- Apr 16 10:51 AMThanks for the help -- I'll look tonight.
I was thinking no undo because this is a one-time function, but you
are reminding me I need a warning before-hand. The function needs to
be able to work on a section of the map -- think of taking an
Icosohedral projection & changing it to a pseudo-Mercator -- you'd
work on each of the points separately (and as I'm envisioning it,
work on the left side of each separate from the right)
I think that point-items like symbols should be moved over, based on
the position of their reference point.
