| Command | Purpose | |---------|---------| | ExtrudeCrv | Push curve straight (cap ends) | | Loft | Skin across multiple section curves | | Sweep1 | 1 rail + profile(s) | | Sweep2 | 2 rails + profile(s) | | Revolve | Spin profile around axis | | NetworkSrf | Grid of crossing curves (most powerful) | | Patch | Fit surface through boundary curves | | PlanarSrf | Flat surface from closed curve |
Before we touch a curve, you must understand why Rhino is different. Rhino 3d - Any Version - Beginner Level To Advanced Level
Once you master NURBS logic and the ~50 core commands above, you can model anything from jewelry to aircraft. Rhino’s depth is in its precision and lack of arbitrary limits – the only ceiling is your geometry imagination. | Command | Purpose | |---------|---------| | ExtrudeCrv
Once you can make a box, you want to make a sports car. This is where you transition from "Sketching" to "Modeling." Once you master NURBS logic and the ~50
You cannot build if you cannot see. Your first hour in Rhino should be dedicated to mouse navigation:
| Category | Command | What it does |
| :--- | :--- | :--- |
| Transformation | Orient, Flow, OrientOnSrf | Maps geometry along curves or onto surfaces. |
| Surface Creation | Sweep1, Sweep2, NetworkSrf, Loft | Creates surfaces from guide curves. |
| Analysis | Zebra, CurvatureAnalysis, EdgeContinuity | Visually checks if surfaces are smooth (G1, G2). |
| Control Point Editing | TurnOn (control points), Weight (change point weight) | The secret to organic shapes. |
Advanced users run ShowEdges or Check (Check command).
