Hi Bob
This is utterly brilliant! To do the Double Down room is truly awesome 
As a matter of interest, are you using the same technique / formula for designing / drawing this as you would with a CAD for 3D printing?
And "copying" /replicating glass, and shiny metal - as well as windows, table tops etc, there was a huge amount on board QE2....thinking of the doors with lovely handles and the round portholes on the swing doors onto the outside decking - Is this tricky?
Thanks Rosie! To answer your question about the technique, its pretty much the same. The software I am using, Sketchup, is not a full CAD software but it can save files in formats that CAD software uses. I have been toying with the idea of finding someone with a more sophisticated software and see what the file would look like opened in it.
On your second question about certain features being tricky, the answer is yes and no. It is tricky to get the right glass tint, metal surface and other finishes as Sketchup is a bit limited in its selections. I'm learning how to get better at this through a material editing feature though.
It is not tricky from the standpoint of being able to reproduce the geometry of an object. It's been very easy for most of the 2D, horizontal measurements given the deck plans and general arrangement plans I have. However, for the vertical measurements, such as doors and deck heights and the sizes of portholes, tables and furniture; I have to rely on photos and videos that capture the objects and scaling them to the estimated heights of various nearby objects but mostly people and their body parts (knees, hips, arm lengths, etc.). For example, the Double Room chairs took about 4 or 5 attempts. I "guesstimated" the chair height and width using the sitting knee height and shoulder widths of people in the chairs from family photos and advertisements and then placed it in the room to see if it all fit in context. Even now, looking at it a day later, I may scale it down about another 3-5% - thank God for the scaling tool where I can reduce or expand complex objects with a few mouse clicks!
All good fun and a great hobby for me
