Masking Complexity Estimator

Count the features that must retain their as-machined or protected condition. The result is a drawing-review category, not a price or lead-time promise.

Protected-feature counts

Transparent rule: threads ×1, bores ×2, faces ×2, datums ×2, passages ×3, and markings ×1. Scores 0–4 are low, 5–11 are moderate, and 12 or more are high review complexity.
