Importing model from Rhino to Multisurf

There are several ways to import a 3D model from Rhino to Multisurf, each with it's advantages and drawbacks.

• If you need to import a surface with a big precision and further using it for 3D modeling in multisurf (eg. importing the hull surface of a boat and using it to make a deck or superstructure), you should use the *.iges format file. This will import the surface with the specified tolerance as a single surface.
  • Note: You will have to make sure that the surface doesn't have trims, because *.iges files do not support trims.

• If you want to import the surface from Rhino to use it in module hydro is better to use the triangle mesh system(*.raw). For this format u can specify in Rhino the number of polygons for the mesh, which in the end will generate the tolerance of the imported model.
  • With this type of file the surface will be broke in a number of triangle which will approximate the initial surface.
  • Also this tipe of file supports trimmed surfaces, being useful if you want to see the influence of the superstructure(which is made of many small trimmed surfaces) for the hydrostatics and rollovers charts.
