[Mi...] Posted November 9, 2023 Share Posted November 9, 2023 All, Per the snap shot of datum C, its referencing the inside wall of a slot. Only thing is this is the back wall is one end of a slot. The cut thru is through the center of said slot. How do I make the back wall of the slot datum C? I can make the diameter into a cylinder but of course that moves my Y cord to the center of the Cyl. Would I be better off making a 3d line centered in the slot and scan from top to bottom of the center outside radius? If this doesn't make sense let me know I can drop in more screen shots.

[Da...] Posted November 9, 2023 Share Posted November 9, 2023 Please sign in to view this quote. Wouldn't in this case datum C feature just be a line (2D)? Link to comment https://qualityforum.zeiss.com/topic/6852-datum-structure/#findComment-27878 Share on other sites More sharing options...
[Jo...] Posted November 9, 2023 Share Posted November 9, 2023 How is Datum C used? How certain are you about the feature ? If the leader is attached to the surface, a F.O.S it could be the entire wall which could constrain 5 D.O.F and all positions of the sockets..

[Mi...] Posted November 9, 2023 Author Share Posted November 9, 2023 I meant a 2D line yes I mis typed C is only used for location apparently as the print shows no dimensional are called back to C. Well there is one a TP of a plane back to ABC but that's about it crazyyyyyy dwg Link to comment https://qualityforum.zeiss.com/topic/6852-datum-structure/#findComment-27882 Share on other sites More sharing options...
