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 converter can both convert from and to STEP files and our developers are working to improve our STEP conversion tools in future versions.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.

Our STEP conversion tool can convert most 3D geometry including mesh vertices and faces with no loss of detail. Any color materials contained within the 3D model file will be converted where possible.

Are textures supported in the STEP conversion?
