Hello Tony, The MapInfo environment is naturally disadvantaged when it comes to node thinning as there is no built-in support for topology. Without it, tools can often be thrown by the simplest of topological differences between two adjoining regions (e.g. an extra node). I ended up writing my own which needs a layer of "hints" about where regions node join and split. It's not a very good general solution but did work for my application.
I have not tried it but I'm told that Safe Software's FME (the big brother of the Universal Translator) has a good thinning algorithm. I think they still run a free trial of FME so that may be worth a look.

Hi MapInfo Listers I have been trying to "thin" (simplify) a MapInfo table of complex abutting region objects using the MapInfo Professional "Snap/Thin" tool. The result leaves numerous gaps/overlaps in the created regions and is therefore an unsatisfactory result. Short of redrawing the boundary files manually (painstakingly either by removing nodes or tracing with reduced complexity), I was wondering if there is a tool (preferably free) out there that may be known to someone which will achieve the desired result (reduced complexity, therefore reduced file size) without the MI Pro result of gaps/overlaps. I have searched the "Tools" area on DirectionsMag without any success. Thanks in advance for any assistance.
