= shift =

Compiled by EP

== Description ==

Shift will adjust a entire shape file into by a deltaX, deltaY and deltaZ.  It is typically used to adjust the center of figure to center of mass.  

It can also deal with the fact that sometimes a shape model's center of figure can drift off of the 0,0,0 coordinate center, i.e. the middle of the asteroid is no longer at the origin of the system.  The typical way to do this is to run [[shape_info]] and use its Center of Figure offsets as the input for shift.





== Input Files ==
 * <shapefile>.TXT
 * [[MAPFILES]]
 * [[LMRKLIST.TXT]]


== Output Files ==
 * [[LMKFILES]]
 * [[MAPFILES]]
 * <shapefile>.TXT


When shifting a shape file, you give it only the root name.  You do not put in the fullpath or .TXT

The last 5 lines are designed to copy and paste to update the rest of the system (updated the [[SCOBJ]] and [[C_vector]].  You need to do this if you update the MAPLET positions.
