Preview Viewer



The foundation of PREVIEW’s capabilities is PREVIEW Viewer, VSE’s simple and easy-to-use product for visualizing and manipulating STEP files.

A key novelty of PREVIEW is not only in providing a variety of new capabilities, but also in a generalized approach to communication between a central interface and external software systems or databases that house information regarding geometry, component specifications, and board specifications.  In order to provide an open solution, PREVIEW leverages the STEP protocol, which is a common and extensive protocol for archiving and visualizing a variety of types of data, including all elements of PCBs and PCAs.
