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

Although STEP 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.

STEP Converter Capabilities

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

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modelling applications such as Blender, 3D Studio Max and others due to its 3D animation capabilities.

The format is used to contain 3D models which includes vertices, faces and other 3D geometry along with animation data. The format is proprietary however there is a publicly available API to use for development purposes. The file contents can be either text or binary and work has been carried out by the Blender Foundation to document the format.

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.
