Learn how to create, open, and convert STP Files, the most popular 3D CAD file format.
STP, or STEP, is a file extension for a 3D graphic file used by CAD software. Files with the STP extension are usually 3D model files created in the STEP file format. STP files may also use the less common STEP file extension.
STEP is short for STandard for the Exchange of Product Data. It is the ISO 10303-21 standard for representing 3D objects. The STP File Format is used to distribute 3D CAD files that can be viewed by a variety of software applications.
The real strength of STEP is its popularity. It is the most popular 3D CAD file format that allows designs created by different CAD programs to be viewed and modified. It is one of the most popular formats for 3D CAD data exchange and file sharing. STP files are primarily used for transferring 3D graphics between different CAD and CAM systems.
STP File Format
The STEP file format was released in 1994 to standardize sharing of 3D CAD data. The file format is defined in ISO 10303-21. The file extensions STP and STEP indicate that the file contains data conforming to the STEP ISO standard.
STEP file format is widely adopted by many CAD software. The format is an ASCII format, making it very easy to read. However, there are a few disadvantages of the STP File Format –
- The file format specification is not free, you have to pay for it.
- It is not possible to sequentially read a STEP file. The entire file has to be read into memory before parsing.
- The format is not storage-efficient or well-defined. There are several ways to write an entity.
- Many CAD software does not support the full STEP format specification. As a result, some sort of “Repair Geometry” is required after each and every import.
How to create STP files
Most STP files are exported from CAD software. All popular CAD programs, like SolidWorks, CATIA, Creo, NX, Solid Edge, and Autodesk Inventor, have an option to save CAD parts and assemblies into the STP file format. This feature may be optional in CAD programs, and users may need additional licenses or purchase a higher version of the software to export to STP.
Glovius PLUS users can export their CAD parts and assemblies to the STP file format. PLUS users can also export to IGES, Parasolid, and 3MF. Glovius PLUS is available for $
720 $576/year per subscription. Glovius PLUS permanent licenses are available for $1395 per node-locked license and $2795 per floating license.
