I am encountering an issue with the tables I have rebuilt, specifically for ductwork.
For galvanized materials, I have established breakpoints based on both size and wire gauge, which function as intended. However, for other materials, the breakpoints are determined by size alone. My initial expectation was that setting the gauge column to zero would allow the system to reference the cost in that column, but this does not seem to be the case.
Is the only solution to create separate breakpoint tables, one for Size/Wire Gauge and another for Size/None, or has anyone identified a more effective approach to this issue?
