James, I just watched the video to try and hear what I said. I remember making that comment after having a discussion on the beta forum while testing the software. There was a question about the cursor details. One of the testers was asking about what each value represents because it was sort of unclear. At that point we still had the height measurement (you see it in this video because it was made with an earlier version of the software). We were told in that conversation that height would be taken out of the software and the number we want to look at in the cursor details is the material thickness. I relayed that info. That being said, after testing it for a bit, I mainly look at fissure height now. I believe that material thickness is measured in a straight line from where your cursor is until is hits the prep. this can be affected buy the angle that the model is in. I believe fissure height is measure from the path of draw. the other reason I mentioned it here was that if you look at the fissure height on the inlay, it is .01 mm. Obvioulsy that is not the case. I had to use my thickness measurement to then determine if I had enough thickness in the bulk of the restoration and also where to find that .01 measurement on the fissure. Turns out, this .01 measurement tends to happen from time to time with inlay or onlay preps as the fissure approaches the cavo surface margin. Sorry for the confusion in the video.

Hi Rich--nice video.You mentioned that the programmer said not to worry about the fissure height parameter.My problem has always been in Biogeneric,that the fissure height always seems to be too low.I always have to raise the fissure to at least 1.5mm for emax.So we should not worry so much about fissure height,but rather the thickness parameter.I seem to be always raising and virtually grinding,which does take time.Thanks--Jim
