Rhino Basics, Week 04

Posted by adam on Feb 2, 2010 in Tutorials | 4 comments

This is the fourth week in a series on the fundamentals of Rhino, as taught at Otis College of Art & Design in the spring semester of 2010. To follow the tutorial from the beginning, start here. There is a parallel series covering the basics of SolidWorks here. Enjoy!

This week we’ll be looking at Non-Uniform Rational B-Splines, or ‘NURBS’. Rhino is a NURBS modeler, so it’s critical that we take some time to understand at least the basics.

The first video covers:

- Reviewing basic surface editing tools:
- trim
- fillet
- blend
- offset
- project

More videos after the jump:

- defining NURBS
- drawing CV curves
- degree 2, 3, 5, and 7
- curvature graphs

- NURBS in 3D
- U and V directions
- surface rebuild

- basic surfacing tools:
- loft
- sweep one rail
- sweep two rails
- revolve

- SetPt

- basic coffee carafe
- intro ‘primary’ vs. ‘secondary’ surfaces

- intro revolve
- intro patch

- homework:
- twisting a trimmed surface
- rebuilding after using ‘twist’ and ‘bend’ functions
