Thinking about doing a LDCad 1.7 version

Should it be a straight find-&-replace for that text? Doing this, it complained that getPos was a nil value.

Sometimes I forget the rules of my own scripting api

getRef does work with groups but it might have a different center, so in the end it shouldn't matter as long the group's center is also on the same x (or whatever plane coordinate) as the other items in the selection.

Otherwise it shouldn't even run the calculation as the first line stops the execution if there are less then 3 items in the selection.  This would be true if one of them were a group while those where excluded.
