There are some great fan-designed 3D models, many very faithful to the original blueprints, that a snapshot could work quite well for a tabletop battle-grid. Credit always goes to the 3D modeler. I only add missing bits and a bit of colour. Search here for the full series.
This Akira-class bridge was designed by the 3D modeler, RedShoulders, for the U.S.S. Cao Mengde. There are some other spectacular interiors for this particular ship, such as a huge shuttlebay.
