3D design is extremely important for this reason: engineers, architects, and the like use 3D CAD programs to design things before building them all the time. 3D modeling allows engineers to flush out their ideas before they become reality, so most objects that you see around you were first designed in 3D design software by engineers before they were made. There are hundreds of different 3D design programs out there, each for a specific application. In this Instructable you'll learn some of the basics of 3D modeling and why it is important.įrom movies to manufacturing, 3D modeling is incredibly useful. If you've heard of 3D printing, 3D modeling is what is used to design objects before they are 3D printed. Modeling programs allow you to create and visualize final products, modify and optimize the designs, and document designs, measurements, and materials easily. to anyone viewing the design, and can be used to make control paths for Computer Numerical Controlled (CNC) machines.ģD Modeling in general makes the product design process more efficient.

The computer model is used to communicate dimensions, material types, etc. It is used in a variety of applications, mostly when it comes to designing parts on the computer to assist in the making or visualization of those parts. 3D modeling is a subset of Computer Aided Design (CAD), in which you use a computer to assist in the design process for any type of design work. 3D Modeling is used in a variety of applications to make representations of physical objects on the computer.
