Beginner question, arch top guitar model

I do alot of woodworking with my CNC at home and have used different software to create 3D models of a Les Paul type guitar arched top.

 

I am having a hell of a time making a complex curve outlines shape that also has complex curved top surface.  

 

I have no problem sketching the shape of the body and extruding a shape to the complex outline.  The problem is getting the arched top portion.  Any tutorials that may help me figure this out?

 

Thanks

Coolest...thing...ever.  I'd say the long nights are going to pay off.  And now you have some awesome modeling skills!

I was just curious, do plan on machining the body to be hollow (as you can tell I'm not the most knowledgeable about guitars, but I'd assume for electric the body can be solid).  Also, how did you do that guitar with the skull 3d relief?!

There are hollow body and partial hollow body guitars.  They dont have to be solid.  I will proabably make it a partial hollow to reduce weight.

 

The skull was done by using a grayscale image to make relief bitmap, making the darkest spots the deepest, in this case about 0.125 ".  It was done with some other wood working friendly gcode software.

Gotcha.  Pretty unique.  The next "Gibson" 😉

This is a real great study in how to build a complex shape. I wonder if you would be willing to explain the changes you made to arrive at the final model.I've looked at the LP file and the original looks very good.

Thanks for all the info and work that went into your Les Paul.

And a short follow up on how to trim the surface back....

Thank you very much for taking the time to solve this, I guess from this point all it takes is to slice the neck and pickup planes, does the order of plane trimming affect the end result in any way?

I found it to work best to trim the neck and pickup planes last, but patch the section after each cut/trim.

Just had a chance to view this post and I'm blown away. I've built my guitars by hand and done the whole contour top bit by hand but started looking into how to do this using the technology that's available. That's when I found about Fusion 360 and now I'm going down a whole new road. Doing contour tops by hand has become a bit harder as I've gotten older and if I can do it using this amazing program it sure will make life easier. I'm just a hobbyist and build guitars for myself and to keep the brain working in my retirement. This is absolutely great and my hats off to the folks on this site. This is a great community of people and I've already received more help than I could have imagined. 

 

Kudos to everyone.

 

Cheers!

So after alot of fussing with how to machine the model, I finally built the jigs and pulled the trigger on the CNC machine and milled the neck which had been holding me up.  Unfortunately the CAM in Fusion 360 baffles me on how to properly set it all up.  I exported the models as STL files and used a cam program that I am more familiar with.  Anyway here are some photos of the parts cut using the Fusion models I made.  The neck could not be completely cut with the CNC (will finish by hand) as my machine doesn't have the travel required to do it all unless I break up the milling in multiple setups and using shorter tools in the various setups.
