4. Create Strip Solids

To cut the pit solid into strip solids, the pit solid and the strip surfaces are used as inputs to the Create All Closed Volumes tool:

Again, since the strip solids do not inherit the Strip attribute values from the input strip surfaces, the Set Attributes by Direction tool is used to increment a Strip attribute value for each strip solid:

At this point, the Apply Colour Set tool and the Colour Set Wizard can be used to colour the strip surfaces by Strip attribute.
