I've been trying, for the past few days, to model an acoustic guitar entirely to practice on non-flat surfaces!
Overall, I'm not doing too badly, but I'm sticking to the modeling of the neck. And especially the " heel " which is the junction between the neck and the body.
It uses two 3D sketches that group the scattered entities of the sketches in your initial model into splines, simplifying future selections. The first takes up the longitudinal lines of the handle, the second the transverse sections.
The back of the handle is generated by volume smoothing.
Hello Benjamin I can't read the file but I see in the image mistakes not to make. When using guide curves, you do not have to force perpendicularity or alignment on vectors to succeed in the scan. Then pay attention to the guide curves that they intersect all the sections. You have to include the two guides from above
