Review this precheck with your fabricator. Complex apertures, regions, arcs and other unsupported constructs are identified in the report.
Formula and worked example
Method. The precheck parses supported Gerber and Excellon geometry and compares trace, drill, spacing and other supported dimensions against editable limits.
Assumptions. Upload a ZIP or individual files and confirm the layer mapping. Unsupported geometry and unresolved files are marked Not checked.
Example. A parsed 0.12 mm straight trace is flagged when the entered minimum is 0.15 mm.
