Feature 2 should according to DIN EN ISO 1302 describe the [transfer characteristic]. (don't know if this word exists in englisch, but ist what it means in German... Maybe its just "transmission band")
Basically you tell the Quality ensurance - guy what machine-settings he has to use to measure the roughness of the part, by filtering out the "waviness".
the Pt 100 should be the profile-height, although I thought that PtMax is used for this.
Feature one is weird.
It could mean that the surface pattern is crossed. But then the dots aren' needed.
If you can, ask the guy (/girl :D) what he meant.
(....and to relax with the complexity of his drawings.
I usually don't use this kind complex annotations to avoid misunderstanding, and confusion.)
