Hello
I am using QGIS 1.7 in a Windows 7 environment. Everything seems great except for the simplify function (Vector->Geometry Tools->Simplify Geometries) I am trying to simplify an ESRI shape file which is around 95M. I have tried various tolerance settings, but although it looks like some simplification is taking place, actually the file is unchanged. So for example with tolerance setting of 1.0 I get an encouraging message that says: 'There were 3638321 vertices in original dataset which were reduced to 559351 vertices after simplification' However after saving the changes to the layer, the dataset still looks identical to the un-simplified version and the file size remains unchanged at 95M. I have tried to simplify smaller shape files also, but with the same result. Can someone tell me what I am I doing wrong? Chris
