Hello dear, after a creation of a network-plane - 4 sided rectangle with 8-10 points on each side, I was very happy about the first modifying - I did use only a 1d Movement-direction - but after that I did get hunderd of control points, its too smooth and to difficult to made ne modiffyings. Any way to decrease the points?
