The free ModelPress System provides a mechanism for publishing 3D files to a web-ready format, as well as a flexible, visualization application that can be embedded in other desktop applications or in web pages for web-delivery and viewing. ModelPress Publisher reads native 3D CAD model files including SolidWorks 2003 and Inventor 6. Publisher then compresses the model assembly, creating a secure, non-editable ISF file that is viewable by the free ModelPress Viewer. ModelPress Viewer views the highly-compressed ISF files created by ModelPress Publisher. It can be a standalone desktop application or be embedded in another desktop application; or, it can be embedded in custom web pages to be a web-delivered control. Designed to work with Microsoft Internet Explorer 5.0 or higher.
