I have begun designing a 3-D computer model of Cats' Lair, based on the series' production material. The project is coming together well enough so far, though there are parts where the interior seems a bit hard to cram into the outer shape. I've referenced the floor plans and section view that I found here and on other sites, but I wonder if I might be working with obsolete designs. My skill is not in free-form design, so all of the curvy and artistic bits will have to wait. (The closest I've come to that is a reasonably accurate interior for the council room, but then I got tripped up with the sconces.) Much of the scaling of my model comes from specific measurements listed in the production drawings, such as the Lair's height and comparisons of Lion-O standing next to certain doors. What I'm finding out, though, is that the grand scope of some of the illustrations would make a few of the rooms too big for their supposed locations. One particular problem I've run into is the sword chamber. I've been going by the drawing that has the pylons along the walls, which, when considering the detail drawing of Lion-O with the doorway, would make the room far taller than the side-view section drawings show. Perhaps I've conflated the sword chamber in the Lair with that on the ship, in which case I should go watch the show again for clarification. Another difficulty that is starting to present itself is the upper floor. Whereas the control room has space to extend into the "neck" of the Lair, and the bunk rooms have at least the curve of the "shoulder", the guest rooms toward the rear are going to be flattened practically into non-existence by the slope of the "back" in that area. This was probably just a case of the artist doing quick sketches without thinking much about 3-D viability, though it's possible I'm working from obsolete sources. I've seen some other Cats' Lair projects on here, but none seem to be taking the approach of making an all-inclusive design. Advice, clues, or further source material would be appreciated; and I am open to collaboration. For updates on this and my various other projects, visit my Gab account.
