XVL Technology

Where is XVL used?

XVL is used by thousands of manufacturers worldwide as a means of communicating design, production and manufacturing information which is leveraged by 3D data. With its unequalled compression, XVL allows previously large 3D CAD assemblies to be easily shared, used and manipulated. The XVL Solutions enable the reuse of the 3D data for needs extended across the enterprise including simulation, animation, design review, process design, assembly and process planning, 3D parts lists and creation illustrations direct from 3D.

XVL also supports 3D data in Microsoft Excel, Microsoft Office applications and Adobe Acrobat's PDF.

How does XVL work?

XVL is based on free-form surface representation, also known as a Gregory patch. A Gregory patch is excellent at representing continuity between surfaces. It easily ensures tangent-plane continuity (G~1 continuity) between surfaces. If you have experience in operating spline-series modelers, which support NURBS (Non-Uniform Rational B-Spline) surface, you may understand how difficult it is to modify model shape while keeping surface continuity. XVL's Gregory patch approach easily solves this problem.
