I think I am nearing completion. For now.
I plan to work on a Locknar next, followed by an Excelsior.
Then I may revisit this ship with much more experience under my belt.
Someday, I certainly will have a much more detailed deck-by-deck ship, ideally one that could be used for rendering scenes (inside and out). That is beyond my abilities with this software at this time.
The Locknar design I work up next will be used by a Role Playing group, so I expect to learn a great deal more about theoretical functional use from that design (and also much more detail in that design).
Sorry I've not been making progress in the last week - we had windows replaced, significant home IT changeover, and a major snow storm (that wasn't supposed to be), so I didn't get to work on this as much as I had hoped. We are due for more snow this week/weekend, and nothing significant on my schedule, so I should be able to actually GET somewhere with it again soon.
