3D Modeling and Drawing
What is it?
A 3D Model is a mathematical representation of any three-dimensional object (real or imagined) in a 3D software environment. Unlike a 2D image, 3D models can be viewed in specialized software from any angle, and can be scaled, rotated, or freely modified.
The process of creating and shaping a 3D model is known as 3d modeling, or the process of creating a 3D representation of any surface or object by manipulating polygons, edges, and vertices in simulated 3D space. 3D modeling can be achieved manually with specialized 3D production software that lets an artist create and deform polygonal surfaces, or by scanning real-world objects into a set of data points that can be used to represent the object digitally.
Free 3D Design Software
Tinkercad
A fantastic beginner program, that leads you to learn complex things through simple quests. Runs right in your browser, and the skills you learn are easily transferable to more advanced programs.
Online Service

Windows, Mac, Linux
FreeCAD
An open source parametric 3D modeler, great for both the home user, hobbyist and experienced designer. Parametric modeling allows for easy editing of your design.
Windows, Mac, Linux
Open SCAD
OpenSCAD is not an interactive 3D design tool. It is something like a programmatic 3D-compiler that reads a script file containing 3D geometry definitions, and in turn generates a solid 3D model as output.
