RoughnessEvaluationLength

RoughnessEvaluationLength specifies the length over which surface roughness should be evaluated. Drawings state this either as an explicit length or as a multiple of the lambda-c cutoff wavelength, and the model captures both forms: a length with value and unit, or a lambda_c_multiple factor. Recording evaluation lengths helps quality teams ensure measurements comply with ISO or ASME methods, prevents misinterpretation of surface finish requirements, and lets inspection programs configure instruments correctly, providing a basis for automated metrology program generation.

Bases: BaseModel

For sophisticated application, the sample needs to be taken over a longer distances. This is specified the either the sampling length in millimeter (ISO 3012:1974, ISO 3012:1978, ISO 3012:1992) or as multiple of the main lambda (ISO 3012:2002 and ISO 3012:2021).
