That's exactly what I've been thinking about after having seen the video ( link on another thread ) of the virginia class...I guess it could be easier to a certain degree to do a model just like in real life, sections, complete built in interior quarters, etc...But I wouldn't know, apart from that miserably failed Skipjack, this is my first ever 3d model

.
Ps. But if one considers all the interior tubes, cables, everything to match when putting together the final model...well...it depends on the level of detail and quality one desires I guess...
