WHAT ARE 3D OBJECTS?
                 A Three-dimensional object has three dimensions: length, width, and height. These objects take

                 up space and can be held in real life.
                 Examples of 3D objects: Cube, Sphere, Cylinder, Cone, and Pyramid.


                 Where do we see 3D objects?
                     Buildings and houses

                     Toys and sculptures
                     Balls, boxes, and bottles

                 Representation        circles, and triangles.                and pyramids.

                 Visual View           Only front view is visible.            Multiple angles or views can be seen.




                           INTRODUCTION TO TINKERCAD


                 Tinkercad is a free, web-based 3D design tool used for creating, modifying,
                 and exporting 3D models. It runs in a web browser and does not require any
                 software installation. It was founded by former Google engineer Kai Backman
                 and his co-founder, Mikko Mononen. In May 2013, Tinkercad was acquired by
                 Autodesk.


                 FEATURES OF TINKERCAD:

                     User-Friendly Interface — Designed for beginners, Tinkercad provides an intuitive drag-and-
                     drop interface for creating 3D models.
                     Browser-Based — No need to  download or install any software; it  runs  entirely  in a web

                     browser.
                     Shape-Based Modelling — Users can create complex objects by combining simple geometric
                     shapes.

                     3D Printing Compatibility — Models can be exported in STL or OBJ formats for 3D printing.


                 APPLICATIONS OF TINKERCAD:
                     Education — Used  in schools  to  teach  STEM (Science,  Technology,  Engineering,  and

                     Mathematics) concepts.
