Normally, the program assumes all coordinates to be relative to the current
UCS. The following functions convert points between UCS and WCS.
w2u(p1) Converts point p1 expressed in the WCS to the current UCS.
u2w(p1) Converts point p1 expressed in the current UCS to the WCS.
You can use w2u to find the WCS origin in terms of the current UCS:
w2u([0,0,0])
