What is a STP file?
STP is an alternate file extension for STEP files (Standard for the Exchange of Product Model Data), an ISO standard used to exchange 3D CAD data between different software platforms.
STP files contain highly detailed 3D models, including geometries and product structures, and are widely used in engineering, manufacturing, and architecture for cross-platform collaboration.
How to open STP files
STP files can be opened in nearly all modern CAD software such as SolidWorks, FreeCAD, Fusion 360, CATIA, and more. They allow seamless interoperability for mechanical designs.
You can use AnyConv to convert STP files to formats like STL, IGES, or STEP to meet the needs of 3D printing or collaborative projects.

What is a 3DS file?
3DS is a legacy 3D file format developed by Autodesk for its old 3D Studio DOS-based program. It stores geometry, textures, lighting, and animation data, and was one of the earliest widely supported formats in 3D graphics.
Although now outdated, 3DS files are still readable in many modern 3D tools and game engines. They are often converted to more modern formats like FBX or OBJ for continued use.
How to open 3DS files
3DS files are supported by many 3D modeling programs, including Autodesk 3ds Max, Blender, and SketchUp. While it's an older format, many modern tools can still read or convert it.
Use AnyConv to convert 3DS files to OBJ, FBX, or STL for improved compatibility with newer software.
