INTRODUCTION TO TINKERCAD

Tinkercad is an easy-to-use and simple 3D design and modelling software.
It runs on a web browser. It was created by former Google engineer
Kai Backman and his friend Mikko Mononen in 2011. It allows building
3D models and makes designing easy and simple.
In school and daily life, you often need to make models, solve problems or share ideas.
Drawing by hand can take a lot of time. Software like AutoCAD, Blender, SketchUp, SolidWorks FEATURES OF TINKERCAD
and others help with designing. In this chapter, you will learn about Tinkercad, a fun and easy
computer-aided design tool that lets you create 3D models and show how things work on your Some of the key features of Tinkercad are:

computer. User-friendly Interface: Easy for beginners with drag-and-drop 3D model creation.
3D modelling and printing: Create 3D models and export them for printing.

UNDERSTANDING 2D AND 3D SHAPES Shape combination: Combine simple shapes to form complex geometries.
Collaboration: Share projects and collaborate with others for joint design work.
In daily life, you must have seen many two-dimensional and three-dimensional shapes.
Understanding the basic difference between them is important, especially when you are going APPLICATIONS OF TINKERCAD
to learn about three-dimensional modelling and design. Some of the key applications of Tinkercad are:

WHAT ARE TWO-DIMENSIONAL SHAPES? 3D printing: Design models for 3D printing with ease. Tinkercad was acquired by
Autodesk in May 2013.
Two-dimensional shapes have length and breadth, but no depth or height. They can be drawn on Educational tool: Used in schools for teaching 3D design,
a flat surface and have an area and perimeter. These shapes are visible only on a screen or paper. engineering and electronics.
Some examples of two-dimensional shapes are: Product prototyping: Helps engineers create quick prototypes and visualise designs.

Engineering education: Helps students learn design, measurement and mechanics.

WHAT ARE THREE-DIMENSIONAL SHAPES? 2. Tinkercad is an easy-to-use and simple 3D design and modelling software.

A three-dimensional shape has three dimensions: length, width and height. These shapes take up
space and can be held in real life. These shapes can be viewed from different angles.
