What is a CZD file?
A CZD file is a CAD document created by The Crash Zone or another CAD Zone software product. It contains a 3D model of an accident scene, crime scene, or other emergency situation. CZD files are used for sharing crash and other emergency diagrams that evaluate and influence road, site, and building construction.
CAD Zone software products are used by crash investigators, firefighters, accident reconstructionists, law enforcement officers, and others.
