                            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:

                         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.
