Cushion & Bedding Auto-Generation

Auto-compute deviance (measured − design) and judge each point for pipe-base cushion, bedding and pipe seat inspection.

Deviance = measured − design. A point passes when its allowable-low ≤ deviance ≤ allowable-high. Allowables are preset from GB50268-2008 and may be edited.
