The auto snap in SewerGEMS SS5 with Autocad, even I checked the boxes in the Autocad (2016)snap but when start drawing the layout I should every time to do (Shift+right click) and chose (for example mid point, center, .... etc.), does any body checked that, I have a thought there is a bug needs fixed, even I tried that with autocad 2015 and got the same failure.
