When is 'schematic' be used as a noun?

[Torsten]

Hi,

When do we use the word 'schematic' as a noun? I've seen several web pages where 'schematic' is used meaning 'portfolio/catalog'. Is this common or would you say that 'schematic' should primarily be used as an adjective?

Thanks,
Torsten

Schematic is short for "schematic diagram". Now we just use the adjective on its own as a noun, mainly for electrical diagrams.

I would find it distinctly weird to see a catalogue referred to as a "schematic".
