I think Star Trek was able to do it because it was the only show with an accurate-ish model kit which could be used for such things. MCA-57 (aka post Star Wars ILM) also did this for Battlestar Galactica, notably the Cylon hangar populated with Monogram kit Raiders in "The Hand of God"....Star Trek broke ground using its own licensed products (AMT kit) in the production--something ILM would do years later in the production of The Empire Strikes Back.
I think the protoApogee exILM group withdrew from GALACTICA after the initial 7 hrs (pilot plus 2 2parters), so the rest of season 1 was done by Universal Hartland.
I'd never heard of the MCA-57 moniker before. Is that referenced in a lawsuit or an onscreen credit?
The history is covered on the Universal Hartland webpage (link).
