3D STUDIO
Four models you can actually handle
Place every fret and read the intonation error, work a neck through relief and action, change a bracing pattern and watch the stiffness move, and walk a whole setup from relief to intonation. All four are built from the same numbers the reference pages use.
Fret Placement Simulator
Build a neck in 3D, set the scale length and the temperament, and read the exact position of every fret, the note it produces, and how far off it is in cents. The model recomputes from the same maths the fret spacing calculator uses.
Neck Relief & Action Simulator
A neck you can bend with a truss rod, strung with strings you can change, over a bridge and nut you can raise and lower. The action at every fret is computed live and shown in millimetres, with a warning when the geometry is wrong.
Bracing Pattern Simulator
A guitar top with its braces, in 3D, with the bracing pattern and the brace dimensions under your control. The model reports the resulting stiffness and the resonant character, and flags a structure that is too thin to hold.
Setup Wizard
A complete guitar you can rotate freely, with a step-by-step setup that walks through relief, action, nut height, intonation and a final check. Each step shows the measurement, the target and the adjustment, and the finish is a setup report.
How the 3D tools load
The 3D libraries are only fetched when you open one of these pages, and on a small screen each tool opens as its static reference version until you ask for the interactive one. If your browser or device has no WebGL, every tool falls back to a static model that carries the same figures and the same steps.
Best on a desktop
The models are built for a mouse and a larger viewport. On a phone they open as the static reference and offer a button to load the 3D version anyway.
No external requests
The 3D library, the textures and every illustration are served from this site. Nothing is fetched from a CDN and no model file is downloaded.
Reduced motion respected
If your system asks for reduced motion, automatic rotation, the vibration animation, camera moves and the tuning chime are all switched off.
