Relational 3D Modeling for Marine & Industrial Design   




MultiSurf is a rich and versatile system for parametric design of 3D geometric objects, particularly complex objects involving freeform curves and surfaces.

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

Export: DXF, IGES, POV-Ray rendering files, VRML; to AeroHydro programs: MSDEV developable plate expansion, MSPLEX compound-curved plate expansion, HYDRO hydrostatics, OFE offset file editor, AHVPP sailboat performance analysis

Import: DXF, IGES; FL/2B, Autoship, MaxSurf (formerly MacSurf), and FastYacht files.

General calculations:

  • Weight schedule
  • Mass properties
  • Angles, clearance, distance of points

Special marine design tools:

  • Upright hydrostatics
  • Ship lines
  • Offset files

Viewing and editing:

  • Multiple wireframe 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

Documentation: comprehensive, illustrated reference and tutorials, in online help system and printed (over 500 pages).
