[e]Yes, when you're building something larger than the nanofabrication bay of your nanofabber, you will have to have it fabbed in parts and assemble it by hand. [i]You can do this[/i] however.

...in fact, I believe you drew up more detailed house rules for doing exactly that, didn't you? ;)

In fact I did.

[h1]Nanofabrication[/h1] This is more a guideline than a rule, as the GM reserves the right to adjust times on particularly tricky nanofabrication jobs, but... If the device you are using to construct a given object can build it entirely within its nanofabrication chamber, then per Eclipse Phase page 285, it takes one hour per cost category. (1 hour for a Trivial object, up to 5 hours for an Expensive one.) If it is not large enough, however, it will take longer, as the device must be manufactured piece-by-piece and assembled by hand. Estimate the object’s volume (discount any empty space, such as cargo bay, crew cabin, or the space between armatures,) and divide by the volume of the nanofabrication bay you’re using. That’s how many construction cycles your nanofabricator will take to manufacture the object piece-by-piece. Divide the total cost by that sum, assign the result a cost category to determine how long it takes your nanofabricator to complete one construction cycle. Constructing the object once it’s been fabbed requires appropriate tools (which you damn well should have, if for no other reason than that you’re using a nanofabricator and can have any tools you needed trivially added to any given build cycle,) space (you will have to provide this yourself,) an appropriate Hardware skill (usually), and time, depending on the size and complexity of the object, which is a pure eye-ball. A rifle can be assembled in a few minutes by someone who knows what they’re doing and taking their time, while assembling a vehicle piece-by-piece by hand is likely to take months of work. Either way, once everything is fabbed in more than one part, it needs to be built to complete assembly. In objects which will require multiple build cycle, the character may declare they’re building while the nanofabricator is working; they will need to spend roughly all of their time attending to the fabber, but the upshot is that they’ll be ready to go shortly after the construction is complete. If not, then the GM will have to eyeball the construction time separately. The character should roll an appropriate Hardware skill after they have spent the time on final assembly. If they fail, then somewhere along the way they have screwed up (not necessarily during the final assembly,) and must take another reasonable period of time, about 16 hours for a large, heavy vehicle, to fix it. If they critically fail, then somewhere along the way they have screwed up royally and damaged components they installed beyond repair; they must remanufacture about 5% of the device and try again. [h2]Nanofabrication Example[/h2] You have a desktop CM, a gigantic scrapyard, black market blueprints for a Fenrir morph, and all the time in the world. The Fenrir has a credit cost of 100,000 credits. You guesstimate the Fenrir’s volume to be roughly the same as that of a Stryker IFV (ProTip: Guestimations can be done quickly by comparing to modern-day objects whose volume is known,); roughly 50 cubic meters. As with the Stryker, there is a significant amount of empty volume in that calculation; even with the legs folded up tight to the body, the Fenrir only occupies about 66% of the space of an area bounding it on all sides, so it works out as roughly 33 cubic meters. The desktop CM has a fabrication bay volume of 40 liters, or 0.04m3. 33m3 divided by 0.04m3 divides the job into 825 parts with a cost of 122 credits each; a Low cost. It takes 2 hours to manufacture 1/825th of the Fenrir with a standard Desktop CM; assuming non-stop supply of material input and power, a desktop CM can manufacture all the parts of a Fenrir morph in 1,650 hours, or just under 69 days. (You probably would have been better off spending start-up time using your desktop CM to build a larger nanofabrication device, with which you could have built a larger nanofabrication device, with which you could have built a nanofabrication facility.) The GM determines that this assembly is a monumental undertaking to do singlehandedly, but then, so is constructing a Fenrir morph piece-by-piece in a desktop CM. The GM rules that most of the construction has been taking place whilst pieces were produced by the nanofabber, and that it will take approximately 16 hours of work to complete the assembly. The character spends 16 hours working, and rolls their Hardware skill (Industrial, Groundcraft or Robotics would all be appropriate.) Disaster strikes, and they roll 99; a critical failure. They must remanufacture 5% of the Fenrir, because they bollocksed up the construction job somewhere along the way; they need to run off another 41 construction cycles, taking up 82 hours more, after which they spend another 16 hours and succeed on the roll, completing construction of one monster of a build project.
