Back at work. We also have that 3D photo active. We have not much paid attention to that. If you think that it is easier to edit ROI without 3DPHOTO: after you have acquired reference capture, from treatment side bar 1) select surface display and 2) deselect 3D photo. Then 3) Edit ROI. Seems to work on the fly on AlignRT treatment view also. I have to add here that Advance quick start quide book is great. It is very informative, practical and clear. Likewise is the version 6.2 as well. ALL the AlignRT users here in Tampere thinks that 6.2 is SIGNIFICANTLY easier and more pleasant to use than the previous one.
