SVG can be imported and rotate_extruded in OpenSCAD:

which can then be exported as an STL and then imported into Carbide Create Pro:

and cut as a 2-sided flip job using 3D toolpaths.

[WillAdams (William Adams (Carbide 3D))]

The Knight of course will require some 3D modeling/editing — perhaps use Blender on the STL?

Or model it completely using Alibre?

[WillAdams (William Adams (Carbide 3D))]

Or, go full-bore and draw it up in profile and do something along the lines of:

Making a base for a model

Given a prototype base: [image] How to make it in Carbide Create? First, we have a pixel image with some dimensions: [F-86 base scan with measurements] We import that into Carbide Create: [image] using “Set Background”: [image] and adjust for size: [image] [image] It’s then a matter of drawing and toolpaths and so forth (we will try to do it w/o Create Pro, but will also show that). For reference, there is an overhead view as well: [DSC00036]

Spoon Possible without CC Pro?

I’d like to make a wooden spoon and was wondering if that’s possible to do with the standard CC? Can it be done with a bowl bit? I don’t have one but can pick one up. Thanks!

You can get pretty darn close just using CC…

Notice the outline for the main body shape has to be extended to get a good round profile across the body. Then the ends are subtraced away, and the spheres at the top added using MAX merge type. The circle at the bottom/base I used to create a 150mm gage to insure the base was the right height.

[Emmess (Matthias Solga)]

Thanks! I’m having a bit of trouble to dive into 3d-construction and 3d CAD, it is another level than 2d CAD. Thanks for the workaround with the CC what I already use (would not dare to say I know it…)

Will keep you informed about my progress, but don’t expect it too soon.

William: yes, the lathe is what the designer uses. I never used one, and probably will need some years to achieve only half the perfection the lathe artists show. Will try to use the CNC machine w/o 4th axis. I am encoraged by projects like this https://www.etsy.com/listing/1165744843/scacchi-scacchi-cnc-scacchi-3d-file-di?ref=yr_purchases
and all the wonderful 3d projects with baby butt smooth surfaces on that site here, not the least is Kevin’s alligator door
