.STP File Extension

A .STP file is a STEP 3D CAD File, created by International Organization for Standardization.

Open with Dassault Systemes CATIA. Available for Linux, Windows, and Mac.

What is a .STP file?

An STP file, which stands for STEP 3D CAD File, is a type of file used to store three-dimensional designs and data in a format that can be shared across different computer-aided design (CAD) programs. This file format is particularly useful in the fields of engineering and manufacturing where collaboration and file sharing are crucial.

The content of an STP file is saved in the Standard for the Exchange of Product Data (STEP) format. This format is standardized under the ISO 10303-2xx Application Protocols, ensuring it meets international norms for industrial data exchange. The data in an STP file is typically stored in a text-based ASCII format, which can be read and written by various software programs.

STP files are widely supported by a range of mechanical design and CAD software. Some of the key programs capable of opening STP files include: - Autodesk Fusion 360: A popular CAD/CAM tool that supports 3D modeling, simulation, and design. - IMSI TurboCAD: Offers professional-grade CAD tools that can work with STP files. - Dassault Systemes SolidWorks and CATIA: Both are advanced CAD software systems used by professionals for complex engineering projects. - Siemens Solid Edge: Known for its solid modeling and assembly capabilities. - CADSoftTools CST CAD Navigator and ABViewer: These tools provide capabilities for viewing, converting, and editing CAD files. - Kubotek KeyCreator: A precision CAD software used for creating and editing designs. - Okino Computer Graphics PolyTrans: A software for converting between different 3D formats. - LKSoft IDA-STEP: Provides tools for viewing and analyzing STEP files.

Additionally, there are online platforms and mobile applications that allow users to view STP files without the need for full CAD software: - eMachineShop Online STEP File Viewer and offer web-based solutions for viewing STP files. - Autodesk Fusion 360 also has mobile versions for iOS and Android, enabling access to STP files on mobile devices.

Before the development of the STEP file format, sharing 3D models between different CAD systems was often problematic, as each program had its own proprietary format. The STEP format has greatly simplified this process, allowing for easier and more efficient collaboration across different platforms and software.

In summary, STP files are essential in the world of 3D modeling and CAD, providing a standardized way to store and exchange detailed object data. This capability is crucial for efficient workflow
