Drafting-Sheet Coverage

Audit drafting-sheet title-block and legend coverage.

Description

Drafting sheets use title blocks and legends to make drawings interpretable.

Drafting sheets use title blocks and legends to make drawings interpretable. An element checklist can reveal missing labels while technical drawing review remains separate.^[1]

When to use Drafting-Sheet Coverage

Use this tool to audit drafting-sheet title-block and legend coverage.

Prepare production measurements or checklist records for one planning period. Confirm units, staffing assumptions and caller-selected criteria before running the calculation.

How to use Drafting-Sheet Coverage and understand its results

Prepare production measurements or checklist records for one planning period. Confirm units, staffing assumptions and caller-selected criteria before running the calculation.
Enter requiredElements, presentElements using the field table and calculation rules, then run the tool.
Read coveragePercent, matched, missing, unexpected. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
requiredElements	Required drafting-sheet elements	list of string	Required
presentElements	Present elements	list of string	Required

Enter requiredElements and presentElements label lists. Trim labels, reject blank entries and match case-insensitively with en-US lowercase. Deduplicate each list, requiring at least one distinct required item; an empty observed list is allowed. Return matched, missing, unexpected labels and coverage. Duplicate normalized labels keep their last trimmed spelling at the first key position.

coverage%=100 matchedDistinctRequirements/distinctRequirements

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
coveragePercent	Coverage (%)	number; minimum: 0; maximum: 100
matched	Matched items	list of string
missing	Missing items	list of string
unexpected	Unexpected items	list of string

Limitations and assumptions

The drawing, dimensions, symbols and correctness of the listed information are not inspected. Spelling differences beyond case and outer whitespace remain distinct.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
