Volume Menu

The Volume menu has some optins for measuring the volume between a set of surface patches and a plane, or between two surface patches. It also contains some options for editing meshes by trimming to a plane or removing selected triangles.

Interacting with the plane

For the plane to be visible "Display Plane" needs to be selected. This should show a plane with one side red and one side green. The plane position can be altered either interactively or by setting parameters directly. To set the parameters directly choose "Set plane" and you are presented with a dialog to set the translation and rotation (the rotation is applied first in the order z then y then x, apparently). The set the plane interactively select "Move plane" from the menu, shift+right click and drag will rotate the plane, ctrl+right click and drag will shift the plane.
