I want to create a model in ModelBuilder that contain two processes:

  • The first process is to select a feature using an expression.
  • The second process is to delete the feature selected in first process.

I want to do both processes within the same feature Class, so I cannot use the Select (Analysis) tool because that gives me a new feature class as output.

I am using ArcGIS 10.2 for Desktop.

I found the Select Layer By Attributes tool but it does not accept feature class format, and I do not have any other format except feature class.

If the model is outside of ArcMap you will first have to use Make Feature Layer tool, then you may use Select Layer by Attribute tool followed by the Delete Features tool.

  • thank you man .. but I can't convert Feature Class to Feature layer because I want to use the Same feature Class many time .. – Nasser AlHinai Dec 2 '14 at 13:07

    I'm not sure I understand why you cannot re-use the feature layer many times, can you expand more on this? – artwork21 Dec 2 '14 at 13:12
  • because my feature class must be inside file GeoDB, and I think the GeoDB do not accept feature layer . Is it right ? Also the features inside feature class is change several time per day . – Nasser AlHinai Dec 2 '14 at 13:15

    The feature layer is not a new layer that is saved to the GeoDB, only a in-memory layer. Once you have the in-memory selection you should be able to delete those related features that are selected (for the feature class). – artwork21 Dec 2 '14 at 13:18

Prior to you adding another requirement for this to be done totally within the original feature class, it seemed possible to do this in a single step using the Select (Analysis) tool that works directly on a feature class.

If you were planning to Select By Attribute where Field = 'X' and then delete the selected records, simply use Select (Analysis) to select records where Field <> 'X' instead.

  • Thank you man for replay > but the Select ( analysis ) tool do not give me expression to select some of feature inside feature class .. – Nasser AlHinai Dec 2 '14 at 13:12
  • I think you must be looking at a different tool - Select (Analysis) accepts an SQL expression. – PolyGeo Dec 2 '14 at 13:17
  • sorry man .. You are right .. the problem with Select ( analysis ) tool is give me different layer in output – Nasser AlHinai Dec 2 '14 at 13:19

    I think you should edit your question to be more explicit about your requirements. – PolyGeo Dec 2 '14 at 13:23
