Anyone has the same experience that the shape of polygon changed automatically with some processing. For example, a perfect circle changed to n-gon shape, n can be between 3 to 7. a round ending road changed to a sharp point. it happened right after i did some processing, such as split, update. The data looks ok with merge method.
Do you have any idea what happen on my data, and how can i get ride of this trouble. thanks.
You are probably using a relatively coarse cluster tolerance and/or resolution. Per my experience, unless you have a REALLY good reason to, you should endevor to use the ESRI defaults:
Geoprocessing tools generally default to the most coarse tolerance/resolutiuon. So if you union a FC at 10ft tol with another at 1ft tol, the output will be a 10ft tol (unless you specify otherwise in the tool GUI or the tool's envr. settings).
