VISI Modelling - Powerful Surface Modelling & Solid Modelling
Software
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.
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.
Extensive range of CAD interfaces
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. The extensive range of
translators ensures that users can work with data from almost any supplier. The ability
to
skip corrupt records during the import process provides a platform from where the most
inconsistent data can be managed. 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.
True hybrid modelling
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. Solid
modelling
has become a fundamental cornerstone of design but is often limited to prismatic or
basic
geometry. Solid modelling commands include boolean technology such as unite, subtract,
extrude, revolve, sweep, cavity, intersect and hollow. Surfacing technology however
provides
a different set to tools and techniques for more organic, free-form geometry creation.
Surface modelling functions include ruled, lofted, drive, sweep, n-sided patch, drape,
tangent, draft, revolved and piped surfaces. These modelling commands combined with
advanced
surface editing make it easy to heal imported geometry or construct the most complex 3D
data.
Advanced Modelling - Deformation
Advanced Modelling provides technology that will benefit all users in every industry
sector.
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. 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.
Practical applications include springback for sheetmetal, product design changes and
geometry healing.
Kinematic Simulation
The kinematic options include constraints to simulate the physical movements of gears,
gear
racks and rails. The motion study simulation tools allow the user to define timelines
which
control the start & end movement cycles for various groups of components. 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.
Surface repair and editing
Small gaps between surfaces on imported models can be automatically healed preventing
the
time consuming process of rebuilding very small surface patches. 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. 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. 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. The ability to seamlessly switch between solid and surface technology
provides
unlimited freedom, ensuring the user can work with difficult CAD data.
Powerful blending
Constant radius, variable radius, disc, hyperbolic and elliptical blends can be
constructed
directly onto a solid model. Blends can be propagated along tangent edges to quickly
sweep
across a component. For very complex blending conditions or when working with
inconsistent
data, blend faces can be constructed as surfaces in an untrimmed state providing greater
flexibility. Trimming is easy using either wireframe curves, edge geometry or existing
faces.
Full range of 3D curves and split line curves
Create a theoretical split line curve or construct 3D curves including iso-parametric,
cross
section, helix, ellipse, spiral, hyperbolic and other mechanical curves. Advanced curve
editing provides the ability to force tangency / periodicity, move control points, join
or
extend curves. Combined curve reprocessing allows multiple command combinations to
greatly
simplify the process of creating high quality curve geometry for surface construction,
trimming or machining.
Ease of use
Simple menu and icon commands with context sensitive on line help make it quick and easy
to
start using VISI. Dynamic rotation, zoom and pan, together with programmable function
keys
and mouse buttons help speed up the operation of the software. Unlimited undo and redo
operations with user definable bookmarks enable the designer to move backwards and
forwards
throughout the design process. Multi layer and multi origin control with user definable
color pallets and line styles makes it easy to review, create and work with very complex
designs. All information is stored in a single file providing easy access and reducing
the
burden of data management. Managing one session of the software with all the components
available for editing at the same time provides much greater flexibility. Super fast
rendering, texture mapping and dynamic sectioning make it easy to visualize CAD files
and
large assemblies.
Automatic creation of 2D views
A complete set of 2D detailed drawings can be generated directly from the 3D model. This
includes fully editable 2D and isometric sections views, automatic dimensioning and hole
type and position tables. Individual details can be created from any component in the
assembly and displayed as a mixture of 3D rendered and 2D drawings. Any standard
catalogue
component will have the correct detail representation within a section view. A change in
the
3D model will result in a modification to the 2D view along with any fully associative
dimensions. Parts list table items and their respective balloon references can be added
to
the drawing using dedicated assembly management tools.
Manufacturing modules
All the VISI applications run in one easy to use environment with knowledge based
modules
available for mold tool and progressive die design. Once the tool design is complete,
machining of plates can be completed using feature recognition; drilled hole features
and
apertures are automatically selected with the correct drilling cycles and 2D milling
routines applied. For 3D forms, mold cavities or forming stages on a progressive die,
VISI
Machining will create the toolpaths directly on the model incorporating conventional,
high
speed and 5 axis toolpaths. Keeping the model within the same product environment
throughout
the entire project, from design to manufacture will guarantee data consistency and
greatly
smooth the design process.
Due to the integrated nature of VISI, manufacturing of individual plates can be
completed
using feature recognition. Drilled hole features and apertures are automatically
selected
with the correct drilling cycles and 2D milling routines applied. For more complex forms
VISI Machining can be used to generate both conventional and HSM cutting toolpaths.
Complex
punch apertures and the corresponding solid punches are easily manufactured with
seamless
integration to Wire EDM.
