This is the basic requirement of the wooden door frame:
The requirement is to make sure that the door frame does not skew or deform.
- What's the minimum number of wooden pieces to be added inside the frame, so that the frame of the door remains solid, and doesn't deform?
- What's the principled approach to handle this? Because currently I mostly use eyeballing and intuitive thinking.
1. My guesses so far
1.1. Extend from corners at 45 degrees
1.2. Extend from corners to opposite, regardless of degree
No angular pieces at all. What's wrong? Am I missing something? Or are the engineers missing something?
