point sop- how to access specific points

OK,

say I have a simple rectangle. I want to use the point sop to access / manipulate individual points. the points are named 0,1,2,3. or are they?

in the first field of the point sop properties is the “Group” parameter. From the wiki-

$PT< - The point number

If i plug in $PT2 i am seemingly accessing point 0. any other number i try ($PT0, $PT1, etc.) does nothing.

any clues?

just put the point number in the group, i.e.: 45

$PT is a variable holding the current point number. It gets filled when the SOP loops over all points in its input and for each point, the current point number is assigned to this variable.

that did the trick!

thanks
