Topology Validation: Detect Loose Islands Before You Cut

Topology is the relationship between every cut path in your file. A 'good' topology means every piece you want to keep is connected to the rest of the design. Lazrit's topology engine inspects the geometry, classifies every component, and produces a list of warnings before you export — no more burning material to discover a fragile feature.

The problem

Most laser-cut failures aren't a settings problem — they're a topology problem. Floating islands, hairline webs, and unbridged counters look fine in Illustrator and fall apart on the bed. Lazrit catches them at export time, not after.

How Lazrit handles it

  1. Path classificationEach closed path is tagged as outer boundary, hole, or island. Outer boundaries define the main piece; holes are subtractions; islands are everything else.
  2. Web-width measurementFor every pair of adjacent paths, the algorithm computes the minimum distance between them. If that distance falls below the material's minimum-detail threshold, you get a warning.
  3. Island bridge proposalEvery island gets evaluated for the shortest valid bridge to the main piece. Bridges are surfaced as proposals you can accept or edit.
  4. Visual overlayThe workspace renders flagged areas in a warning color. Hover for the exact measurement and recommendation.

Frequently asked questions

Can I disable topology checks for one export?

Yes — accept all warnings before exporting. The warnings count goes with the export log so you can audit later.

What counts as a 'thin web'?

Any gap between two paths smaller than the material's minimum-detail threshold. Default is 1 mm for wood, 0.4 mm for mylar.

Does the topology check work on engrave layers?

Topology applies to cut paths. Engrave-layer paths don't separate material so they're exempt.

Is the topology check deterministic?

Yes. Same input, same warnings. No AI, no randomness — straight geometry.
