Island Detection: Find Floating Letters & Lost Pieces

An island is any closed region of material that's surrounded by cut paths on all sides. Without a bridge, an island has nothing holding it to the rest of the piece — it falls onto the cutting mat. Lazrit's island detection finds every one of them, including the ones you can't see at a glance.

The problem

Manual island review in Illustrator means clicking through every nested path and asking 'will this fall out?'. Lazrit does it in milliseconds with no false negatives.

How Lazrit handles it

  1. Path tree walkLazrit parses the SVG path tree and identifies every closed region. Nested-path winding rules are respected.
  2. Connectivity graphEach region is added to a connectivity graph. Regions that share a path with the main piece are connected; orphans are islands.
  3. Surface resultsIslands are listed in the workspace with a count. Hover an island in the list to highlight it on the canvas.

Frequently asked questions

Does island detection handle compound paths?

Yes. Compound paths (multiple subpaths in one SVG element) are decomposed and re-classified.

What about overlapping paths from a sloppy trace?

The tracer cleans up overlapping paths before topology runs. If something still looks wrong, the workspace lets you edit the trace.

Will Lazrit detect islands that I want to keep separate?

Yes — every island is a warning, not an error. You can choose to keep an island unbridged and accept that it'll fall out.

Can I exclude a region from detection?

Mark the region as engrave-layer; engrave paths are exempt from island detection because they don't cut through.
