I'm new to NX, and I've noticed there are two coordinate systems available when locating or constraining geometry or dimensions relative to the origin (or X, Y axes for that matter) - the Sketch and Datum. Is it considered better practice to use one vs the other? I'm been using the Sketch CSYS, thinking that if copy or move the sketch later the sketch CSYS will come with it and constraints made to that will stay intact. But maybe I'm mistaken, so I thought it worth asking the here before creating a bunch of sketches based on that assumption. Also, if you don't use QuickPick, what is the default selection? Thanks!
