Just to give you a sense of how far I'll go . . .
1. Take
this quasi-accurate model of the Kumari.
2. Research the file format of Bridge Commander models, since they're not simple LightWave LWOs like Klingon Academy used to use.
3. Discover that BC uses some delightfully-open-source format you've never heard of before. ("What the hell's a .nif?") Discover also that you have to install two different things to make Blender import them, but they're available.
4. Load up the Kumari in Blender, cursing its standards non-compliant user interface. Export it to .3ds.
5. Load up the Kumari in SketchUp. Be unsatisfied with it.
6. Go try to find Klingon Academy mods, only to discover that the main storehouse site is dead because some jackass hacked something supposedly damaging files and the slacker running it just shut it down.
7. Persist and find them anyway, thanks in part to
this TrekBBS thread.
8. Get the Kumari from
here.
9. Import the .LWOs (since for some reason there are several) to Blender.
10. Export the .3ds.
11. Import the .3ds to SketchUp.
11a. Change camera view so you can move it to the right spot in the field.
11b. Change to the dimension tool so you can have a measurement of the ship alongside it.
11c. Change to the rescaling tool to get it to 360 meters, because there's not a single 3D modeler who ever seems to put models to scale. It's some cultural thing I don't understand.
11d. Change the camera view because it doesn't work right in parallel (orthographic) view.
11e. Rescale it to close to the right size, because SketchUp is imprecise in this regard. Then sit there typing in numbers to get it closer.
11f. Save that thing so you don't have to do it again.
12. Discover that the volume calculator can't operate on it correctly for some reason (i.e. at 360m it only reads the same volume as a Constitution, which isn't right at all . . . the Connie is long slender lines and flat saucer, the Kumari's a big fat school bus by comparison). This probably has something to do with the multiple different .lwo files.
13. Screw around with the model trying to get it to work. Fail.
14. Recalling a superior BC Kumari
here, go get it.
15. Start cussin', because instead of the .nif file format you've gone to all the trouble to be able to load, this is a .bcmod file. What the hell is that?
16. Find the Bridge Commander Universal Tool
here.
17. Figure out how to use its standards non-compliant user interface.
18. Get it to unpack the .bcmod file so you can then steal the .nif file out of it.
19. Go find the damn .nif that's in some weird ass location and move it to where your other mods and ship models and whatnot are all in a semi-organized mess foolishly located 15 layers deep on one of your drives.
20. Open the Kumari in Blender, cursing its non-compliance.
21. Export the Kumari as a .3ds to the place where you've been putting all the exports. Chide yourself because you know that you'll never remember what came from where, and so even if you do ever get around to putting all these ships in SketchUp's 3D Warehouse like you've been thinking of, there's no way in hell you'll be able to credit all the right people.
22. In SketchUp, import the Kumari. Follow the steps from 11a-11f.
23. Run the volume calculator.
24. Cuss because the damn thing didn't even report a volume as large as a Constitution Class, meaning the model's boned somewhere.
25. Fiddle with it to try to make it work. Fail.
26. Go back to the inaccurate Kumari and say tohellwifit, run the volume, and get a decent-looking figure anyway.
27. Cuss.
28. Copy the Kumari and paste it alongside a Constitution. Compare the hull dimensions, ponder how many of such-and-such part can fit into such-and-such other part, and so on. Accept the 592,291 as being pretty close comparing the two models you're looking at.
29. Then double-check against the orthographic views of the Kumari at Drex Files, realizing that the big fat ship you're looking at only has the most passing of resemblances to that graceful bird.
30. Overlay the SketchUp window in semi-transparency and try to stretch and skew the inaccurate BC ship to fit as closely as possible, then rescale it again.
31. Run volume again.
32. Get 314080 cubic meters.
33. Gun-shy now, copy this revised model and paste it alongside a Constitution in SketchUp. Compare the volumes of different pieces in your mind.
34. Decide it looks okay, and call it a good day.
It's within a respectable margin of error, so if you don't like it, you can kiss my ass. (And I say that with love.)
