Supported subset & limits
Basic paths (including curves), rectangles, circles, ellipses, polygons, lines and polylines. Filled shapes preserve supported fill rules and holes; strokes become filled polygons. Transforms apply to geometry. Uniformly transformed strokes are supported; nonuniform or skewed strokes are skipped with a warning. Curves are flattened with a bounded physical tolerance.
Scripts, event handlers, references, CSS, masks, filters, images, foreign objects, text/fonts, nested SVG viewports and external resources are not converted. Export text as outlines first. Unsupported content is reported; review this rebuilt preview. No original SVG markup is inserted into the page.
This exports the union of supported polygon fills, with holes. Colors, layers and print roles are not retained. SHP2STL adds its ordinary base and inward perimeter walls. This is a best-effort converter, not an SVG editor.
