This plug-in will register a node and a command. With the command it will be possible to query the volume of a mesh and with the node you can query not only the volume but also the surface area of all the faces.
- Extract the content of the .rar file anywhere on disk.
- Drag the meshInfo.mel file in Maya to permanently install the plugin.
By setting the constructionHistory argument to True, instead of the volume being returned as a float, the meshInfo node will be returned that in order can be used to query the volume.
