The ability to seamlessly switch between solid and surface technology provides unlimited freedom, ensuring the user can work with difficult CAD data. Closing a surface model to produce a solid body eliminates construction problems later in the design process and immediately brings the benefits of solid modelling to the user. To ensure the new surfaces are within tolerance, the new and the old surfaces can be compared to check for min/max distance and curvature deviation. Where surfaces are corrupt or missing VISI will automatically create the edge curve geometry making it easy to rebuild new faces using the comprehensive surfacing suite. Small gaps between surfaces on imported models can be automatically healed preventing the time consuming process of rebuilding very small surface patches. The physical interaction of model geometry can be detected and the results of complex mechanisms validated - ideal when checking for potential collisions with slides, cams and lifters. The motion study simulation tools allow the user to define timelines which control the start & end movement cycles for various groups of components. The kinematic options include constraints to simulate the physical movements of gears, gear racks and rails. Practical applications include springback for sheetmetal, product design changes and geometry healing.
Model editing includes bending, twisting, stretching and deformation, which allows the CAD operator to define the start and end geometrical conditions to drive any model change. The Advanced Modelling tools are capable of deforming geometry while maintaining model integrity and holding curvature up to G4 constraints - This is particularly important for parts of high gloss (black, white, chrome) or that have aerodynamic requirements. Advanced Modelling provides technology that will benefit all users in every industry sector. These modelling commands combined with advanced surface editing make it easy to heal imported geometry or construct the most complex 3D data.Īdvanced Modelling - Deformation. Surface modelling functions include ruled, lofted, drive, sweep, n-sided patch, drape, tangent, draft, revolved and piped surfaces. Surfacing technology however provides a different set to tools and techniques for more organic, free-form geometry creation. Solid modelling commands include boolean technology such as unite, subtract, extrude, revolve, sweep, cavity, intersect and hollow. Solid modelling has become a fundamental cornerstone of design but is often limited to prismatic or basic geometry. VISI provides a dynamic structure from where it is possible to work with either solid, surface, wireframe or a combination of all three without any restrictions. Very large files can be handled with ease and companies working with complex designs will benefit from the ease with which their customer’s CAD data can be manipulated. The ability to skip corrupt records during the import process provides a platform from where the most inconsistent data can be managed.
The extensive range of translators ensures that users can work with data from almost any supplier. VISI can work directly with Parasolid, IGES, CATIA, Creo, UG-NX, STEP, Solid Works, Solid Edge, Inventor, ACIS, DXF, DWG, JT Open, STL and VDA files.
Combined with Hexagon’s surface technology, model analysis and 2D design, VISI Modelling offers complete flexibility to construct, edit or repair the most complex 3D data. VISI Modelling is the foundation of all VISI products and provides a robust and powerful solid and surface modelling system based around the industry standard Parasolid® kernel.
