Marine Weight Schedule - User Manual

Introduction

Marine Weight Schedule is a plugin for Rhino 3D, designed to generate a bill of masses and inertias from a vessel’s 3D model. It take in account points, curves, surfaces, solids and blocks, and use the parameters from the layers names to apply the unitary/lineic/surfacic/volumic masses, with a margin percentage applied.

A command is also provided to generate an hydrostatic report at a given height interval (based on Rhino hydrostatics features)

Both reports will be generated as excel files (.xlsx) based on a customizable template, but microsoft excel doesn’t need to be installed on the computer.

Plugin installation

The plugin installer can be downloaded at: https://www.tomkod.com/product/marine-weight-schedule/

To install them, you just have to drag/drop the file “Tomkod.rui” to a rhino window.

Features and commands

MWS_About

Todo

ProjectWeightReport

Computes the whole model masses and generates an excel report.

Walkthrough

Model preparation

The whole model or worksession will be used. The layers should be named following this pattern: MyLayerName (Mass) %Margin% |VerticalOffset| , where:

  • Mass will be the ponctual/lineic/surfacic/volumic mass
  • Margin (optional) will be the percentage to add to the object's mass.
  • VerticalOffset (optional) will be the the vertical offset to apply to the layer's masses

Output

An excel report is generated: A custom ViewPort is created with the gravity center displayed:

Options

No option available.

Customization

The excel file template can be modified in the plugin's install directory.

HydrostaticReport

Computes an hydrostatic analysis at different heights and generates an excel report.

Walkthrough

The hull's surface or polysurface is selected as input. Once validated, Rhino's hydrostatic culculation is runned at various heights as defined in options, and an excel report is generated.

Options

TEMin Minimum height (mm)
TEmax Maximum height (mm)
Delta Distance between two tested height (mm)
Density Water Density
AutoMinMax Detect TEMin and TEmax values from geometry (Only available when a geometry is selected)

Customization

The excel file template can be edited in the plugin install directory.

GBlock_GetList

Lists every existing GBlock names and masses to the command line.

GBlock_SelectNextMissingData

Select the next block in the document where gravity center and mass are undefined

Walkthrough

Todo

GBlock_SetData

Add gravity center and mass informations to a block. GBlocks are considered by the command ProjectWeightReport , which makes them extremely useful for your equipements.
