用CAD设计的经典星舰：舰桥与28个活动部件

Build a detailed CAD model of a classic 1960s-style starship with a saucer section, a secondary hull, a connecting neck and two long engine nacelles with glowing copper-orange ends. Give it a pale grey hull with panel lines, a registry number and name painted on the saucer and nacelle, and a thin red stripe along the hull. Design it as an assembly of separate parts, around 28 of them moving, including a captain's bridge and a few interior areas, and keep the geometry clean enough to be 3D printed. Then render a cinematic fly-around of the finished model: a slow orbit past the saucer, a side pass along the nacelles, and a top-down pull-back, all set in front of a blue planet and a starfield. Open with a title card and close with a end card. Deliver the CAD files plus the rendered video of about 30 seconds. Done means the proportions read as the iconic ship from every angle and the camera moves are smooth.
