Sometimes when I am tracing out a deck if I happen to have "Snap" turned on I will discover after the fact that
one of the edges of the deck is not actually at 0 or 90 degrees but that the 'Snap" function has actually snapped
to something unwanted thereby leaving me with a deck edge that is slightly off square - maybe 0.75 or 89.3
degrees or some such thing. Without redrawing the whole deck again is there a simple way to straighten the
affected edge to back to where it is supposed to be i.e. 0 or 90 ?
