If this option is checked, this causes OMICS Rx-Universe to substitute add power for cylinder power in the base curve selection charts. This option changes the meaning of the top line of the base curve chart to be add instead of cylinder (for example, Shamir uses this method of base curve selection for their freeform designs). In this scenario, cylinder power has no effect on base curve selection.
If this option is UNchecked, OMICS Rx-Universe will use a standard base curve chart, with cylinder across the top, and sphere down the side, but will add the add power to the sphere power if the sphere power is plus (greater than 0). Thus, an Rx of +2.00 sphere, -1.00 cylinder, with a 2.00 add, would use the entry in the chart for a +4.00 sphere, -1.00 cylinder.
For an Rx of -2.00 sphere, - 1.00 cylinder with a +2.00 add, OMICS Rx-Universe will use the chart entry for -2.00 sphere, -1.00 cylinder (the add is not considered because the sphere power is minus).
If “Use BRS to get BC from DS” flag is used to get the base curve selection from the DS engine, then the “Subs Add for Cyl” flag has no effect.
Center Design – if this design is automatically centered to frame center on the blank (as with Shamir designs), or if you wish the design to be centered for frame center on the blank (as with IOT designs), check this box. When checked, this causes OMICS Rx-Universe to assume the design is centered on the frame center when calculating minimum blanksize, and will cause the IOT VCA label “_DECM” to be set to 1, indicating that the design should be centered for the FGC. Note that Epson-Seiko does not support centered designs (as of this writing). This optimizes the blank, and results in the smallest possible blanks being used for jobs.
