topic ce.selection does not seem treat all objects selected? in ArcGIS CityEngine Questions https://community.esri.com/t5/arcgis-cityengine-questions/ce-selection-does-not-seem-treat-all-objects/m-p/376441#M5200 <HTML><HEAD></HEAD><BODY><SPAN>The script I want to write simply changes an object attribute value for all selected objects but what I find is that it will do 1, I assume the first one it finds, and ignores all of the rest. The case is that I select a number of parcel polygons and run the script, only one has had the "Pop" attribute changed to the value I specify, i.e. 99, the rest of the polygons do not change.</SPAN><BR /><SPAN>The code is rather simple:</SPAN><BR /><PRE class="plain" name="code">ce = CE() thePop = 1000 print ce.selection() ce.setAttribute(ce.selection()[0], 'Pop', 99)</PRE><DIV style="display:none;"> </DIV><BR /><BR /><SPAN>The "print ce.selection()" line does return the proper number of objects but only one gets the Pop attribute modified.

No "() [0]" is required, this would limit the setAttribute function to the first item in the selection set, removing that it allowed the setAttribute to act on all objects in the selection.</SPAN></BODY></HTML> Fri, 06 Jun 2014 20:39:09 GMT https://community.esri.com/t5/arcgis-cityengine-questions/ce-selection-does-not-seem-treat-all-objects/m-p/376442#M5201 LoringTupper 2014-06-06T20:39:09Z
