Sets elevation and extrusion thickness of new objects.
ELEV controls only new objects; it does not affect existing objects. The elevation is reset to 0.0 whenever you change the coordinate system to the world coordinate system (WCS).
The following prompts are displayed.
The current elevation is the default Z value for new objects when you specify only X and Y values for a 3D point.
The elevation setting is the same for all viewports regardless of their user coordinate systems (UCSs). New objects are created at the specified Z value relative to the current UCS in the viewport.
