RE: Missing illustration in the 2008 standard
You just addressed what I think is one of the anomolies of the standard. Why talk about fully rounded ends when it duplicates the slot callout of Fig.1-35? Personally I champion use of Fig. 1-35(c) (and Fig 1-27) as the best way to dimension slots for end product and inspection. Fig. 1-35(a) is basically "in-process", and should only show up on manufacturing planning and routings.
I know I'll get disagreement on that one.
WhitmireGT is right in that Fig 1-35(b) is centered to accomodate slot punching, and should be kept for that reason. Off thread topic, I know.
RE: Missing illustration in the 2008 standard
I think 1.8.4 covers it and matches figures 1-27, 1-35b & 1-35c. Fig 1-35a doesn't match para 1.8.4.
To me, based on what it says at 1.4 then when there appears to be a conflict between a figure and the text, I go with the text, so I discourage schemes like 1-35a.
Our of interest in the draft does the equivalent of 1.8.10 just refer to 1-27 or is there no illustration or is the whole para removed?

Figure 1.8.10 is replaced by 1.8.4 Rounded End and Slotted
holes states: ..."using one of the methods shown in Fig. 1-29..." Figure 29 has only one example (was 1-27). Figure 1-29 should have been the same as 1-35 in the Y14.5-1994 standard. The bottom line is the text and figures are all mixed up.
RE: Missing illustration in the 2008 standard
I'd be concerned about possible tolerance build up on the length and I'd think that it doesn't support inspection as well as the other 2 methods in fig 1-35. However I'd love to have my error explained to me.

"a good way to go for Fig 1-35a?" (were talking current 1994 std, not the new draft).
I only use Fig 5-47 for full slots and sometimes Fig 1-35c for open ended (U-shaped) slots, breaking out into the end of a part. I get a lot of resistance from Design who get mad because it forces them to model and dimension slots differently.
RE: Missing illustration in the 2008 standard
1-35a however just seems like bad practice. The tolerance on the width is a factor of 2 dimension tolerances, the distance of centers and the width of the slot so to closely control the length you may end up with excessively tight width & centers. Also it doesn't support inspection as well.

It's not something I can claim to have got a real handle on.
