I have been hunting for years now, trying to find 3D models (or even some decent side-view graphics) of some of the ships from Doctor Who--particularly those from the post 2005 (so-called NuWho) era--but thus far I've had little success. Sure there are tons TARDIS models out there (along with plenty of Daleks, sonic screwdrivers and various sets), but there is almost nothing in the way of proper spaceships except for a very small hand full of ships from the classic era of Who. Given that Doctor Who is one of the most long-lived and successful "space-based" sci-fi shows of all times--right up there with the likes of Star Trek and Star Wars--its very odd indeed that there hasn't more attention paid to some of the very interesting and unique spacecraft designs seen in this series.
So if anyone has any Doctor Who ship models that they would be willing to share, or knows where I could find some, please let me know. While ANY NuWho ship(s) would be greatly appreciated, I'm especially looking for a 3D model (or even a usable orthographic side-view render or schematic-type drawing) of the Cyberships seen in the opening scene of the episode "A Good Man Goes to War".
You are right in that Doctor Who is not a "ship-centric" series. While spaceships in Doctor Who are common enough, they are seldom the focus of attention, which is probably why you don't remember most of them. More often than not, the ships in Doctor Who are simply places where stories happen. Consequently, we're seldom given any specific details about the ships, their technology or tactical capabilities beyond what is absolutely relevant and necessary to the plot of an episode.
That said, I could name off AT LEAST a couple dozen ships and space stations just off the top of my head that have appeared in Doctor Who episodes over the past 9 years, more than half of which were featured fairly prominently in their respective episodes--at least as much as the typical "ship-of-the-week" on Star Trek. Yet unlike with Star Trek (or Star Wars, Stargate, or Battlestar Galactica, etc.), where there are 3D models, side-view renderings and/or schematic-type drawings for virtually every ship to have ever appear on the show, no mater how obscure the ship or brief its appearance, there is simply no equivalent treatment given to the ships of Doctor Who--not even for the most obvious examples, such as the Dalek saucers. As I said before, this seems extremely odd to me; and its more than a little frustrating.
You asked what I'm wanting the models or images for. Well there are a number of applications I could name, but the single biggest reason I'm looking for them is to add these ships to my ever growing, ever expanding sci-fi size comparison chart that I am building (patterned after Jeff Russell's brilliant STARSHIP DIMENSIONS website, with well over 1000 entries at last count, and well on its way to being the most comprehensive compilation of its kind). In terms of quality, I don't necessarily require super-hi-res, super-detailed, super-accurate images for what I am doing. Higher quality is, of course always preferable when possible, but ultimately as long as the image is reasonably accurate and recognizable I'm happy.
As to the Sketchup models at 3D Warehouse you mention, I am aware of them. The Sontaran battleship isn't too bad; however the two or three other Doctor Who ship "models" that are there (if you can even call them that) are just plain awful and completely unusable.
