ProSurf is a powerful application created for the designers that need to create 3D ship models. The program deals with relational trimmed NURB curve and surface 3D modeling. The program is customized for the design of any type of boat or ship and can be used by both professionals and sailing enthusiasts.

FEATURES:

· Full trimmed NURB curve and surface 3D modeling
· Point, line, polyline, NURB curve and NURB surface entities
· Curve entities can include both polyline and curve sections
· Edit points lie ON the curves AND surfaces
· Automatic symmetrical design option
· Full relational editing of connected surfaces or polysurfaces

Dynamically updated geometry constraints allowed:
· Attach points to curves or surfaces
· Merge points together
· Fix points relative to other points
· Attach curves to surfaces
· Bond surfaces edges
· Attach surface edges to middle of other surfaces
· Draw and update ruling lines between curves
· All related geometry dynamically updates and moves during the editing process
· CreateBoat Wizard to create a starting shape of a vessel using simple input of principal dimensions
· Constraints or relationships are optional and can be added or deleted at any time - they are independent of the entities
· New curves or polylines can be attached directly onto a surface in one step
· Curves on surfaces can be edited and faired like any other curve
· Curves on surfaces can be used for trimming and be dynamically dragged
· Dynamic Move, Move%, and Ooch Point commands for detailed shaping and fairing of Class A surfaces
· Smoothness indicated with dynamic curvature curves on curves, surface rows or columns, and planar cuts
· Smoothness also indicated with Gaussian and Mean surface shading
· Full DXF and IGES input and output, including IGES types 143 and 144
· DXF and IGES input options and report
· STL output for trimmed NURB surfaces
· Text file input and output compatible with spreadsheets
· Input and output of NWS, GHS, SHCP, OFF, and Michlet offsets file formats
· Easily fit offsets files (GHS, SHCP, etc.) with NURB surfaces
· Fast, dynamic display of plane-surface and surface-surface intersections while editing shapes

2D shapes can be easily created and positioned using many methods - enter sizes or interactively dragged to fit:
· Triangles
· Rectangles
· Trapazoids
· Arcs
· Circles
· Ellipses
· Polygons
· NACA airfoils
· UIUC airfoils (from 1000+ airfoil database)
· Full set of curve and polyline tools for detailed shaping
· Insert and delete points on curve/polyline
· Edit using points ON the curve (2 styles) or edit the vertex points
· Curvefit of polylines
· Refit curves - equal spacing, add points, cull points
· Toggle curve or polyline edit points to/from hard, knuckle points from/to smooth curve points
· Closed, periodic curves allowed
· Join and break curve commands
3D bonded solids can be automatically generated and edited:
· Triangle solids
· Box solids
· Wedge solids
· Cylinders
· Cones
· Truncated cones
· Spheres
· Ellipsoids
· Solids can have different sizes, positions and orientations at the ends
· Solids can be truncated, solid, or hollow like a pipe, with a user-defined thickness
· Cylinders, cones, spheres, and ellipsoids can be full 360 degree revolution or any user-defined range of angles
· Solids can be fully capped off and bonded to create "watertight", editable geometry - even partially revolved solids
· Full set of surface tools for detailed shaping
· Create surface by picking 4 corner points
· Add/delete surface rows or columns anywhere
· Split a surface into two surfaces at any internal row or column - surfaces remain bonded and editable
· Combine two surfaces into one at a bonded edge
· Bond or un-bond common surface edges
· Edit using points ON the surface (2 styles) or edit the vertex points
· Surface extrusion - straight path or to a point
· Surface sweeping - using one or two paths - the shape curve is normal to the path curve or normal to surface
