AeroHydro MultiSurf 8.8.402.0 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.
