Just 'Add Field' (with their specifications) and then 'Calculate Value' for the column...</SPAN><BR /><BR /><SPAN>Like this:</SPAN><BR /><BR /><SPAN>[ATTACH=CONFIG]11133[/ATTACH]</SPAN><BR /><BR /><BR /><SPAN>The entire script is not that, this is a piece of that... Showing only this is a simple way to explain what is my problem:</SPAN><BR /><BR /><SPAN>Some shapefiles already have a column with the same 'Field Name' that i want to create...</SPAN><BR /><SPAN>When i run the script, ArcMap shows the </SPAN><SPAN style="text-decoration:underline;">'Warning 000012: Field already exists'</SPAN><SPAN> but the script keep going (this is good, it doesnt stop ever).</SPAN><BR /><SPAN>Then it runs the 'Calculate Value' in the pre-existing field and this is my problem...</SPAN><BR /><BR /><SPAN>I want to skip the 'Calculate Value' if the field already exists in the shapefile...</SPAN><BR /><SPAN>I want to create and set a 'default' value to the fields only in the shapefiles that doesnt have that field... And i have a thousands of shapes, so i cant do it one by one...</SPAN><BR /><BR /><BR /><SPAN>So, is there a way to put an 'if' in the model builder??&nbsp; Like " 'if warning 000012...' "</SPAN><BR /><SPAN>Or is there another way to solve this problem?</SPAN><BR /><BR /><SPAN>i need this...</SPAN><BR /><BR /><SPAN>thanks...</SPAN></BODY></HTML> Thu, 12 Jan 2012 15:15:14 GMT https://community.esri.com/t5/mapping-questions/interaction-help-in-modelbuilder/m-p/605497#M6560 Raphael_Augusto_FoscariniFerre 2012-01-12T15:15:14Z Re: Interaction Help in ModelBuilder https://community.esri.com/t5/mapping-questions/interaction-help-in-modelbuilder/m-p/605498#M6561 <HTML><HEAD></HEAD><BODY><SPAN>this is exactly what i was looking for:</SPAN><BR /><BR /><A href="http://resources.esri.com/help/9.3/arcgisdesktop/com/gp_toolref/automating_your_work_with_models/branching_colon_implementing_if_then_else_logic.htm">http://resources.esri.com/help/9.3/arcgisdesktop/com/gp_toolref/automating_your_work_with_models/branching_colon_implementing_if_then_else_logic.htm</A><BR /><BR /><SPAN>it creates a 'python script' with the 'if condition'... and it does it that exactly looking for a 'field name'...</SPAN><BR /><BR /><SPAN>impossible better!</SPAN></BODY></HTML> Fri, 13 Jan 2012 00:10:42 GMT https://community.esri.com/t5/mapping-questions/interaction-help-in-modelbuilder/m-p/605498#M6561 Raphael_Augusto_FoscariniFerre 2012-01-13T00:10:42Z
