After defining a quadrilateral, all nodes within it can be assigned new depths. Select the action required from the following dialog box:
-
"Assign default depths"
The default depths are assigned. This alters the depths at the selected node for all planes. -
"Raise active plane by dz"
The depths of the selected nodes are raised by the value dz given for the active plane. -
"Set active plane to z"
The depths of the selected nodes are set to the depth z given for the active plane.
