Creo Line Weight and Pen Mapping: Pre-flight Checklist for Batch Output

Three mapping relationships

• 1Layer / entity property → internal Creo lineweight (controlled by table files and layer settings).
• 2Creo lineweight → output pen number or PDF lineweight (controlled by pen tables or print configuration).
• 3Output pen → physical pen width or raster line weight on the plotter (driven by the device driver).

Pre-flight checklist for batch output

• Ensure all sheets in the batch use the same table files; do not mix project templates.
• Spot-check three sheets of different formats for hatching, centerline, and hidden-line weights against your drafting standard.
• For PLT output, verify that the pen table matches the physically loaded pens; for PDF output, ensure lineweights are defined in millimeters, not pixels.
• Check for legacy color-to-lineweight mappings that lose distinction when converting to monochrome.
• For sheets with Chinese annotations, verify font embedding or substitution rules to prevent boxed glyphs in the PDF.

Shifting checks to batch precheck

If this checklist depends on manual per-sheet review, it cannot be consistently executed beyond 50 sheets. A better approach is to move automatically checkable items (table file consistency, missing lineweight mapping, missing fonts) into batch pre-checks and reserve judgment-based items (drafting standard compliance) for spot checks.

Precheck identifies issues before media consumption, not after.
