Need Help!- Rhino - Neck/Head Joint

[nenoneno]

Hi!

I have the following problem in Rhino: I want to make a smooth surface which connects the Head of a guitar and the Neck. The following picture should give you an idea of what i mean. The joint has to be clean and smooth, because i need the modell later on for rendering purposes.



And here is the joint on a real guitar:

That looks alot like the Ken Lawrence headstock ? not sure whether he would approve of someone copying his trademark headstock .. anyway it looks like a good model for sure.

I can put a surface in that area,
What radius to the flat? or
do you want a smooth tangent curve?

[nenoneno]

Thanks for the replies!

1.) Yes, it is a Ken Lawrence Explorer and it's pretty accurate I think. However I just modell it for rendering purposes, not for building and sharing it I need the neck joint actually for a Les Paul-like model

2.) To bostosh: You mentioned it: a smooth tanget curve

neno,
I can make it look just like the original, I need to think a little, about exactly how.

Nice to hear

Thanks!

hi, i'm a solidworks user
send me an iges and i finish it (should take less than 5 minutes)

Thanks fabconv for your offer!

You see, I want to know how I can modell that in Rhino, because there must be a way and I will need to know how to solve this "problem" for future projects. I also don't want to annoy you by sending you 10 modells and saying: "pls make this again" . I'm sure you are kind and would do that but you know what I mean

If I don't find a solution I will gladly accept your offer!

Thanks!

Try to connect the surfaces of the headstock, so that they form a single edge. Or duplicate edges and make a single curve of it.
Make lines closest to the fretboard and use as cross sections, else you will not get a straight connection at the sides.
Then you either use the neck and headstock curve as rails, and do a sweep with your three cross sections, alternatively try my favourite; the curve network command.

Well, none of my methods yielded very good surfaces, but I found another way that can be adapted to the situation.



First extend your original lines until they meet.
Then do a surface from curve network. Specify tangency to the neck surface edge.
Then do a split in the desired plane, and cap the opening. Voila!

You may have to adjust the height of the curves to get a nice radius at the split line.

Hi!

Thank you very much LN-JET for your help!!!! I think that's it. I currently don't have time to try it but I will post my result as soon as I can!

Thanks again

Hi!

I've tried the solution and it's good but not 100% smooth.

Here is what I get:
