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, Inventor 7, Inventor 8, OpenHSF version 10, EDS Solid Edge v14, Spatial ACIS / SAT, Autodesk AutoCAD DWG files (including 3D ACIS SAT objects), XGL/ZGL (Microstation, Rhino, and others supported by saving to XGL). Use Publisher to 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. In addition to adding Visual Rights security, users can publish files to our encrypted 3DF format, viewable only by the ModelPress Viewer.Designed to work with Microsoft Internet Explorer 5.0 or higher.
