Geometry or nodes in ANSYS

When creating geometry or nodes in ANSYS, instead of listing and transcribing
coordinate information, use the *GET functions NX(n), NY(n), NZ(n) and KX(n), 
KY(n), KZ(n). For example, to define a new keypoint (101) based on the location 
of some existing keypoints (12, 32 & 45), issue the command
"K,101,KX(12),KY(32),KZ(45)" or put the entries into the relevant GUI boxes. In 
his way, there is no loss of accuracy either.

Similarly, if you need to apply a point constraint or a point load to a keypoint
or node whose number isn't known or whose number changes - due to optimisation
looping, for example - use the *GET functions NODE(x,y,z) and KP(x,y,z). For 
example, to apply a force (12) in the X direction to a keypoint at location
(1.2,2.3,3.4), issue the command "FK,KP(1.2,2.3,3.4),FX,12".
