RAMTT icons
Each icon has a filled version, made from its line instead of by hand.
What it is
The filled versions are made from the line set, the way SF Symbols and Heroicons make theirs. Each closed shape is filled with its outline added, a shape inside another becomes a gap, and an open stroke inside a shape is cut out of it.
The parts
Filled from its line
The filled icon has the outline of the line icon: the same corners, the same holes and the same cuts.
Merged into a single set
Each pair shows the package’s icon beside the one in the set now.
The ground on sport and fuel
In a list of sessions or meals, the fill sets them apart from the buttons and arrows beside them.
