Using solidworks to verify wing egress from basement

[wmax351]

I've got a basement i'm planning to turn into a workshop for a fly baby. I do want to confirm that I will be able to remove the plane without needing to build egress windows through the foundation.

The basement has a staircase in the middle, dividing between a finished and unfinished half.

There are non-bearing walls on the side of the staircase, which I plan to knock down one or both as needed when the wings are complete. If needed, I can remove the stairs as well.

I'd build a mockup, but then I'd need to knock down the walls, and put them back up, to knock them down again.

So I build a mock up in solidworks. https://1drv.ms/u/s!An4agHH7T0TFiPIn4MIuLGiXCG9kRQ

The model has a rough version of the wing, and the basement set up with the walls removed. Once its through the stairs, it's a straight shot.

Anyone want to give it a go? I never got good at the motion control features.
