ANDOVER, MASS. - Matra Data-vision Inc. in Andover recently released new products to enhance design capabilities. Matra introduced its Strim version 6.1, which contains features for quick and accurate checking and automatic clean-up of imported surface geometry files.
The Strim three-dimensional data exchanger module has special capabilities for easing the data recovery process, and provides for automatic checking of data syntax to prevent erroneous launching of a long conversion process on corrupted files. It corrects model data regardless of the entry path and can be an independent complement to 3-D interfaces like IGES, VDA, SET, SPAC and Unisurf.
The ``geometry quality checker'' option gives the user interactive control of surface defects that are disclosed by means of tolerance criteria. Holes, gaps and tangency misalignment, as well as duplicated or overlapping entities, are displayed on screen. It also can be used to guarantee model integrity before sending the file from Strim to another system.
Strim's surface healing feature automatically fills the gaps between surface patches without adding new entities to the model data. It mathematically ``stretches'' existing patches to obtain a tight surface, giving improved surface quality with less work for topological operations, computer numerically controlled machining and analysis.
The surface healing feature was designed for plastics and tooling specialists, and cuts preparation time for tasks like milling, stamping, stereolithography file generation, or mold manufacture.
Matra also recently introduced Prelude Design on Windows 95, which includes an advanced solid modeler, complete drafting and documentation capabilities, photorealistic rendering, and data exchange in one software package.
Prelude Design builds complex, 3-D solid parts and multicomponent assemblies with fast, dimension-driven editing capabilities based on Matra Datavision's Adaptive Modeling technology.
Recently, Matra and Moldflow Pty. Ltd. of Shelton, Conn., announced a partnership that will combine Matra Datavision's Strim surface modeling and manufacturing system and the Moldflow Dynamic analysis and design optimization products.
Moldflow will offer Matra's geometry quality checking tools as an option to the Dynamic product line, and Matra will embed the Moldflow MF/Flowcheck in Strim. The two firms will offer services from design and analysis to mold building/machining to manufacturing. The partnership covers operations in the United States, Canada and Mexico.
Matra Datavision offers software programs including those for concurrent engineering environments, mold-making solutions, product quality verification and computer-aided-design data sharing.
Matra, founded in 1980, is part of the Lagardre Group headquartered in Lesulis, France, a $10 billion company.
