Frequently asked question

Why is my model broken after I install 9.0 Service Pack 1?


This article pertains to ArcGIS versions 9.x. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools.

At ArcGIS 9.0 Service Pack 1, Dissolve had a 'Multipart' parameter added. Check if the model contains the Dissolve tool. If it does, the issue may have been caused by a change to Dissolve's signature.
