[QUOTE="DAL Claxton, post: 325817, member: 22777"] Good morning @ PCdental! I want to check first if you are using a material configuration other than the default? Some companies when creating theirs are too used to the wording 3Shape uses. Namely the "additional spacing" verbage. You should leave the additional spacing as .02. The reason this is there is to allow for passive seating. Otherwise, the 0 cement gap green zone would make the crown impossible to seat. Any changes you make to gap should be done by changing the yellow gap zone, or adding in an additional light blue zone. The green 0 CG zone should only really be where you want the marginal seal. That prep is a little odd to start with on the lingual margin, but the huge gap between your prep starting cap and your actual prep is there because of that additional spacing. I'm attaching an example screenshot for you. In it, you can see there is the offset of the .02 where the green 0 CG is. If you increase this gap, then the blocking out set by the undercuts tab tends to get a bit... wonky. *** EDIT : in the undercuts tab, also turn on that protected zone near margin. Otherwise if the Dr. has an undercut to the margin, then you will have a wide open margin because it will block it out all the way down. The protected zone will close the margin the amount you have it set to. I hope this helps! - Josh [ATTACH type="full" alt="Additional Spacing Example.png"]36765[/ATTACH] [/QUOTE]
