Cabin looks awesome, and so does cockpit... Can't wait to see the final product! (Take your time though, I know it's done when it is) One quick question- how detailed are you planning on making the avionics- systems, checklists on mfd, custom maps with navigraph, sids&stars navigraph support? Or just basic gps and displays? I would prefer more detail but understand that it is freeware. Either way, it is going to be AWESOME!
The systems are going to be as advanced as I can make them, but keep in mind that this will be my first time programming
anything, so that really isn't saying much as of now. But believe me, I will try my best to model these systems better than the default planes. It will just take some time. If I can get a coder who is willing to waste some time developing freeware, then an FMC is a possibility.
Maybe one day you could also do the original CL600 with an analogue cockpit. That would be amazing.
Thought about it...Right now I am regretting my original plan of simulating the 604 and 601 just by the sheer amount of work required. I agree, the steam gauges are awfully cool in "older" jets.

From what I've gathered, the 601 had the same cockpit as the original CL600, and has a plethora of digital configurations as well.
So one day releasing the older variants is not totally out of the question. It just comes down to whether or not I feel like doing it after this project is finished.
Speaking of the current project, here is a progress update: The interior and exterior are both at roughly the same stage of completion. Modeling is probably around 75% done, leaving the landing gear, crew seats, yokes, and other finicky little parts all over the plane to finish. I tried my best to get comprehensive shots of the interior, albeit the small scale makes it really tough to avoid mesh disappearing when zooming in, especially with a wide FOV.
Lavatory still needs some work...
