So yes, I'm a few days late, but here's some pics of me cutting my first prototype neck.  There's a few tool paths that still need some cleaning up (you can see that big chipout on the bass side of the headstock but it actually came out pretty well.

The headstock angle on the front hasn't been cut yet because I still have to make a jig for the table so - no sense really in doing it on the CNC when you can do it in two seconds on the table saw.

Now I have to make prints so that customers can spec out the neck, make a jig to cut the headstock and a jig to rout the tenon or dovetail and make permanent vacuum fixturing for the CNC (what you see here is just double sided taped to a piece of MDF with a few alignment holes in it.

Here is my modeled midsole! had to do it with a series of trims and using the gumball to extrude a solid surface.  Ill bring it into SW to do the detail work of the cutaways and tread pattern.

Yes, in the project curve feature there is a option to project a curve onto another curve.

Anybody know a good way of making this surface a solid? I am just trying to cap the ends.

So after many hours of trying to solid up this loft 2 rails I am still nowhere close to getting it as a solid.  I was thinking of overbuilding the surfaces and trimming them away, but it seems like there has to be a way to get this fairly clean and still able to edit it.

hahaha ok fiiine. Had to ask! I'll think about getting that design drawn up tho... would be wicked to have my own custom axe!

I am trying to get an organic-ish tapper to the nose piece in solidworks, any good ideas out there? Bevel doesn't seem to work, it wont let me do a multiple radius.

Hi Jack, This could be best achieved by using the 'free form' feature look under surfacing. However to use this feature you would need to start with a single face. Alternatively using variable radius fillets may do the trick. good luck!

What is everybody's computer setup?  I am running a Xeon 6-core with 32gb of ram, but it seems like its still slow with the rendering.  anybody using a dual processor system?  I have a Quadro graphics card, but why doesn't keyshot and the other 3d programs use it?

I was reading recently that Keyshot is designed to use the CPU and does not actually take advantage of a GPU like traditional rendering programs. Please keep in mind, your classification of 'slow' depends on several factors. i.e no. of materials, geometry, reflections, illumination, output size, resolution and so on, i.e. the number of calculations your computer must process. So the more you apply, the more it has to work through. Your Question (and answers) are posted endlessly allover forums but In my opinion, I humbly suggest you run a series of tests, gradually increasing your render options and settings on your machine to figure out it's 'slow' point. From there, you will be able to figure out how much time you are prepared to invest per rendering. Hope this helps.

I've got a model of a landscape-like form that I want to produce on a CNC router. I struggled with finding a way to extend the edges, slice them off at the bottom and close the bottom. I ended up using Meshmixer for that, because with Modo I kept ending up with weird puckers at the bottom edge. Now I'd like to slice the model into one-inch thick sections so I can make the model on the router (I have to do it that way due to the length of router bits) and nobody on the Modo forum has been able to give me a way to do that. Anyone here know? I thought I'd be able to do it with Meshmixer, but I can't figure out how to move the "Plane Cut" to precise increments and for some reason, I have not been able to sign up for the forum. And there is no documentation for the new version of Meshmixer (seriously!).

Got the model sliced with the assistance of Mads and wanted to follow up in case this discussion helps someone else down the road. It was not necessary to freeze the geometry. The problem was intersecting edges that created hidden polygons inside the model. To get rid of those, first find them by setting the viewport to Advanced Open GL with Ray GL: Full. The problem areas will appear black. Then select the problem areas and use the Utilities: Relax mesh tool in the Sculpt palette with iterations set between 1 and 5 to produce a very subtle change. Go over the problem areas until the black color goes away. After that, Mads was able to slice it in Rhino on a PC using Mesh Boolean: Boolean Split. For some reason, I wasn't able to get that to work with the Mac version, but I accomplished the same thing using Mesh Boolean: Boolean Difference. You just have to make sure the surface normals of the cutting plane are pointing in the right direction if you use Boolean Difference.

Here is my Topo tab view of my shoe last. hm... is there a Modo complete reset? maybe I clicked something I shouldn't.

Ahhh, yes. Glad you figured that out. Static meshes are evil.

I've been backed up a bit filling some orders but finally cleared my plate to work on my neck project some more.  I've managed to make 3 different neck to headstock transitions that are configurable and got my design table started (finally)

There is some sensitivity to parameters in that you can push them where it will break the model but I might be able to fix some of that in excel. 

One interesting thing was that when working on the "Smiley" volute, I spent about an hour or so trying to slice it up so that I was only using 4 sided boundary surfaces but still couldn't get a result I liked.  In desperation, I used the Filled Surface feature on a 5 sided surface and it actually gave me the best results. 

If all goes well, I'll be cutting a prototype from cheap wood before the end of the week.

p.s., the headstock is just a paddle to allow customers enough material to modify it as they like.

Not a bit of it! I use it all the time. In many cases it works brilliantly.

Hi Cadjunkie Crew, now that I am out of school and looking for my own software what permanent license software that is compatible with Solidworks do you recommend?

Oh I see, then your options are pretty limited. If there were something sufficiently similar to SW that you could do all the same things, but at a lower price, why would anyone buy SolidWorks? Is there an alternative you're looking at?

Hey Adam, 
                     Care to do a short video on a simple footbed in SW?  Im thinking the side rail sweeps and the top portion (loft?) where the foot rests. picture (from CJ2009) below:

Hi There,

Used your tutorials to work on a parametric neck for CNC production.  Ultimately, this will be a design table driven part but so far so good!  The Diamond Volute was tricky to get right but I finally got it I think.  Also, in your tutorial, if I'm remembering correctly, you didn't include the thickness of the nut when determining your neck length.  Not that big a deal though

Haven't seen anything in the MODOsphere lately. Any chance of getting something on Mesh Fusion, for instance? Or Dynamics? I'd love to see a swinging wrecking ball knock over a wall of bricks for instance. I can make that work beautifully in Cinema 4D, but couldn't keep the chain from jumping around crazily in MODO.

Well, real work comes first, I'm sure your wife would agree.... I'll be looking for whatever you do post for us. It's always good to see your methods.

Hey CJ community. Another Rhino/Tsplines Question.  I am trying to insure that the bottom of this shoe form is flat. Is there a way to make sure it is? can I snap to a flat plane? thanks!

Hey CJ crew,
               I am finally getting my hands dirty with Modo.  I am trying to wrap my head around modeling with sub-d verses solids and how to get accurate dimensions off of your models in Modo.  Any advice for a SW user?

No, there's very little in the way of documentation. Of course there's the modo SDK wiki (http://sdk.luxology.com/), but other than that it's just asking questions on the SDK forum (http://community.thefoundry.co.uk/discussion/forum.aspx?f=37). The main thing is to get familiar with the "History" and "Commands" tabs in the history palette (F5), and to play around with the System > Record Macro. From there you'll graduate to Python "fire and forget" Scripting, and, eventually, the full Python API. 

It's not easy, though, and the lack of documentation is frustrating to say the least.
