                  TINKERCAD – AN INTRODUCTION                                                            CHAPTER



















                     Topics Covered


                     The student will be able to:
                        Understand 2D and 3D objects.                    Navigate and use Tinkercad for 3D modeling.
                        Modify and align shapes in a 3D workspace.




                  Have you ever wondered how video games, animated movies, and 3D-printed objects are made?
                  They all start with 3D modelling! In this chapter, you will learn the basics of creating 3D shapes
                  using Tinkercad, a simple and fun online tool for designing 3D models.




                            UNDERSTANDING 2D AND 3D OBJECTS

                  In  the world of shapes and geometry,  we often come  across two types  of figures:  2D or
                  Two-Dimensional shapes  and 3D or Three-Dimensional objects.  Understanding  the difference

                  between them is important, especially when learning about modelling and design

                  WHAT ARE 2D SHAPES?
                  A  Two-dimensional  shape  is  flat  and  has  only  two  dimensions:

                  length and width. These shapes do not have depth and cannot be
                  picked up or held. They can only be drawn on paper or seen on a
                  screen.

                  Examples of 2D shapes: Circle, Rectangle, Star, Cloud, and Triangle.

                  Where do we see 2D shapes?

                      Drawings and paintings
                      Flags and signs
                      Designs on clothes
