Priority Rating with Multi-Tier Exterior Walls

If the first construction layer in a multi-tier wall represents the exterior side, it should be given the highest priority rating – this will ensure that the manner in which the various tiers intersect at corners is calculated correctly.


Legend:
1 - 4	Direction in which straight wall is entered
A	Exterior wall’s priority ratings: Layer 1 = 600 Layer 2 = 500 Layer 3 = 400
B	Exterior side
C	Offset direction to the side (in this case to the right)
