Rossford Posted January 22, 2016 Share Posted January 22, 2016 The file bloat thread got me thinking about simplify poly tool. I use it a lot, but basically did trial and error to see what looks good, i.e., good smoothness over lower points. I understand the "maximum distance" method okay. I tested several landscape, free form shapes from 1/4 to 4 Acres, plus a few contour lines (all drawing in polyline, converted to polygons) It seems like the vertices on the polygons come in spaced anywhere from 0.5-2 feet apart. One polygon had a perimeter of 2875 feet, and 2875 vertices. Its a matter of picking how much straightening you can tolerate. My visual tolerance before they become too blocky is about 5-10 feet, depending on shape complexity. My question is, how does VW calcuate "Maximum Deviation" and what does it mean? I tested the same area polygons and it seems like the max deviation was like 0.25-1' max to get the same result..... Quote Link to comment
ericjhberg Posted January 23, 2016 Share Posted January 23, 2016 I would also love to hear an explanation of this topic. I often do the trial and error thing because I don't really know what I am looking to accomplish or what differing parameters will do to the polyline. Quote Link to comment
