HOW TO SMOOTH OUT POLYGON SS3

I found how to reduce the collinear  vertices in a  polygon by accident a while back, just copy move parallel positive and repeat but same distance negative to reinstate the polygon in its original position, you can even use a reference file and copy into the active to prove it does retum in its original location.. I don't think its deliberate but rather a quirk that has a real benefit once you know about.... don't know if this works in CE...

Much more efficient than delete vertex one at a time see my example below
