Eaves was introduced to Herman Zimmerman through Eaves' friend Phil Edgerly. Zimmerman was looking for someone to put together a display of Enterprise, and Eaves drew up a plan for the display. Zimmerman was impressed by the artwork, and asked Eaves to join his design team for Star Trek Generations.[6]
After the work on Generations ended, Eaves returned to his work constructing fibreglass models. When an job became available on the Star Trek: Deep Space Nine art department during season four,[2] Zimmerman invited Eaves to join the team.[6] At the time, Eaves was working on a Boeing 747 model for the film Executive Decision.[3] Eaves spent the next twelve years working on one incarnation of Star Trek or another.[6] During this time, his work included the designs of the Phoenix, the Enterprise-E and the Vulcan ship from Star Trek: First Contact.[2] The initial model of the Enterprise-E was constructed by Eaves.[7]
His design work featured in the Deep Space Nine episode "Far Beyond the Stars", during the part of the episode set in the 1950s.[3] After working on Star Trek: Insurrection, where his designs included the Son'a vessels, Zimmerman brought Eaves onto the team behind Star Trek: Enterprise as Production Illustrator.[2] Whilst working on that series, he started work on the Enterprise (NX-01), as well as the Suliban vessels.[8] His work on the final TNG film Star Trek: Nemesis included the design of the Reman starship, the Scimitar.[9]
