Well structured information on building pans is scarce, especially due to the rise of chinese manufacturers mass-offloading garbage instruments onto the market in recent years, and community-trusted manufacturers taking down information previously public, due to incidents information being stolen or misused in by said garbage producers, as far as I know of.

I marked the note fields on the surface and went on to pre-shaping.
