Crustacean Introduction


Introduction: Crustacean Introduction

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

Project Overview:

Learn how to use advanced duplicate techniques to grow a unique crustacean shell.

Step 1: Introduction

Here you will see a wheel and our crustacean friend Phil. Crustaceans have a hard shell on the outside of their body. When they grow, they shed their shell for a bigger one. Phil needs a new home, lets design one for him!
To help us do this, let's learn about an advanced feature of the Duplicate Tool. The duplicate tool not only makes a copy of an object, but can remember how much you move, rotate, and/or scale the object. As long as the copy remains selected, any changes will automatically be applied to the next duplicate.

See an animation of this process.

Step 2: The Wheel Guide

The wheel on the workplane is a guide. The first few objects should fit within the ring of the wheel. The lines inside the wheel can help with symmetry and balance. Lets get started on a sample shell.
