VISI Modelling

CAD & Modelling

True Hybrid Modelling — No Boundaries Between Methods

Most design workflows don't fit neatly into a single modelling paradigm. VISI removes those constraints entirely, allowing designers to freely switch between solid bodies, surface patches, and wireframe geometry — sometimes within the same operation — without workarounds or file conversions. Solid modelling handles prismatic and engineered forms with precision. Operations include Boolean unite, subtract, intersect, extrude, revolve, sweep, cavity, and hollow commands, giving engineers a comprehensive toolkit for manufacturing-ready geometry. Surface modelling extends those capabilities into the organic and free-form. VISI supports ruled, lofted, driven, swept, n-sided patch, drape, tangent, draft, revolved, and piped surface creation methods — each available for both original design work and the repair of imported data. Together, these environments form a seamless hybrid workspace where no geometry challenge is off-limits.

Advanced Modelling & Deformation

For parts that demand more than standard geometry editing, VISI's Advanced Modelling toolkit provides deformation-based modification while preserving curvature continuity up to G4 — critical for high-gloss surfaces (black, white, and chrome finishes) or aerodynamically sensitive components. Deformation operations include bending, twisting, stretching, and freeform reshaping. Operators define start and end geometric conditions to precisely control the outcome of any change. Typical use cases include springback compensation in sheet metal, design iteration on complex product forms, and geometry healing for clean downstream processing.

Kinematic Simulation

VISI's kinematic tools let engineers define constraint-based motion studies to simulate the real-world behaviour of mechanisms before any tooling is committed to steel. Gear, gear rack, and rail constraints are supported natively, and timeline-based controls allow users to choreograph multi-component movement sequences. Interference detection flags potential collisions between moving elements — including slides, cams, and lifters — so problems are identified and resolved at the design stage rather than on the shop floor.

Surface Repair & Geometry Editing

Imported CAD data rarely arrives in perfect condition. VISI addresses this with automatic gap-healing for small surface discontinuities, eliminating the need to manually rebuild tiny surface patches. Where surfaces are entirely absent or corrupt, VISI reconstructs edge curve geometry as a starting point for new face creation using the full surfacing toolkit. New surfaces can be validated against original geometry using min/max distance and curvature deviation analysis, ensuring repairs are within tolerance. Closing open surface models into solid bodies early in the design process prevents issues from compounding downstream. The ability to fluidly transition between solid and surface environments means complex or problematic imported data can always be resolved — no matter which format it originated from.

Powerful Blending Options

VISI supports a wide variety of blend types including constant radius, variable radius, disc, hyperbolic, and elliptical — all applicable directly to solid models. Blends can propagate along tangent edge chains for rapid application across an entire component. For difficult blending scenarios or inconsistent geometry, blend faces can be constructed as untrimmed surfaces for maximum flexibility, then trimmed back using wireframe curves, edge data, or adjacent faces.

3D Curves & Split Lines

VISI provides a complete library of 3D curve types: iso-parametric, cross-sectional, helical, elliptical, spiral, hyperbolic, and additional mechanical curve forms. Theoretical and manufacturing split lines can be generated directly on the model. Advanced editing tools allow tangency forcing, periodicity control, control point manipulation, and curve extension or joining. Multi-curve reprocessing combines operations to streamline the creation of high-quality geometry for surface construction, trimming, or downstream CAM use.

Ease of Use

VISI is designed to be productive from day one. Logical menu structures, icon-based commands, and context-sensitive help reduce the learning curve for new users. Dynamic navigation — including rotation, zoom, and pan — combined with customisable function keys and programmable mouse buttons help experienced users work at full speed. Unlimited undo/redo with user-defined bookmarks gives designers the freedom to experiment and backtrack at any point. Multi-layer and multi-origin management, with customisable colour palettes and line styles, keeps complex assemblies organised and easy to navigate. All project data is stored in a single file, simplifying data management and eliminating version confusion. Running a single software session with full simultaneous access to all components makes assembly-level editing straightforward and efficient. High-performance rendering, live texture mapping, and dynamic cross-sectioning make large assemblies easy to visualise and review before committing to manufacture.

Automated 2D Drawing Creation

VISI generates complete 2D drawing sets directly from the 3D model with minimal manual intervention. Fully editable orthographic and isometric section views, automatic dimensioning, and hole type/position tables are created associatively — meaning a change to the 3D model automatically updates the corresponding 2D views and dimensions. Individual component details can be extracted from any part within an assembly and presented as a mix of rendered 3D views and traditional 2D draughting. Standard catalogue components display correctly in section views. Parts list tables and balloon references can be added using the built-in assembly management tools.
