STP files are a 3D file format used to store complex 3D object definitions in a standard format to facilitate data transfer between compatible 3D modelling and CAD (Computer Aided Design) applications. In addition to storing 3D object data, the STP format can store additional information such as materials, tolerances, and other relevant data.

The STP format was first released in the early 1990's, has become a standard for 3D object storage, and is used in automotive, electronics, and other industries. STP files can be opened in most modern CAD applications and can be imported into many 3D modelling applications too.

The file content is ASCII text-based and conforms to the ISO-10303-21 standard. The 3D object contained within the STP file is described using a combination of points, lines, and edges. Due to the format being ASCII text, complex objects can lead to large file sizes. In addition to large file sizes, some complex STP files can take a long time to open within editing applications, even on a high-spec, modern computer.

FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.

The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.

The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modelling applications, such as Blender.

FBX Converter Capabilities

Our 3D conversion tool does not support color/material information in FBX files so your file will not contain any color information.

Information for converting from STP to FBX

Your STP file will be converted to a FBX file using our unified 3D model and mesh conversion tool. Our STP 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your STP file, your final 3D model will contain geometry data only.
