Business Combinations [Abstract]
Acquisitions	Acquisitions During the six months ended July 31, 2017, Autodesk did not complete any business combinations or technology acquisitions. For acquisitions accounted for as business combinations, Autodesk records the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. Autodesk records the excess of consideration transferred over the aggregate fair values as goodwill. The goodwill recorded is primarily attributable to synergies expected to arise after the acquisitions.

For acquisitions accounted for as business combinations, Autodesk records the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. Autodesk records the excess of consideration transferred over the aggregate fair values as goodwill. The goodwill recorded is primarily attributable to synergies expected to arise after the acquisitions.
