BHMS has been used in many engineering applications including design evaluation for ease of maintenance and compliance with customer specifications.

Customer specifications required that a small mechanic (approximately 50th percentile stature female and 5th percentile stature male) be able to remove and replace a component located beneath the cargo floor of a transport aircraft. BHMS was used to demonstrate that the small mechanic can reach the fasteners and can physically perform the required maintenance actions. In addition, BHMS' Collision Detection feature was used to verify that the component could be removed and replaced without any structural interference. BHMS provided for electronic demonstration of the maintenance task electronically, thereby eliminating the costs and cycle times associated with construction of a physical mockup and maintenance demonstrations with human subjects.
