Attached if the long method of Calculate Field.&nbsp; &nbsp;Thank you in advance.</P></BODY></HTML> Thu, 17 Jan 2019 19:57:26 GMT RichardTruong 2019-01-17T19:57:26Z Model Builder https://community.esri.com/t5/modelbuilder-questions/model-builder/m-p/794576#M1431 <HTML><HEAD></HEAD><BODY><P>Is there a simple method in ModelBuilder to populate/field calculate several different fields from other different fields all resided in a same feature class.&nbsp; For example, I would like to field calculate from field call F1 to F1A, from F2 to F2A, from F3 to F3A and so on so forth.&nbsp; &nbsp;All fields format are exactly identical, exception to the name of the fields.&nbsp; From ModelBuilder I use the 'Calculate Field', unfortunately, there are over 200 fields for this feature class, and using Calculate Field option for each field can take forever to setup.&nbsp; &nbsp;Is/are there any simple options from ModelBuilder to create for this type of repetitive task?

I realize this is a little advanced but I think it's the best approach.</P></BODY></HTML> Fri, 18 Jan 2019 23:19:53 GMT https://community.esri.com/t5/modelbuilder-questions/model-builder/m-p/794577#M1432 curtvprice 2019-01-18T23:19:53Z
