LANG, NL1, P3, ANG, PHIT, LOCAT
Generates a straight line at an angle with a line.
NL1Number of the line to be hit (touched by the end of the new
line). If negative, assume P1 (see
below) is the second keypoint of the line instead of the first. If NL1 =
P, graphical picking is enabled and all remaining command fields are ignored
(valid only in the GUI).
P3Keypoint at which generated line must end.
ANGAngle of intersection of generated line PHIT-P3 with
tangent to line P1-P2 at PHIT.
If 0 (default), the generated line is tangent to NL1 toward
end P1; if 90, the generated line is perpendicular to NL1.
If 180, the generated line is tangent to NL1 toward end P2. ANG can
be any value, but is adjusted to the corresponding acute angle with respect
to LOCAT. See "Notes" for
a discussion of accuracy.
PHITNumber to be assigned to keypoint generated at hit location (defaults to lowest available keypoint number [NUMSTR]).
LOCATApproximate location of PHIT in
terms of the ratio of the distance along the line (NL1)
to the length of the line. LOCAT can range from
0 to 1. If LOCAT is blank, the point will be located
with less speed and accuracy, and an arbitrary location may result.
Generates a straight line (PHIT-P3)
at an angle (ANG) with a line NL1 (P1-P2). The
location of PHIT on the line is automatically calculated.
Line P1-P2 becomes P1-PHIT and new lines PHIT-P2 and PHIT-P3 are
generated. Line divisions are set to zero (use LESIZE,
etc. to modify).
PHIT is positioned closest to LOCAT for
the given angle, ANG. To ensure better performance,
it is recommended that LOCAT be input, even if
it is 0.
The program uses an iterative procedure to position PHIT.
The procedure is not exact, with the result that the actual value of ANG will
sometimes differ slightly from the specified value.
