Coordinate points are used for what purpose?

• A. To measure distances on a single sheet
• B. To indicate scale on drawings
• C. To locate the same point on different sheets
• D. To label components

Answer: (C)

The main idea is using coordinate points to locate the same point on different sheets. When drawings span multiple pages, coordinate points act as a shared reference that ties a specific location to every view. This lets you transfer exact positions, check alignment, and ensure consistency across sheets, which is crucial for matching features like holes, bends, or edges in the same part when viewed from different angles or on separate sheets.

This approach is different from measuring distances on a single sheet, which is about dimensions within one view; it’s different from indicating scale, which uses a ratio or bar to represent size on the drawing; and it isn’t primarily about labeling components, which uses tags or callouts. By establishing coordinate points, you can quickly locate and verify the same point across all drawings, improving accuracy and efficiency in multi-sheet layouts.
