A STEP without datums can still get an AI sketch quote. That sketch is not a locked inspection plan. For position or profile control, add datums or name the locating faces.
Preview the quote with no account. Sign in to save or order. Complex parts: 12h target on Dongguan business days (UTC+8). Quantity 1 can come back with datums added.
QA docs are optional. Lead time splits production and freight. No implants. A missing datum is not replaced by an unpublished certificate number.
