For modeling purpose , I always use Rhinoceros. I built this model in Rhino and exported to Maxsurf. Usually that always works. I check the model by checking the area of the model and also check the model in Maxsurf Stability in Body plan section (Show single hull section in Body plan). In both of the cases I saw the following error
As you can see the error can be clearly seen. How do I correct the error inside maxsurf? I tried different ways of exporting the model from Maxsurf but the error is persistent.
Hi You must ensure that the surfaces are correctly trimmed or bonded - really it is not recommended to model in Rhino and then import into MAXSURF - you are creating a lot of extra work for yourself!
For correct hydrostatics, you must ensure that any cross-section through the model results in closed, non-intersecting and non-self-intersecting contours. this is described in some detail in the manual.
Hi Pat . Thanks for the answer. But I usually do my initial modeling with Rhino and a lot of times we rebuild hull from existing Lines plan. Some hull shape does have weird shape so Rhino helps to confirms the authentication of hull. So if I build the hull in Rhino then it a lot of work to make it work. Sorry I am new to maxsurf. Do you have any tips If I import the hull surface to Rhino. Is a direct import better. I see Maxsurf can directly import Rhino surface or Via IGES better ? Help me out here.
The best way is to learn how to use the MAXSURF Modeler and do the design there :-) There is a fundamental difference between the dynamic surface trimming in MAXSURF and the static trimming in Rhino and IGES. In MAXSURF we maintain a relational model of the surfaces and its list of cutting surfaces and curves so that if either the main surface or its cutting surfaces are modified, the trimming updates automatically - This information is not available in IGES nor in the Rhino file format. So if you import from either you will need to redo the trimming. IGES or Rhino really doesn't make a great deal of difference because the NURBS surfaces are the same either way!
