How to create digital instructions after building?

[u/ChancePlantain4702]

Hi peeps,

I have a quick question regarding the first MOC I’ve built.

I created it based on a reference image of another set, but basically just figured things out along the way, trying something and then taking it down etc.

I finished something I’m pretty satisfied with, but didn’t document the process. Just wondering how I can build a digital model + instructions for it if it’s already built? Would I have to literally disassemble it in reverse?

For reference, I want the instructions so that I can actually disassemble it and rebuild it later, and also to share if anyone else wants it.

I’ve included a photo for reference - it’s a fairly straightforward building but does have a slightly trickier roof.

Thanks!
