    I see Scott.
    I have confirmed that it is only with V8 that some 3-d abilities kick in.
    Upgrading will be up to the machine owner.
    Back to original request from Ace:
    What software are you using to create your 3-d curves? If you can create the base shape without the waves cut into it and import it, as for example an STL, then you can create the vectors for the waves and machine onto the model in Vcarve Pro 8.xx by projecting the toolpaths needed onto the imported model by checking the "project toolpath onto 3-d model box but not earlier versions.

    Dave,
    Forgive the quick putz, but didn't use 3D at all. all fluting toolpath.
    Can send file if you email me.
    Just a down and dirty concept cut. Needs tweaking, but it's kind of close.
    Hopefully pics help?
    Drawn in VCP8 though so don't think you can read it?

    Looks like that could be it but hard to tell as your pics don't end up very large when opened.
    Can you save/post them in larger dimensions?
    I think Ace needs them more than me!

    Lets try again Aaron,
    If you want file, my e-mail is in my contact info.
    By the time I looked at pics on thread, I'd hit the 20 minute mark.

    Ah-So it's that smooth button.
    Can you figure out what kind of numbers to input to make it concave? (Just for the hell of it)

    Yup, but only works easily with concave....It won't eat -#'s. Closest Vectric forum has come is a linear array of VERY close lines and then working in pairs of lines offset from center line, and then toolpath gradually deeper with some math thrown in....MAJOR PITA!
    If we bought a true trough, rather than this dome I stretched and then trimmed with a bounding box and cut on selected vectors, we could come close, but it still wouldn't be accurate. We COULD profile with the BN on the line, and interesting things could happen, but not what Aaron was doing.
    Hope this made sense. Glad I tried cookie cutting the 3D, hadn't tried that before.

    Hi Guys,

    I apologize for the slow response, but thank you so much for all the effort put into replies here!

    To answer some various questions:

    I am working in Rhino and can easily output the geometry without the ripples inside. I can also output the vectors I have and import them easily.

    I will be back in the shop on Tuesday and I will experiment with both project curve to geometry as well as smooth ramping on a flute cut.

    I'll double check which VCarve is loaded up, but I think it's the 8th edition and I'm fairly certain I've seen the project curve option.

    On Flute cut if you make a pair and alternate Start Points/Group/ and THEN linear array it saves a lot of air time,But then you get the alternating climb/conventional cut thing going on.
    Just mentioning.
