Drawing surfaces of the bulb in Rhino

[toda]

Could you help me someone how can I create surfaces of bulbous with Rhino if I have 2D drawing in AutoCad. Thanks forward

Depends what type of geometry you've used in Autocad. Rhino can import just about anything AutoCAD can make. Depending how you've defined the thing in autocad, you might Loft it (if you have a series of stations), NetworkSrf it (if you have plan, profile, edge curves), Revolve it (if it's got some degree of cylindrical symmetry), etc. Rhino can generate a surface in a lot of different ways, what works best depends on how you've defined your 2D entities.

I have sections and also plan and profile. But problem to me is I can't do the end of the surface because of they have some arcs when go to the center line

I am not sure I understand the problem, but you might try importing the sections to Rhino, then
create planes at the correct station spacing,
project the appropriate station to the appropriate plane,
use the loft comand to create the surface.
Why don't you post the geometry you have. Then I bet someone will come up with a logical method to make the 3D model

there are many good tutorials for Rhino.
I like this onel

from

Sometimes it's useful to draw the bow profile and rotate around a vertical axis a few degrees of you have a boulb and a rounded bow, then match and merge this surface with a lofted hull a bit firther aft, and then adjust with nudging of the control points.

Thanks for all
Here you are I send here in the attached file 3 views of the project: Body, profile and plan. Could you see and give me some advices. Thanks

Toda, did you read the tutorial from Rhinocentre in Netherlands?
It's not the only way to model a hull, but it explains very well how to control curvature and shape for curves and surfaces.

I'll have a look at your dwgs later.

I have seen this tutorial but I don't understand how I can drawn three sections on fore of the ship (not bow's center line ?)
