Topology Error Creator & Fixer QGIS 4 compatibility
QGIS 4 ready Active
Yes — Topology Error Creator & Fixer supports QGIS 4 (declared max version 4.99.0).
Safely detect, create and repair vector topology errors including invalid geometries, duplicates, polygon overlaps/gaps, and line overshoot/undershoot.
About
Topology Error Creator & Fixer provides controlled topology-error creation for training/QA plus automatic preprocessing that detects common topology problems and selects suitable repairs. Version 2.2.3 hardens exception handling for QGIS Plugin Repository security scanning by removing silent try/except pass/continue patterns and replacing the Bandit-flagged standard pseudo-random generator, while retaining Safe Processing mode for dense village/cadastral polygon layers. Supports single files and folders with Shapefile, GeoPackage and GeoJSON. Uses qgis.PyQt for QGIS 3.22 through QGIS 4.x compatibility.
