MultiSurf Relational 3D Modeling for Marine and Industrial Design

MultiSurf is a rich and versatile system for parametric design of 3D geometric objects, particularly complex objects involving freeform curves and surfaces. Aerohydro is a complete computer-aided design (CAD) package with the ability to create freeform surface shapes that in other CAD packages are either difficult to create or not available at all.

Precise control of complex shapes:

• Accurate, durable joins between surfaces
• Parametric variation: MultiSurf updates the entire model when you change underlying objects
• A surface for every purpose: 30 surface types let you use the right surface for every aspect of your design (NOT limited to NURBS like other applications)
• Fairing tools: curvature profile and surface curvatures displays help you refine your design.

Viewing and editing:

• Multiple wireframes and rendering windows of one or more models; any viewpoint. Dynamic viewing.
• Drag and drop points; use snap increments, grid. Dynamic update during dragging lets you see in real time the effect on the model of moving a point
• Use filters, layers, and show/hide to aid viewing and selection
• Display original curve or surface for comparison
• Scale, shift, rotate model (or parts of it) in any direction
• Unlimited levels of undo/redo

Add-on programs available:

AHVPP (velocity prediction)
HYDRO (calculation of flotation and righting moments)
MSDEV (flat plate expansion)
Flattener (compound plate expansion)
