i want to design yacht hull in rhino and than want to export it to maxsurf… which tools in rhino i should use to make my yacht hull(Like loft, edge surface tool) or some other philosphy of modelling, so that i can avoid
trimmed surface problem, while opening that file in Maxsurf…please helpNote: attached file showing messed up surface cz of trimming problem in Maxsurf software
Another thing you should not do.
The work path is Do in Maxsurf then go trim in Rhino. Then go back to Maxsurf to calculate Speed and stuff.
If you go from Rhino to Maxsurf, especially if you use “bad” commands in Rhino you will end up with surfaces with thousands of control points in Maxsurf, making them impossible to edit and manipulate.
Do not use Patch, Use Loft. Try avoiding trimming, create your surfaces such that no trim exists.
The problem there is you get U and V parallel at a surface corner (point 3) - operations involving offsetting, like OffsetSrf and filleting will be unhappy. I would avoid this structure for working in Rhino.

Hi Pascal,
Don’t look at my sketch as a surface with 4 control points at the corners. These are just the corners. In my experience this is the best way to create ship’s hull.
Fillet is not used there. As for the OffsetSrf, it is fine to the necessary extent (ship hull thickness) or upto 50mm, if you have done your work properly and you kept the tangency and curvature at that point continuous.
well…the model which i shown…i not used trim tool… .may i know in meantime, like the photos which u shown above…
You want to say…i should not use trim command , instead i should use " movement of point to adjust the surface shape "…Right ivelin.peychev???
Yes, with the right surface this is the way to do it. Like the bottom of the power boat in your other thread
