.SZA File Extension
What is an SZA file?
An SZA file contains a CAD drawing created by ISD Software HiCAD, a program used to design 2D or 3D drawings for engineering-related industries. It may store a 2D or 3D model, which includes one or more parts or assemblies. SZA files allow users to close drawings and re-open them to modify them again.
HiCAD is used for designing products in the plant engineering, metal or steel engineering, mechanical engineering, and sheet metal processing industries. The SZA file is the default format for storing products designed by HiCAD. The drawings are typically opened using HiCAD but they can also be opened using the free HiCAD Viewer program.
