unit()

Declares the length unit of the file it is written in. Numbers in the file are then in that unit; the default is millimetres. Must be the first statement after the imports (top level, before any geometry, once per file, literal string) and is only allowed in part files — assemblies use the project unit from fluidcad.json.
