Technical Notes
- SVG import interprets all vector path data including lines, arcs, Bézier curves, and polygons
- Bézier curves are approximated to polylines during import
- DPI setting affects the coordinate scaling — choose the DPI matching your source application
- SVG export produces clean vector output suitable for web browsers and vector editors
