Roughness
Roughness captures surface texture requirements extracted from the drawing. It records the applicable roughness standard, whether material removal is required, prohibited, or optional, the direction of lay, any machining allowance, and whether the symbol applies all around the contour. The individual requirements (such as Ra or Rz limits) are stored as a list of RoughnessCondition objects, and an optional RoughnessWaviness carries waviness controls. The raw label and a confidence score are preserved as well, together with any manufacturing process noted on the symbol, so CAM or quality teams can plan finishing operations, support quoting, and highlight surfaces that require grinding or polishing to meet specifications.
