Examples of 3D objects: Cube, Sphere, Cylinder, Cone, and Pyramid.
Where do we see 3D objects?
Buildings and houses
Toys and sculptures

INTRODUCTION TO TINKERCAD
Tinkercad is a free, web-based 3D design tool used for creating, modifying,

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.
