“I live my life a 1/8 mm at a time”

Guitar neck topology is worth going microscopic. 🔬🦠 After building my starting surface from a wireframe network in the sketch environment; a system of 4-degree control point spline rails, tangent to projected isoparametric curves along the shaft — I can convert the NURBS surface to a T-Spline and start cleaning up the artifacts left behind by the original loft. In this demo I’m turning on Box Display, which feels strange at first because…

Fast & Curious 3: Parametric Drift

https://www.instagram.com/reel/DWAuW40jAR_/?igsh=MW1jNDdoYzllMGFmMA== I’ve spent a few overly caffeinated days bouncing between modelling environments, different combinations of operations, tools.. subtle differences in how the coffee is brewed. In short… • Building Iso Curves in Sketch. Defining the surface structure and flow • NURBS Surfacing from curves, smooth intentional surface topology. • BRep Face to T-Spline in Form Environment.

Brett -- If you are doing free-form modelling, have you tried using Shapr3D software? I just started playing around with it and it seems to be reasonably intuitive and easy with which to get started.…

2 Surface 2 Transition

Back at tinkering with the new Isoparametric Curve tool in Fusion. Scroll down to PICTURES LETS GO! If you want to skip this little walk through Autodesk Fusion memory lane, clearing up some of the UI conFusion. Why something so seemingly basic, is just being added today. 2009- Autodesk Inventor, hybrid modelling experiment, parametric and direct CAD in one hybrid system. 2011- Autodesk acquires T Splines Inc. an organic modeller still in…

Fusion Surface Transition Update

I had a feeling I should have updated Fusion before 3D Club... Todays New update introduced Project Isoparametric Curves "Isoparametric curves in the Sketch environment, adding new ways to extract surface U and V curves for more controlled lofts, rails, and surface transitions" ...The meridians on the shaft surface seen in the attached photo. I still haven't fully grasped how to align these between faces, attached is a quick…

Spline Routing Jig

Hey all! First time posting around here, so forgive me if this has been talked through before, but I'm on the hunt for some jig plans for routing splines on headstock repairs. Thanks so much for any help or direction on this!
