Here's what I have so far . . . can't seem to get the results I want. How do I connect them? Tried doing like the guy in the video but my lines went all haywire.

Hi Neil, can you show an example of one of your haywire curves? That would probably help to see what's going wrong.

These are pretty crooked and lumpy - and not sure how to delete unwanted parts . . . just need a lot more practice making curved lines.

Hi Neil,

I don't know much about CNC, would you approach this with the profile of the cutting tools used with the machine?
Maybe a kind of tool path that would be subtracted?

This one is pretty good - sometimes the planar, loft and network work easily - sometimes they don't - need to learn what has to be to make using them successful more consistently. There must be rules for those commands. The headstock to the neck is the most challenging apparently - the heel wasn't too hard . . . progress anyway. Thanks to Michael for all the helpful tips, techniques and guidance with the program.
Attached is the latest version.

Here's a little progress - still not happy with the transitions - but so far this is as good as it gets. Is there some kind of mesh tool that can be used to do this better like the guy in the Rhino neck video? Put a fretboard on this model (will make the fretboard separate from the neck) - just to get the look of the neck profile. How do I put a top on the headstock? This was made using the network and lofting commands - so it wasn't solid - when I cut the top off - it was hollow! lol - how do I fix this? Thanks!

Hi Neil, that's coming along pretty well!

re:

What's the time index of this spot in the video?

If the various Network and Loft surfaces are touching each other, you can make them into a solid by using the Edit > Join command.

Otherwise to work with surfaces instead of solids you could do an extrusion of your cutting side profile and trim that, similar to what's shown here:

Do you maybe have a version saved just before you did the cut? If so that would be good to see.

Hi Neil,
the following method may help.
I have named the curves to show how it was done.
Hope it helps.
Barry.

Wow - that is a very cool method - thank you very much for sharing!

---

Thanks for the help - which has helped me realize I need to start over from the beginning - onward!

---

I have not been able to duplicate this correctly.

---

Hi Neil, please post what you have tried so far, that could help to give some ideas on what to do about it.

Just reading that you haven't been able to duplicate it doesn't give enough information about what you are seeing to be able to help any.

Hi Neil,
if you select the objects as named in the browser.
1) Loft Elipse's.
2) Extrude ends tick extruded both sides.
3) Boolean join neck to bottom.
4) Fillet the join with 0.25 radii.
5) Separate Solid Head so you can trim.
6) Select the end cap of neck and delete it to allow blend.
7) Blend between neck and head (add sync points if required).
8) Select all and join surfaces to create solid.
9) Boolean Diff Boolean lines and delete unwanted pieces.

Cheers
Barry

Thanks Barry - with the further explanation it went great. That's so clever! Can't thank you enough for sharing your expertise.

Thank you Michael, very useful tip - this will come in handy.
