8.6 INTERSECTION-4 POINTS
Calculate intersection point of two lines which
are formed by four points
St P1/End P1
: The start/end point of Line 1
St P2/End P2
: The start/end point of Line 2
[CALC]:
Calculate the coordinate of the
intersection point.
[SAVE]:
Save the coordinate
8.7 VOLUME
The system will create a triangulation network
based on the points in the list, and take the
reference height as the reference plane to
calculate the volume.
