Dynamic Section Updating
The most productive method of designing and fairing a hull surface is to interactively move the control points that define the surface. An important aspect of this method is the ability to see the hull shape change in real time as the control points are moved.
RhinoMarine allows you to watch the stations, buttocks, and waterlines in a surface update dynamically as you edit the hull surface. The section locations are defined using RhinoMarine's Sections function. While you are actually dragging one or more control points, the dynamic sections are being computed by RhinoMarine from a surface mesh, and you may adjust the density of the mesh to control the smoothness of the curves. Once you put the control point down, Rhino re-computes the sections in the usual fashion, using the tolerance settings that you have defined in Rhino's Properties dialog. All sections with the Curvature Graph displayed will have the graph recomputed and displayed when put the control point is put down.
First, define the section locations using RhinoMarine Sections command. You can define stations, buttock, waterlines, inclines, cants, and diagonals, by specifying specific locations, spacing, number, etc. Once in the Sections table, RhinoMarine will create the sections as Rhino contours through the surface(s) that you have selected.
Next, turn on Dynamic Sections in the
RhinoMarine menu, or click on the toolbar icon:
When you select one or more control points and drag them, all of the sections will update dynamically. The dynamic sections are drawn in white, so you can visually compare them to the unmodified sections.
