Colors by operations:

In Tools | Options | Color by operations, you can associate a color with some specific operations (fillet, variable fillet, chamfer, pocket and drilling).

For drilling operation, a second column has been added in order to define a different color for the different drilling types.

- If the drilling operation is ticked into the first column and one type of drilling is also ticked in the second column, the color used is the one defined into the second column for this specific drilling type and the color defined into the first column for any other drilling types.

- If one drilling type is ticked into the second column and the drilling operation is not tick into the first column, only this drilling type will be colored.

- If the drilling operation is tick and not any drilling type is ticked, all the drilling types will be colored with the same color.
