That looks a lot better haha. Yes, the additional spacing is always the same. We never even open up that drop-down. The reason my CG is as low as it is in my SS is because this was an over-implant that needed a little better retention. Depending on your mill/printer your could need yours higher or lower. If you're used to additional spacing that high, then it's likely this fit might be too tight for your liking, though that is a shallow prep so a little tighter could work in your favor.
I believe the only reason that it hasn't presented itself is because this prep is kind of.. unique looking on the lingual, so it's more likely to show errors. Kind of like dominoes, the more problems there are to start with, the worse it looks down the line. If preps look ideal then other problems appear to be less of an issue.
You're going to want to make a couple of quick prints/mills out of extra material if you have it available to check which settings will work better for you though. On a prep with any length of axial wall, try .05 as a good base (exocad default is .08 which I think is a little loose) and tweak everything in from there.
Good rule of thumb for ideal fits :
* Green "0" cement gap zone will be only on the shoulder/chamfer of the margin. If this goes up an axial wall then you'll find your fits tight until you ream out the crown
* Yellow CGZ will be what you work out to get your fits ideal. For shallow preps, implants, or preps requiring tighter CG, lower this.
* Blue "add another zone" CGZ is what I use to add additional spacing on the occlusion or incisal for a passive fit (you don't want to grind in the top of an inside of a crown to get it to seat, so I have a larger CGZ if my axial walls are tight). I also use the Blue zone to highlight areas I think will cause troubles, like weird lumps, sharp edges, or undercut areas the software has already blocked out but I want it more blocked out. This extra gap is especially important on implant cases since I want the axial walls tight for anti-rotation, but never want to have to grind out that small space in the occlusion in the internal of the crown.
