For example, if a blank has a true curve of 5.92, in 1.53 index, that blank has a radius of curvature of 89.527. Comparing that to the "min r" and "max r" of the block list, block piece 5 will be selected.
To add a new blockpiece or crib group to a grid, right-click on the click, and select either "Add Row" or "Remove row" as appropriate.
When you remove a row in a block selection grid, the minimum radius of the previous row will be changed to match the maximum radius in the current row (to avoid gaps). When adding a row, however, it is the user's responsibility to ensure that the block pieces are correctly described (named), and that the selection rules are correct for the blocks. Rx-Universe WILL allow overlap and/or gaps when block pieces are being added.
