Hi, @keerthana. I would defer to @DavidRutten or @kike on this one. There are many discussions in the forum about this topic–at least related. From what I briefly found by searching, GH1 takes its tolerance setting from Rhino, though you can control the display of GH1 tolerance from File > Preferences > Display (in GH1). Personally, I have not used GH2, yet. There has also be a suggestion to add tolerance per component (which David thought was a bad idea/visually cumbersome) and others have proposed maybe adding a tolerance setting to the group component.
