Rhino sectioning & lines plan drawings

Sections in Rhino3d are used for:

• Analysis purposes of fairness and shape of 3d geometry
• 2d drafting and export to for example AutoCAD
• Lines plan drawings

Sections and lines drawings can be made with:

• Rhino3d techniques (contour, section etc.)  
• Orca3d plug-in sectioning and lines drawing feature  
• ArchCut plug-in (free) 
• Grasshopper plug-in visual script tool (free)
• Download the Ship Hull Rhino3d file used in the demo video
  

Rhino3d

Creating sections and lines plan drawings fast and accurate is very simple with Rhino. Commands like section and contour are mostly used.
In order to create automatic updates of sections and 2d drawings the free ArchCut plug-in does a wonderful job.

Orca3d
Orca3d plug-in for naval architects is the most convenient solution and also offers hydrostatics, stability and power and speed prediction features.

Grasshopper
Visual scripting with Grasshopper plug-in is a new and very powerful tool to make Rhino more clever with scripts.

Download a free ship hull script which also generates sections automatically and see a video tutorial.

Grasshopper Parametric Ship Hull Modeling

Parametric hull modeling for concept design requires a flexible and versatile approach. Therefore we are very proud to publish a new way to model ship hulls with a free open source Grasshopper script.

The script we publish over here enables you to model a bulbous bow pram type hull with a press of a button. Other ship types are also possible when you dive into the script and modify it to your needs. Extra functionality can also be added by expanding the script with your creativity. At the moment an automated volume displacement and centre of buoyancy calculation and a real time lines plan is included.

•  Download Grasshopper and find tutorials

This script is the result of a collaboration of the following people from their respective companies and organisations:

• Bas Goris, GustoMSC, started the quest for Rhino hull modeling methods
  
• Phil Shapiro, Cadlantique, presented the loose loft 3d curve technique
• Bart van Oers, TU Delft, put this Rapid Hull Modeling methodology in Rhino Script
  
• Julien le Rouzic, GustoMSC, converted the Rhino Script into a Grasshopper Script
  
• Gerard Petersen, RhinoCentre, added real time lines plan and displacement functionality

For us it is important that you share your experiences, changes and additions to the script. So please send them to us and we can learn from you!
