Class 3E
Apr 13, 2016

Today’s session (split in two classes, actually) mark the first deadline – students will submit the rough prototypes of their ideas. Based on that prototype, we will do two types of tests.

Homework: Form Analysis

Analyse the form of your object, and sketch the process of how you plan to model it in Rhino.

What you need at this point is to sketch how the object’s form can be achieved by combination of more basic forms and/or the Rhino surface modeling techniques (see tutorials below).

In order to do that, you need to figure out what are the most important lines that define the shape of the model. These are typically the edges of your object: sketch them on paper, and then see what Rhino operations would be most appropriate to create surfaces based on these lines. Do not limit yourself to your current knowledge of Rhino modeling (which is probably limited to polygonal structures) – this is the great time to learn how to create anything you imagine, and it’s not that difficult.

Form analysis doesn’t have to be very elaborate; it will mostly serve you as a plan on what you plan to do in Rhino to create the object.
One example, for a very simple object, though:


For the next class (session 4A, Monday April 25th), all students should have:


Please take a look at these Rhino tutorials that will help you in your modelling effort. Actually, these are not tutorials per-se (except for the first one) but a quick reference on most important techniques. The way to use these tutorials is more like Dictionary: when you need to make something, check in my examples for something very similar and see how I made it.

Rhino: Modeling From Photos
In this tutorial you will learn how to create 3D models in Rhino based on reference photos of objects or your paper sketches.
Rhino: Working With Lines
This post is a reference of most often used Rhino commands for manipulating curves.
Rhino: Creating Surfaces
This tutorial is an overview of most used methods to create 3D surfaces from 2D and 3D lines.
Rhino: Edit And Combine Surfaces
This tutorials gives overview of the most useful methods to manipulate and combine surface.
