ASME Y14.41 - Digital Product Definition Data Practices2019
This Standard establishes requirements and references documents applicable to the preparation and revision of digital product definition data, hereafter referred to as data sets. This Standard defines exceptions and additional requirements to existing ASME standards for using digital product definition data set(s) or drawing graphic sheet(s) in digital format, hereafter referred to as drawing graphic sheet(s). When no exception or additional requirements are stated, existing ASME standards shall apply. It is essential that this Standard be used in close conjunction with ASME Y14.24, ASME Y14.34, ASME Y14.35, and ASME Y14.100.
