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 STL file?

STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.

STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.

How to open STL files

STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.

Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.
