Hello Colin, Do you have small regions in your data that, when negative buffered, will yield a null object? i.e. the objects have "collapsed" to nothing.

To do this I need to create a buffer with a negative value, when I use the buffer tool in MapInfo and enter a negative value all works as expected. However, when I try to recreate this in MapBasic I get a warning message saying: "Warning: Operation did not produce a result. No errors detected" Any ideas as to why I can not create a negative buffer in code? All help appreciated, will sum.
