I am having a strange problem in ArcGIS Toolbox.

I am trying to use the Simplify Polygon (Cartography) tool from ArcToolbox. When I open the tool, there is no possibility to input Simplification Tolerance. Please see the attached image.

I can run the tool as a batch and from the Python window without any problem.

I am using ArcGIS 10(Editor) with Service Pack 5 on Windows 7 64Bit (English) and Windows Server 2008 64Bit (German). On both machines, I have the same problem. Any ideas?

I have reinstalled the software but the problem remains.


If you have installed Internet Explorer 11 (IE11), then be aware that there is a bug registered as NIM097058 - The 'Simplification Tolerance' option disappears from the Simplify Line and Simplify Polygon geoprocessing tools after installing Internet Explorer (IE) 11.

It's solved in 10.3. See bug description for workarounds in 10.2.


Even I faced same problem. Searched for help. Found this solution. Go to Search/ Simplify line/ Right click/Batch. There you will find option for "Simplification Tolerance"
