Volume

This command calculates the volumes of the selected meshes.

The computed volumes are displayed in measures and a measure is created for each mesh.

Select one or several meshes and launch the command.

Different configurations can be used:

If you select one closed mesh before launching the command, you will be able to compute either the volume of the object, or the volumes over and under a water level.
If you select several closed meshes, a window appears showing the volume of each mesh. Measures are also created.
If you select an open mesh, you will not be able to compute its volume, but only the volumes over and under a water level.
If you select two open meshes, you will be able to compute the volumes of embankment and excavation between them.

You can choose the unit in which volumes are computed.

Volumes can be:

positive if the normal is oriented outside.
negative if the normal is oriented inside. Note that you can use the contextual menu to reverse the normal.

In the case of meshes which are not closed, the calculation should be interpreted as an approximation.
