What this does
Slicers like Bambu Studio, Orca, and PrusaSlicer only read plain, inline SVG geometry.
Files exported from Adobe Animate / Flash (and some other tools) hide every shape inside
<defs> and draw it with <use> references — so the
import comes up empty even though the file looks fine in a browser.
This tool rewrites the file as one plain <path>:
<use>/<defs> resolved, transforms baked into the
coordinates, curves flattened to fine line segments (way below printing resolution), and
open paths sealed. Size is preserved at 96 dpi — 1:1 with Illustrator exports.
Everything runs in your browser; the file never leaves your machine.
Want a rounded 3D solid instead of a 2D outline? Roundover extrudes the same SVG straight to an STL.
