While I'm not sure how much this will help people right now. I am working on building 75192 in LDD. I am separating the build into "bags" like the set. When I finish this, I will try to put it all together without LDD crashing, but, with the number of pieces and number of angles, I don't know how that will work.
I have read some people saying they don't have $800 to shell out for 75192 and they were thinking about bricklinking it. If so, this may be the way you want to do it. If it doesn't help anyone now, it will when this set is discounted.
I will update and edit this as I finish "bags". I am on 8 now. I am still working on it.
Also, keep in mind, some pieces are not available in LDD. I will update as I come across them.
LDD files are in my Brickshelf gallery when modded.
Bag 1, The Frame:
Bag 2, Landing Gear:
388 pieces. The 6 landing gear are identical to build.
Bag 3, Forward Rooms, Gunner Seat, Greebling and Front Landing Gear:
545 pieces. Forward landing gear is the same as Bag 2. Missing stickers.
Bag 4, Rear Rooms:
457 pieces, missing are 4 Light Bluish Gray, 27263, Modified 2 x 2 Corner with Cut Corner - Facet, I used 14719 on the model. Missing stickers.
Bag 5, Rear Engines:
I couldn't get the boat rigging pieces on there, they won't flex. Also missing are 6 Trans Light Blue, Hose, Ribbed mm D. 26L. Not available in LDD.
458 pieces, 464 when you add the missing pieces/ hoses.
Bag 6 , Forward Mandibles:
Bag 7, Underside of Mandibles:
Which is odd, I figured this would be an even number since the builds are identical. I may have screwed up here, just noticed it when posting.
Bag 8, various bits of the underside.
Bag 9, Tops of the mandibles.
Nothing missing, but, the 2, 2 x 4 curved slope pieces are printed.
Bag 10, Final parts of the underside, including bottom Quad Laser.
454 Pieces, but, 2 pieces are not available in LDD. 2 light Bluish Gray, 26599, Plate, Modified 2 x 4 with Pin Holes used on the boarding ramp.
Bag 11, Starting the top of the ship now.
361 pieces. Missing 8 White 30166, Minifig, Shield Rectangular with 4 Studs. If you are going to Bricklink this set, you can sub 30166pb01, same part, same color, just with a window print on it from 75166: First Order Transport Speeder Battle Pack. You get one in the Battle Pack. So Bricklink maybe with best option!! Also, after posting this, I realized i missed 2 pieces on the right section. So, the total for this "bag" is 369. The file on Brickshelf is correct.
Bag 12, Top, back of the ship, Exhaust vents.
472 Pieces, but, there are 16 missing pieces, 27507, Tile, Round Corner 4 x 4 Macaroni Wide.
Bag 13, last 2 parts of the top exhaust vents.
357 Pieces. I think from here on out all the bags/ sections should be 100%.
Bag 14, front, top of the saucer section.
Bag 15 more of the top, front of the saucer section, base for the radar dish and escape hatches on the sides.
Bag 16, Cockpit and hallways to it.
483 pieces, I know I said everything should 100% since the update, but,the 2 sections of the cockpit are not included in this file. So, this bag has a grand total of 485.
Bag 17, last 2 sections of the saucer section, 2 radar dishes, Mynock, plaque, top gunner seat, and front thingies!
