KBETW, KP1, KP2, KPNEW, Type, VALUE
Creates a keypoint between two existing keypoints.
KP1First keypoint.  If KP1 = P, graphical
picking is enabled and all remaining command fields are ignored (valid only
in the GUI).
KP2Second keypoint.
KPNEWNumber assigned to the new keypoint. Defaults to the lowest available keypoint number.
TypeType of input for VALUE.
RATIO  | —  | Value is the ratio of the distances
between keypoints as follows:  (  | 
DIST  | —  | Value is the absolute distance
between   | 
VALUELocation of new keypoint, as defined by Type (defaults
to 0.5).  If VALUE is a ratio (Type =
RATIO) and is less than 0 or greater than 1, the keypoint is created on the
extended line.  Similarly, if VALUE is a distance
(Type = DIST) and is less than 0 or greater than
the distance between KP1 and KP2,
the keypoint is created on the extended line.
Placement of the new keypoint depends on the currently active coordinate
system [CSYS].  If the coordinate system is Cartesian,
the keypoint will lie on a straight line between KP1 and KP2.
 If the system is not Cartesian (e.g., cylindrical, spherical, etc.), the
keypoint will be located as if on a line (which may not be straight) created
in the current coordinate system between KP1 and KP2.
 Note that solid modeling in a toroidal coordinate system is not recommended.
