Here is a design tip I like to use when working on anterior cases. I always take a pre-op Biocopy image of the existing condition even if I'm not copying it direclty. I designate the case as Biogeneric individual and then add a Biocopy catalog in Acquisiton.
From there, I can use the Biocopy overlay to help determine my midline and incisal edge position. We've taught this before at our workshops, but I'm using another feature to help show the patient a nice before/after prior to milling.
In the design phase I will group the restorations together.
Next I can turn OFF the upper jaw catalog in Display Objects and turn ON my biocopy.
Now to give the patient a nice before/after view I simply toggle on/off the Restoration button in Display Objects to alternate between pre-op and design.
