Review unused content before removing it

Purge unused families and types

Why it matters. Purge Unused is a dialog that does not tell you what it will take until it has. Line patterns and subcategories are easy to guess wrong.

What VI MCP does. Run the check, read the report, confirm. Line patterns, subcategories and arrowheads are refused rather than guessed — a wrong guess deletes a line style every drawing uses.
