5) four points to construct intersection point and angle
Purpose:
to measure four points from two lines to construct
the intersection point and the intersection angle
of the two lines.
Example: the point A and B in the line 1 ;
the point C and D in the line 2 ;
to construct the intersection point and
the intersection angle of the line 1 & 2
1. Press the
key to enter into four points
to construct the intersection point and
the intersection angle function
L1 PT.1
message window displays
requesting enter the point no. 1 of line 1
2. located the cross hair centre to the position A of line 1, press
to enter the point.
