The STEP file format, also known as ISO 10303-21, is a 3D file format used within the area of computer-aided design (CAD) as a way to exchange data between different applications. The STEP format is essentially a plain text file containing commands used to describe the 3D object.
Due to the standardized nature of the format, there is support for importing STEP files into many CAD applications. STEP files can, however, become quite large, and some complex files can take a long time to import into a 3D project.
Mesh Geometry
The STEP format is not a mesh-based format; converting a STEP file to a mesh format is possible via most CAD applications via a tessellate function.
STEP Converter Capabilities
As the STEP format currently does not support the use of material colors when used by tool, your converted model will contain only the mesh geometry, material colors will not be transferred to your converted file.

An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.
As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.
Mesh Geometry
Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.
OBJ Converter Capabilities
As the OBJ format currently does not support the use of material colors in 3D models when created using our tool, your converted model will contain only the mesh geometry, material colors will not be transferred to your converted OBJ file.
