LANG
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. IfNL1= 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-P3with tangent to lineP1-P2atPHIT. If 0 (default), the generated line is tangent toNL1toward end P1; if 90, the generated line is perpendicular toNL1. If 180, the generated line is tangent to NL1 toward end P2.ANGcan be any value, but is adjusted to the corresponding acute angle with respect toLOCAT. 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
PHITin terms of the ratio of the distance along the line (NL1) to the length of the line.LOCATcan range from 0 to 1. IfLOCATis blank, the point will be located with less speed and accuracy, and an arbitrary location may result.
Notes
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.
