I design yachts. While doing this the lifestyle of customer have to be considered. You need to define all parts from the door knob to drain holes on the deck, from the books on their library to the chair they use. It is not only to design but also to show what they will see when it is produced. As a yacht designer, I don't only sell the design of the yacht, but also the interior and exterior details even including the chairs on board. Please note that this is my first job on freelancer website and I see this as a starter job, to get a good review, so please don't hesitate to ask any questions you may have.
I will first complete the drawing in 2d format and send to you for approval on the dimensions. Then I will use Rhinocheros program to make the 3d file. I will prepare the renders and export 3d file in any format you may prefer (dwg, dxf, iges, 3dm etc.)
We can discuss any detail on skype if you are using. Good luck with your choice!
