In Galahad Compass, the field of view is limited. Because of this limitation, sometimes it is impossible to polish the facet to the target state within 1 step. In this case, the system automatically builds intermediate facets which allow polishing all the facets even if the initial semipolished stone has only one big facet.
Note that after the direction and zero is set for the first sub-step, the system will automatically use the same direction for all following sub-steps. If you need to change the direction manually, you still have the ability to do that: use the Clear button and then set the new direction in a usual way.
For the big step, two or more sub-steps can be created if necessary. When the polishing is divided between sub-steps, the maximum change is always aimed to be within the initial steps, and the remaining tiny one - in the last step.
