In this video, you’ll learn: What the Actual Mating Envelope really is (not the textbook shortcut) How AME differs from MMC, virtual condition, and size limits Why AME is critical for real assemblies, not just inspections How to apply it correctly to ensure parts always assemble in the real world This is essential knowledge for engineers, designers, and quality professionals who want zero assembly surprises and drawings that work in production.
