Description

Create a New Ship or new Ship Instance.

Ship works over Ship entities, that must be created on top of provided geometry. Geometry must be a solid, or set of solids, following criteria must be taken into account:

  • All hull geometry must be provided (including symmetric bodies).
  • Starboard geometry must be included at negatives y domain.
  • Origin (0,0,0) point is the Midship section (Midpoint between after and forward perpendicular) and base line intersection.

Usage

In order to create a Ship instance (in other words, a New Ship), select the hull solid geometry and execute the ship creation tool Ship design → Create a new ship

Creating ship task dialogue and some annotations at 3D view will shown. The annotations will removed when you close Ship creation tool, so don't worry about this.

Most relevant ship data must be introduced (Ship uses a progressive data introduction system, so basic operations can be performed knowing only basic ship data, more information is needed as the operations become more complex).

Ship data

Main dimensions must be introduced here:

  • Length: Length between perpendiculars.
  • Beam: Total ship beam.
  • Draft: Design draft.

Front view annotations

Length annotations

Usually the Length between perpendiculars depends on design draft, so if you don't know what is the length of your ship you can set draft, and fit length in order to get bow and draft intersection.

Side view annotations

Beam annotations

Same process is valid for Beam fit. Note that the requested value is the total beam, but just the annotation on starboard side is shown.

When you press Accept button, a new Ship instance named Ship is created at Tags & Attributes dialog. The geometry is not needed anymore, so feel free to hide or remove it.
