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
