Locating the physical placement location of a plurality of brackets on a patients study cast includes obtaining an array of data points from a study cast and generating a virtual model of a dental impression from the array of scanned data points, Individual teeth from the dental impression can be manually severed or “cut” and manually dragged from a start position to a finished position to determine a treatment plan. The orthodontist virtually marks the position on the virtual model where a physical bracket is desired. A marking device physically marks a physical model with the corresponding bracket locations. The physical model can serve as a template or guide to locate brackets for an indirect bonding style tray.
