Schroff Development Corporation is a software and publishing company founded in 1988. SDC began with the goal of improving the computer-aided design market through the development of three-dimensional design software based on the more realistic and functional tools provided by a system based on solid modeling. SilverScreen, our flagship software product, functions as a standalone solid modeling software product in addition to serving as a development platform on which application products can be constructed. The development platform, referred to as the SilverScreen CAD Engine, provides a powerful set of tools that allows programmers to create custom applications through the construction and manipulation of solid models. The CAD Engine is designed to offer a flexible development environment that meets the product and skill level of the developer. This product currently serves as the CAD and graphics engine for a variety of products requiring fast execution and the ability to handle extremely large models. Products developed using the CAD Engine range from political and demographic maps to 3D designs of residential homes where each construction member is detailed. SDC has provided many companies with assistance in the initial development of their products. This assistance, in conjunction with the goal of making the SilverScreen CAD Engine match the needs and capabilities of the user, provides a development environment that allows an application to quickly reach its market. Our book and software publishing business was developed in response to the need for up-to-date, economical, and effective materials to support the computer-aided design market. We provide published materials focusing on computer-aided design and related software for professional and academic markets. Our books and CD-ROMs, which are available for most major computer-aided design software packages, have been widely adopted for use by major universities and training organizations.Our mission is to be a highly responsive company that provides products and services that meets the needs of the computer-aided design marketplace.
