  1. Re: Looking for a 3D Scanner for Gemstones

    I have never tried that, but I don't think I'll be able to keep distilled water clean in my current environment.
    It would be an interesting experiment, for sure.

    However, my superiors have tasked...
  2. Looking for a 3D Scanner for Gemstones

    Good morning, guys.

    I'm a CAD Designer and we already have a NextEngine Scanner.
    This scanner is pretty great, but runs into issues when scanning reflective/refractive objects.

    Alternatives to PEPS Fabrication

    Good afternoon,

    My workplace purchased a CNC LASER-Cutting machine from Germany, from SiroLasertec.
    The AC-300F. It is a 3000W LASER-Cutter.

    I have no real issues with the LASER-cutter...

    Re: LASER Cutting 24K Gold Sheet

    We have not tried freezing. I do not think we can do that at this time.
    Not that we can afford another machine, but what are the drawbacks of waterjet? Is there imprecision in the cut? Is it...

    Re: LASER Cutting 24K Gold Sheet

    It has a vacuum but I'm not sure it has an actual air nozzle to blow away material as it's being cut.
    I will check tomorrow if we have cut aluminum sheets or if they provided a setting for it.

    Re: LASER Cutting 24K Gold Sheet

    The Suppliers came from Germany and developed a setting that actually does cut, but it has a lot of issues:
    1. The splashback of the Gold gets into the nozzle.
    2. We had to move the nozzle about...

    LASER Cutting 24K Gold Sheet

    Our company just got a LASER Cutter from SiroLasertec.

    It's got a number of settings, but even when the tech guy was here, he couldn't figure out a setting for cutting through 1.5mm of 24K Gold....

    Re: Solid union

    Cut your pipe using "Wirecut" into two pipes such that the overlapping sections belong to two different polysurfaces.
    You can also use an isocurve ("Extract Isocurve" and toggle the U/V to get the...
  11. Re: What am i doing wrong - image size corel to lasercut ?

    Hmm... while I'm not a LaserCut user, I think I see the issue you're having.
    The issue is, the Multi-Image photograph is being saved such that the 'white' in the picture crops out, either via an...

    Re: Boolean operation on STL files

    In order to do boolean operations on STL files, you have to convert your other object into a Mesh, as STL files are imported as meshes, not as NURBS surfaces/solids.

    Re: How to close this geometry?

    You can also use the Dupedge (Duplicate Edges) command to create a curve for that open edge if you don't have it.
    Split the resulting curve vertically using that vertical staple-looking line.

  18. Re: Using LASER Engraving to remove plastic coating over steel

    However, it takes more passes than normal to clear off the plastic.
    Follow that up with a nice Steel-friendly engraving for a White Finish. Looks great, but there are different...
  19. Using LASER Engraving to remove plastic coating over steel

    Hey guys,

    As the title says, I'm having some issues using my 20W Fiber LASER Engraver to engrave a logo on plastic-coated steel (the item is a piece of eyewear- a colored eyeglasses arm).

    Well, if I were tasked to design that using only Rhino, there are a few ways I could go about it, but the best would probably be Network Surfaces, or...
  22. Re: 3D to 2D Polylines...are it is necessary to do this conversion?

    Glad you got some knowledge out of this.

    It's likely that the conversion program, whatever that may be, took the simple splines, and converted them into many many polylines. I've had this happen...

    Rhino V3, V4, V5 user, here.

    Forgive my ignorance, but what do you guys mean by "2.5D"?

  24. Re: 3D to 2D Polylines...are it is necessary to do this conversion?

    I went and loaded the SHADOW TEST.dxf that you attached.
    I don't see any 3D polylines that would cause a problem (everything looks 2D and, as you pointed out, all z coordinates are set to 0)

    Here's a piece of brass I had lying around at work.
    It's a dirty engraving (no cleaning pass afterwards, sorry!).
    The piece is only 0.75mm thick.

    So yes, it is totally possible.
