The STP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STP files are text-based formatted files containing one instance per line.

Although STP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.

STP Converter Capabilities

Our STP 3D Model/Mesh tool does not support any color material data contained within STP files so the converted file will not contain any color information.

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.

As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.

Information for converting from STP to OBJ

Your STP file will be converted to a OBJ 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.
