Thanks kindly to everyone for their comments, I greatly appreciate this. I realize there is quite a variety of backgrounds on this forum, and alot of talent here in developing wonderful sketches and concept drawings !
OSTexo: This is the start of a detailed design project. There is a need to come up with an initial concept which could be assessed from a naval architecture perspective. Don't have any naval architects to help me at this stage. Given cruise ships have been designed and built for some time now, from small to mega size, there is an expectation generic models are available and could be used, corresponding to a given size category, in terms of lightweight, GT, length. However finding a suitably sized model that could be imported into an analysis program, is where I don't have leads. What will happen in due course is that a naval architect will create their own concept model to meet the performance requirements. Just in dire need to get something initial developed.
Micheal Gibson: Thank you very much for these suggestions. That model at grabcad.com looks like a great lead ! I'm trying to figure out how to convert those kinds of models into useful formats for naval design concept analysis.
Pilou: Thank you for your feedback on this. There is alot of talent here to create detailed sketches ! Wow. The thing I would like to determine is to what extent could one take a sketch based model, done in .dae format, and convert it into a useful file that could be used for initial hydrostatic & hydrodyamic analysis, hull design. A NURBS model would be a good bet it seems. I tried to export a mesh model from AutoCAD into a format useful for hull design, but ran into some problems. Could Rhino be a reliable route ? I have not tinkered with it before.
