What is a ZEI file?

ZEI files mostly belong to CAD/CAM software. ZEI files are used to store technical drawing information for CAD/CAM applications.
These files are primarily used as CAD drawing files that hold design data needed for engineering or machining. They come in different variants:

CAD Drawing Format – Many ZEI files contain data from systems like Zeichnungseditor that produce drawing and CAD/CAM design files.

ZWCAD Drawing Variant – Some files use the Microsoft Compound File format to store structured drawing information, typical of TRIGA CAD systems.

Cutting File Variant – Certain ZEI files hold instructions for cutting operations, used by centers such as Zünd Cut Center and sometimes linked to ZEISS CALYPSO data. For more details on the cutting applications, please visit Zünd.

FilExt.com tip: These files are vendor specific and may require the appropriate CAD/CAM software to open, view, or convert into common formats like DWG or DXF.
