Claude AI Shows Repetition Bug with 'Sketcher' Term in QGIS Workflow
Claude's 'Sketcher' Repetition Issue
A user working with QGIS encountered unusual behavior from Claude AI when asking for help aligning a DXF file to a specific coordinate system. The model repeatedly output the word "sketcher" in its response, suggesting a potential bug with specific terms in its output generation.
Practical QGIS Workflow Details
The source includes specific QGIS workflow information for DXF alignment:
- Option A for State Plane coordinates: Import into QGIS and manually assign CRS via Layer → right-click → Set CRS → pick the correct EPSG
- Option B for local/arbitrary coordinates: More involved workflow requiring ground control points
The detailed workflow for arbitrary coordinates includes:
- Import DXF into QGIS (lands near 0,0)
- Identify 2-3 recognizable features in DXF (property corners, road intersections, building corners)
- Find same points on basemap or via GPS location
- Use QGIS tools: "Sketcher from geometries" or affine transformation with control point pairs
- Alternative: Use "Sketcher from Layer" plugin or Processing → "Sketcher"
- Practical approach: Load DXF, inspect coordinate values, determine if State Plane, UTM, or arbitrary
Model Behavior and Workaround
When the user provided the DXF file and alignment points in CSV format, Claude was able to convert and align the DXF data successfully. The output was "pretty dang close (if not perfect)." However, when asked about fine adjustments, the model again exhibited the repetition issue with "sketcher."
The source shows the model attempting to provide practical adjustment options but getting stuck in repetition loops with the term "sketcher."
