Technical Requirements 技术要求

You will need a free autodesk account to use throughout this course. You will be asked to sign up the first time to access any of the software. This will be used to access the software online(Tinkercad) and to download software as well(Fusion 360 and Sketchbook). We will also be using sketchfab to publish designs later in the course, which will require a separate free signup.
您需要注册一个免费的 Autodesk 账户以在本课程中使用。您首次访问任何软件时将被要求注册。这将用于在线访问软件（Tinkercad）以及下载软件（Fusion 360 和 Sketchbook）。我们还将使用 Sketchfab 在课程后期发布设计，这需要单独的免费注册。

Most of the software used in the course would require a computer where you can download the software. A Tablet or a mobile device will not be sufficient. Detailed system requirements for each software is available on the linked pages below.
课程中使用的软件大多需要一台可以下载软件的电脑。平板或移动设备不足以满足要求。每个软件的详细系统要求可在以下链接页面找到。

Course Outline 课程大纲

This course consists of 5 weeks of materials.
这门课程包含 5 周的材料。

Module 1: Design Sketching for 3D Printing (10% of the grade) 模块 1：3D 打印设计草图（占总成绩的 10%）

Design starts with capturing our ideas and a great starting point is to draw. In this module, you will learn how to draw and communicate your ideas. This will set you up with the foundation to express yourself in three dimensions in the subsequent modules.
设计始于捕捉我们的想法，一个很好的起点是绘画。在本模块中，你将学习如何绘画并传达你的想法。这将为你打下在后续模块中以三维方式表达自己的基础。

Key Concepts:  关键概念：

• Vanishing points  消失点
• 3-point perspective  三点透视
• Layer  层级

Module 2: TinkerCad (10% of the grade) 模块 2：TinkerCad（成绩占比 10%）

In this module, we move from expressing our ideas in two dimensions (sketching) to expressing them in three dimensions. You will learn how to use Tinkercad, which is a great software for beginners, before we learn more advanced modeling software (Fusion 360) in week 3.
在这个模块中，我们从用二维（草图）表达我们的想法转变为用三维表达。在第三周学习更高级的建模软件（Fusion 360）之前，您将学习如何使用 Tinkercad，这是一款非常适合初学者的优秀软件。
