  • You can get creative and make your own ruler function that stores off your ruler points in a global variable. Then you can undo the rulers by clearing them all and recreating all rulers except the last one.

    procedure(myRuler(@optional (cv geGetEditCellView()))
        unless(boundp('rulerHistory)
            rulerHistory = makeTable("rulerHistory" nil)
        )
        pts = enterLine(?prompts list("Point to first point of the ruler" "Point at the next point of the ruler") ?wantPoints 2)
        leCreateRuler(geGetEditCellView() pts)
        rulerHistory[cv] = cons(pts rulerHistory[cv])
    ) ;proc

    procedure(clearMyLastRuler(@optional (clearAll nil) (cv geGetEditCellView()) )
        leHiClearRuler()
        if(clearAll then
            rulerHistory[cv] = nil
        else
            rulerHistory[cv] = cdr(rulerHistory[cv])
            foreach(pts rulerHistory[cv]
                leCreateRuler(cv pts)
            )
        )
    ) ;proc
