Starting in Rhino 8

[GioMun]

Hello!

 

I´m quite new in this section, so please be patient. 😌

 

I´m at the moment trying to start the art of 3d modeling our models in Rhino. Just as a form to understand the models that sometimes don´t have a good plan/drawing, and you have to take care of that (i hope you understand).

The problem is that i don´t know how to start. I have found a few tutorials on the web, but i´m having problems with generating surfaces ,curves, so, i´m still at the beginning!! 

 

I see those pencil-like drawings that some of you make and i hope to achieve that some day! It reminds me when i started on this hobby at all.

 

My question is that is there any tutorial, made for shipmodelers, that would allow, eventually to achieve those drawings i was talking about?

 

Thank you very much!!

 

Greetings.

You should follow all the Rhino tutorials until you are proficient with basic surface modeling and 3D construction, From there you can start constructing basic 2D plans into a wire frame 3D object.

Thank you for the answer.

 

Yes, that is what i´m trying to do right now. I´m looking at every YouTube tutorial i can find.

 

I know that is the way!

 

I was asking if there where any more specialized tutorial out there.

 

Thank you.

Draping surfaces, constructing basic shapes and learning the tool functions will lead you right into modeling ships.

 

Theres likely some marine focused ones. I’m also sure there’s plenty here on MSW. Lots of people are 3D modeling ships on here.

I have had positive results with DELFTShip.   There are some great tutorials on that as well.

 

Finding out if everything is not absolutely aligned, the surfaces can track wildly since the curve control points are not linear.  The farther one is away from the tangent the wider the swing.  When done in a traditional 3D solid modeling surfacing program can lead to lumpy patterns.  For most of this modeling the fewer control points the better.  So I have been going back and forth between the 2D drawings and DELFTShip.   Depending on the scale  single pixel on a low res scan can represent 1 to 3 inches or more on the model.    I think this process is called fairing. 

 

There is a lot of rinse and repeat when tracing over things.

 

DELFTShip can export STL.  Which can then be imported into the Solid modeling program.   It also comes with an online database of 100s of ship hulls.  These are interesting to look at to see where the control points are placed.    

 

The paid version can export IGES, which is probably overkill for the sort of simple modeling done.  Since we are not doing dynamic simulations.
