[Qgis-user] Centroid error

[Pat Brown]

Hi List,
I have a layer of around 17000 polygons, for which I want to derive the
centroid. Using the Vector/Geometry Tools/Polygon Centroid tool the process
progressed to around 45% when this message came up: "Error processing
specified tolerance. Please choose larger tolerance". Can anybody tell me
why this occurred and how does one set a larger tolerance?

Thanks,

Paddy
