The “.STL” file extension is associated with Stereolithography files, a common file format used in 3D printing and computer-aided design (CAD). STL files contain a representation of 3D models using a series of connected triangles, defining the geometry of the object.
How to open an STL file:
To open and view an STL file, you would typically use 3D modeling software, CAD software, or specialized STL viewers. Here are the steps:
1. 3D Modeling Software:
- Professional 3D modeling software like Autodesk AutoCAD, Blender, or Rhino can import and work with STL files.
2. CAD Software:
- Computer-aided design (CAD) software, including programs like SolidWorks, Fusion 360, or CATIA, commonly support STL files.
3. STL Viewers:
- There are standalone STL viewers available that allow you to open and visualize STL files without the need for full-fledged 3D modeling software. Examples include MeshLab and 3D Builder.
Programs that may open STL files:
1. Autodesk AutoCAD:
- AutoCAD is a professional 3D modeling and CAD software that supports STL files.
2. Blender:
- Blender is a powerful open-source 3D modeling and animation software that can import and work with STL files.
3. MeshLab:
- MeshLab is a free and open-source mesh processing software that allows you to view and edit STL files.
4. Windows 3D Builder:
- 3D Builder is a built-in application in Windows 10 that can open and manipulate STL files.
