1 - Inside left width 2 - Inside right width 3 - Footing thickness 4 - Inside depth 5 - Wall thickness 6 - Slab thickness |
InsideLeftWidth - Distance from the center cardinal point to the extreme left cardinal points.
InsideRightWidth - Distance from the center cardinal point to the extreme right cardinal points.
FootingThk - Footing thickness of the trench.
InsideDepth - Inside depth of the trench.
WallThk - Wall thickness of the trench.
SlabThk - Slab thickness of the trench.
