I have a polygon shapefile with 93 objects in it. They have a column with values for the buffer distance. 90 of these objects have 5 as a value, while the remaining 3 have 0.
When I use the buffer tool, the shapefile created leave out the 3 records containing the 0-values, so only a shapefile with 90 objects are in it.
Why is this? I have managed to do this before with 0-values, is there something I have forgotten?
