Need Help!- Trying to design 3d geometry in V22

[cncjunky]

Someone asked me if I could mill cut a 3d dog head. Right now I'm playing around with v22 lines and splines trying to get them to make up the shapes of a dog face. Is there anyone out there that does this that could give me some guidance. Is there a easier way of doing or what? It seems like it's going to take alot of time to do it the way I am doing it. Is there a better program I could use in conjunction with v22 that would make it easier ?

Did you get "BobArt" with your V22 purchase? This would work nice for this.

[cncjunky]

Yes, v22 did come with bob art and I also bought that I have'nt even used or know if I even need because of the bobart that came with v22 and that is Bobart Xpro / BobNEst ver.3.0

[BurrMan]

Yeah, the Xpro will do essentially the same as I will show here. I dont have that one so its hard for me to walk you through it. My brother has it as thats what came with V21. At least look and see if you can figure it out.

I just went and got this picture from the internet, then I used BobArt to create an emboss that I could toolpath.

THe diff in the newer ones are good. If you find it does what your looking for, you would most likly want to upgrade.

Just to answer your first question, if you want to design the dog in 3d, this would be possible, but a sofisticated task. If you want the dog to be a custom dog, you could probably make a cool unique head. If you need it to look like a real dog, that kind of surfacing may be beyond V22 toolset.

Here's my goofy dog.

[cncjunky]

It's the 3d one that I am trying to do, yours looks like what I am trying to do. How did you put that dog head of yours together?

[cncjunky]

I thought you could attach to a 3d part a 3d engrave, that could engrave in all the final details?

Heres a file. You are running V22 right?

[BurrMan]

Make the curves layer visible and active and hide the cad layer.



Revolve -180 using "pick axis" and pick centerline.



Use surface 4 edges to do the neck (hide the first one create to do the same on the second side) Stitch all together.



Extrude tongue .5 inches to go through two curves.



translate 2 curves -y .5 inches, then switch ucs to front view and extrude 1 inches with the Z dir selected.



Switch to side view and extrude eyes as deep into head as you want.



Bool eyes out of head. Bool tongue with 2 surfaces, then unstich and get rid of surfaces that dont want and re-stitch. Translate into mouth.

I'm not quite sure what your asking. V23 has a new feature which allows you to "emboss from surface". So you could make a head like this then emboss the previous dog surface I showed onto this cad model. Is that what your saying? I dont think "engrave" is the toolpath for either of these.

Plus, the ears are seperate pieces. you would want to seperate these and cut and assemble afterwards.

[BurrMan]

You could spend a bit of time to make him look pretty good. FOr instance, the eye's are pretty odd. Here I just revolved half of one of the existing Eye curves and moved them into place and booled them on. Much better but still a bit cheesy! With a little effort on your construction curves, some nice eye's. A nose would be cool too. Just draw a "half profile" of a knob shape then revolve it and sink it into the nose and bool it on. Poke a couple holes and he'd look pretty good.
