With the ShipWeight Visualizer Rhino plug-in you can do visual sanity checks during estimation and monitoring.
The plug-in displays center of gravity and extension in 3D for all parts of a vessel in a ShipWeight database. There are two modes of display: Line-display and box-display. Line-display shows center of gravity and extension of all items in each direction, box-display shows center of gravity and a ‘bounding-box’ defined by min and max values of LCG, TCG and VCG (if available).
When displayed as lines, extensions can be displayed even if values for one or two dimensions are undefined. You can also simulate min and max values for undefined dimensions, and then you can also visualize items as boxes.
You can select a particular item by clicking on it or by selecting it from a tree-view. The item is then highlighted and information about it is displayed in a window. By filtering on weight classes or individual items you can choose which items to display when rendering.
To use the Rhino Plugin you just need Rhinoceros 3D installed. Download an evaluation version here - just add your email and country.
