$ R2 D4 q7 p# S& {Description
Creates a point at the intersection of two previously defined objects. A reference point must be specified to indicate the desired point in the case of multiple intersections of the two objects. The intersection is determined by looking down the z-axis of the WCS.

Parameters

PMOD2
8 g% x- [% s# b0 I# P5 y2 x8 l# a2 D: H8 z A two dimensional positional modifier which may be used to indicate which intersection to use when multiple intersections exist. The direction is in reference to the work coordinate system.
/ z2 o" D4 D: D5 W8 L- J
point
; I' Z0 p& c2 C' ^* B3 X Reference point, closest to the desired intersection, which may be used instead of the positional modifier, when both objects are curves. If the desired point is the intersection of a curve and a surface or plane, a previously defined point must be used.

A positional modifier is used to assign a reference point. This calculated reference point may not yield the expected results.
+ E; Q! ^' c7 u, m. e( L$ }) S' H/ ?
INTOF
) z0 r9 j# M  u7 l; u Minor word that indicates that the point defined is a unique intersection of two objects.

2 L* {9 R+ S& ^$ J9 Kobj1,obj2
Two existing objects which are not parallel in the work view. Object one must be a curve. Object two may be a curve, face, body with a single face, or a plane.

IFERR,label:
Specifies label to which program execution jumps if no intersection is found.
