What actually changes.
Vector Boy builds a closed outer boundary for every connected black area. White counters remain separate cut-outs. That is the difference between a filled shape and a loose collection of strokes.
Before export I inspect three things: narrow bridges, tiny islands and counters that are close to collapsing. Geometry can be closed and still be too delicate for the tool or material at the intended size.
Check before the machine
- The outside boundary forms one complete shape
- Counters in letters such as a, e and o remain open
- No duplicate contour sits directly on another
- Small islands are intentional and practical at output size
Step by step.
- Use Result view to confirm that the black area is connected.
- Switch to Vector and zoom into tight corners.
- Remove unintended islands with the lasso.
- Increase Bézier simplification only while the form remains stable.
- Export SVG or DXF and inspect it again in the destination software.
- Make a test at the actual size before producing a batch.
Closed means geometrically valid, not automatically manufacturable. Minimum bridges, tool width and material behaviour depend on the machine and output size.
Questions before export.
Why do cutting plotters need closed paths?
A closed contour describes a complete cut shape. Open ends can create gaps or unexpected travel.
Are counters closed as well?
Yes. Cut-outs are stored as closed counter-contours inside the black form.
Can Vector Boy reveal duplicate lines?
Vector view shows the generated contours. The final production check should also happen in the destination software.
