CubeCAD is a full 3D CAD environment that allows you to move your mouse to any arbitrary point in the three-dimensional coordinate space. A work plane is the plane on which the mouse cursor is located and moves freely around. When you start the [[EM.Cube]] application, the mouse always moves on the XY plane, meaning that the XY plane is your default work plane. In addition, [[EM.Cube]]'s "Snap-to-Grid" mode is enabled by default even though the project workspace's grid is not displayed by default. As you move the mouse around, it snaps to the invisible grid points. This provides a convenient way to draw objects with precise dimensions and at precise locations. The coordinates of the current location of the mouse are reported in the Status Bar.
