What is STL file in CAD?

STL is a file format native to the stereolithography CAD software created by 3D Systems. … An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system.

How does an STL file work?

An STL (Standard Tessellation Language or STereoLithography) file is a format that describes surface geometry of a 3D object without any colour, texture or other attributes. This format uses a series of linked triangles to recreate or reproduce surface geometry of the 3D model.

Can AutoCAD open STL files?

While some CAD programs are able to import STL files, AutoCAD users will know that it isn’t possible with this software. DWG is the native file format of AutoCAD that can store both 2D and 3D data. It’s highly compatible with other CAD software, making it one of the most commonly used formats around.

What is a drawback of STL files STL files?

A major disadvantage of an STL file is that it can be very hard to edit outside of simple scaling of the model. Since an STL model only contains an approximation of the original 3D model and not the model itself, it’s often easier to start a model from scratch than to modify an existing STL file.
