In this tutorial we will work with Serie 60 ship, from the Iowa University. The tutorial is aimed to show how to work with a symmetric monohull ship.

Loading geometry

Introduction

FreeCAD-Ship works over Ship entities, that must be created on top of provided geometry. Geommetry can be a set of surfaces or solids, but following criteria must be taken into account:

  • Only symmetric ships are supported yet, so only half starboard geometry must be provided.
  • Starboard geometry must be included at negatives y domain.
  • Origin (0,0,0) point is the Amin frame and base line intersection.

Loading Serie 60 geometry

In order to help new users FreeCAD-Ship includes an example geometries loader.

Executing the tool (Ship design/Load an example ship geometry) a task dialog will shown. Select Serie 60 from Iowa University and press Accept. Tool loads new document with s60_IowaUniversity geometry.

Now you are working over example file, in order to preserve example is strongly recommended to save as new file before edit nothing

Create ship instance

In order to create a Ship instance select s60 geometry and execute the ship creation tool (Ship design/Create a new ship).
