Editing in the Plane of the Screen

Figure (plane-top1): A Top View of the Coordinate Axes

When MGED is in a ``translate'' mode within an edit state, the plane of the mouse or data tablet is mapped to the plane of the screen, to permit moving objects in a controlled way in two of the three available dimensions. The orientation of the plane of the screen is determined by the currently selected view. In most circumstances, users will find that repositioning objects is easiest when the the plane of the screen is oriented in an axis-aligned view. This is most easily accomplished by utilizing one of the preset views. For this exercise, obtain a copy of the axis.g database, and run MGED, eg:

$cp cad/db/axis.g .
$mged axis.g
