3D modeling software is used to create a 3D digital representation of any object or surface. The software performs this task by allowing users to manipulate points in virtual space to form a mesh (the set of points that make up an object). 3D modeling is an integral part of many creative professions, including special effects, animation, game design, and architectural planning. There are a variety of 3D modeling software products on the market, from mid-priced products with limited functionality to high-end products that provide the tools you need to create games, animations, and more.
In 3D modeling, it's important to note that this is a very technical skill and difficult for the average person to master. This can be learned over time, but it is often helpful for the user to have a basic knowledge of 2D modeling and a deep knowledge of spatial awareness in modeling. There are also many free and cheap 3D models.
