Can I retrieve files? I made 3 1/2 years ago when I canceled the subscription

I have Tesla Giga Plant In Texas interested in my hydrogen, combustion engine design, and I no longer have the file on my iPad. I’m wondering if I reactivate the subscription I once had, Will it include the engine design file I had with it? It took me a year to design that engine, and I am not sure I can do it again. I desperately need to retrieve that engine design file on Shapr 3-D that I once had. Need help
