Making hull in MaxSurf

Hi,
I have a Napa file for a ship hull (.n2x) and Wonder if it is possible to import this into MaxSurf. It don't seem to be possible directly, so maybe via another program or in some way convert the file.

 

Probably somebody who use Napa can make IGES file from n2x? Then you can import IGES. I don't think you can do something with this file without Napa.

 

Yes you can export an IGES file from NAPA and that file can be imported into Maxsurf. Napa creates a whole bunch of surfaces between each of the master control curves so you will have lots of surfaces in your model. This means its not useful for design modification or fairing but it should be OK if you want to do stability, resistance or motions analysis in Maxsurf.

 

There is only one problem: sometimes I saw gaps between Napa surfaces. Will it be a problem for hydrostatics calculations? I always replace Napa surface with my own like that: http://msi.as/HullSurfaceRemodeling.aspx

 

It wont be a problem as long as the gaps are "small". Maxsurf Stability joins together gaps in the hydrostatic sections that are smaller than 1-2 mm depending on the size of the design.
