3D modeling basics

3D modeling is the usage of computer software to represent an object in three dimensions. Different softwares can be used to create the objects but they all have the same fundamental idea. 3d models are made with the interaction of a simple handful of peices. In some sftware models are made with sketches made from mostly straignt lines and rectangles that interact with eachother through extrusions. Other software uses basic shapes that can be modified to create more complex images.
