What is a .L3B file?
An .L3B file is a special kind of computer file that is used to keep information about 3D models of LEGO pieces. Think of it like a digital blueprint that tells a computer program how to show a LEGO model in three dimensions, including where each LEGO piece goes in the model. This file is made by a computer program called SR 3D Builder, which lets people create their own LEGO designs on their computer, like making a digital version of a LEGO truck, a dune buggy, or even a front end loader.
To look at or work with these .L3B files, you can use programs like LDview or SR 3D Builder itself. These programs let you open the .L3B files so you can see the LEGO model in 3D on your computer screen. You can turn it around, look at it from different angles, and even make changes to the design if you want.
However, if you ever want to take your digital LEGO model and make a real-life version using a 3D printer, you can't use the .L3B file directly. Instead, you need to first open your .L3B file in a program like LDview, and then change it into a different type of file called .STL. The .STL file is a common type of file that 3D printers can understand and use to print your LEGO model in real life.
