Hi @pollacko, I added instructions: http://www.arcgis.com/home/item.html?id=54ad502f798c4cc780a1132ad44670a9 Most tools I made (especially those that are stand-alone like this one) follow the same basic principles: must be editing, the source features that are being processed must be selected and the layer in which the features are contained must be selected in the TOC. You must also select the the destination layer template by clicking it in the "Create Features" window. (This is what was referred to as the target layer in legacy ArcGIS versions.) These actions "tell" the Add-In where the features you want to buffer are and where they need to be stored. I tested the tool when writing the instructions and all worked well. (ArcGIS 10, SP4) not supported in any other version. Hi! I get the error "As a result of calls to the COM component has returned HRESULT E_FAIL error." Any idea what could cause that? Cheers jonas
