Creo Drawing Line Width and Pen Number Mapping: Pre-Batch Output Checklist

Three types of mapping relationships

• 1Layer / Entity Properties → Creo Internal Line Width (determined by the table file and layer settings).
• 2Creo Line Width → Output Pen Number or PDF Line Width (determined by the pen table or print configuration).
• 3Output pen width → Physical pen width or raster line width (determined by the device driver).

Pre-batch output checklist

• Confirm that all drawings in the batch use the same table file to prevent mixing different project templates.
• Randomly check 3 drawings with varying sheet sizes to verify that the line widths of hatching, centerlines, and hidden lines comply with corporate drafting standards.
• PLT output: verify that the pen configuration matches the actual plotter pens. PDF output: ensure line widths are defined in millimeters, not pixels.
• Check for line width history configurations mapped by color, as converting to black-and-white output may reduce distinguishability.
• For drawings with Chinese annotations, verify font embedding or substitution rules to prevent square boxes in the PDF.

Move the check to batch pre-validation.

Manually verifying the above checklist is nearly impossible to sustain for batches exceeding 50 items. A more viable approach is to automate determinable checks (table file consistency, missing line width mappings, and missing fonts) in batch pre-inspection, while reserving engineering judgment-based items (compliance with drafting standards) for sampling.

The value of pre-checks lies not in finding issues, but in catching them before resources are consumed.
