island tool · one purpose
design in.
stencil out.
Isla finds the floating islands in your artwork and adds the tiniest possible bridges to hold them in place. Design stays untouched. Cut file exports as SVG or DXF.
got a stencil already with islands + bridges drawn in? just need it turned into a clean vector? use convert mode — it skips bridge detection and just traces your file.
one job
Drop a black line drawing. Isla detects every enclosed shape, adds the tiniest bridges needed so nothing falls out, and gives you back a hairline vector your cutter can follow.
lower = picks up fainter/thinner lines. higher = only the boldest darks. regenerate after changing.
runs 100% in your browser. no upload, no server. svg for the web, dxf for cad/cutter software.
how it works
detect islands
we scan every enclosed piece of your design that would fall out of a real stencil.
pick the minimum
for each island, we shoot rays and find the shortest gap back to the mainland.
bridge, don't redraw
the design isn't retraced or smoothed. we only add tiny ties.
