Do you perform the loft with the two curves on the same plane and then start raising control points, or do you raise the centerline to the height of the top before lofting? I did my loft with the centerline raised before the loft, and I get a ridge that is proving difficult to smooth out.There's a number of ways to model a top carve but here's a method I use sometime. It's a basic freeform modeling technique that's really fun.
This example isn't vintage accurate or anything, it's just a method of modeling.
First, cut the perimeter of the upper horn and extend it parallel and draw a centerline roughly as this pic.
Loft the two curves.
For this method I have all the curves at the same plane when I loft them, then I raise the center control points.Do you perform the loft with the two curves on the same plane and then start raising control points, or do you raise the centerline to the height of the top before lofting?

I am also wondering, how do you CNC route an angled pickup cavity, since most CNC routers (at least the ones within reach of a typical guitar builder) cannot undercut. Do most of you revert to templates and handheld routers, or do you construct a jig to hold the body at an angle? I'm leaning toward using an ordinary template, since I wouldn't have to have different routines for single-pickup and two-pickup guitars (I always route a single-pickup guitar internally for two pickups, just to make it easy if I ever want to add the second pickup later).
One more question: when modeling the fretboard, will it be sufficient to draw a line where the fret goes or will I need to actually model a .023 cutout for most CAM programs to recognize that there will need to be a cut?
I didn't just extend the outline, I drew a new line on top of the outline, from the center point of the bottom of the guitar to the extended portion.Hello i am also studying industrial designer. i build a ukulele last year and now i want to try to build a les paul. I m also new to rhino.. but i am really good in solidworks.i put myself the challange to build the LP in rhino first and use the data for cnc machining.
i already started the body, made the cutouts for the cavities. But now i stuck at the carved top.. i read all posts of the thread but the methods do not work. If it follow the instructions by GooCart and loft between the extended outline and the centered line rhino creats two polysurfaces. Only if i tick the rebuild option in the loft menu it's one surface. But then it doesn't match my outline. So i don't know what i am doing wrong
maybe somebody could help me?
