Command Line Example
The information is based on the current display setting and is calculated from the lines between points one and two, two and three, and from three to one. The command then computes and displays the area.
The following example shows a valid entry using the Inverse Points command when units are set to feet:
NE 1 100 100
NE 2 100 200
NE 3 50 150
INV PTS 1 2
POINT 1 NORTH: 100.0000 EAST: 100.0000 ELEV: <Null>
Distance: 100.000 Course: N 90-00-00 E
POINT 2 NORTH: 100.0000 EAST: 200.0000 ELEV: <Null> 3
