Making room in Fusion 360 on cardboard

Reflection:

In this model, I found it is harder than using paper to make it as the cardboard is very hard to fold, moreover, when i was trying to use glue to hold parts together, it way harder than making it with paper, and the cardboard will slide and I have to hold them for a few second just to make sure the parts were held together by the glue, however, some parts fell apart and i have to re-stick them back. In the end, I use glue gun to hold parts together.
