Unselecting features using Model Builder

StevenGraf1

I have tried so many different things to try and unselect some of my data in my model and I can't get it to work. It anyone can help I would much appreciate it. I need to unselect the features (places (2)) that are contained in the counties (counties(2)) that were first selected.

Thanks

I think I got it. I created a new model, you can find it next to your model.
You can run it as a tool and place points inside counties, just load your data into ArcMap before running it.

Hi Steven,

In Select Layer by Attribute tool properties choose CLEAR_SELECTION for Selection type.

I'm using version 10.1. There is no Clear_Selection. There is Remove_Selection but I can't get it to do what I want.

AkosKisreti1

I'm using 10.1 too. Have you installed SP1?

StevenGraf1

I just noticed that Clear_Selection is on the Select by Attribute query but not on the Select by Location query.

I will try to modify my query using the Select by Attribute and report back if I can get it to work.

StevenGraf1

When I use the Clear_Selection, it clears all features for some reason. ESRI should add a command to the Selection Type - Switch to New Selection (removes previous selection) instead of keeping all previously selected areas...I am still stumped on this problem.

AkosKisreti1

Could you share your model and data?

StevenGraf1

I put a label in there describing what needs unselected. This is a different model from the first one I posted. I got what I needed unselected in that that one. This model has an extra step that I need unselected.

Thanks, I will have a look at it, but your Select_Event FC is empty. Could you send it again?

Also could you specify the criteria again, so I can fully understand what you want to be selected at the end.

StevenGraf1

The select event FC doesn't need to be populated because I am selecting things interactively. I needed it to make a layer file to link the variable 'feature set' to for the schema.

Basically what I need to do in this model is select a point interactively (for some reason you have to choose at least 2 separate interactive points) and select all the surrounding counties that surround the surrounding counties. Does that make sense? i.e. select all those places that are 2 counties away while unselecting every thing else. This is just a generic model that I will be using as a template to find resources within a certain geographic area.

***Be sure to refresh the map or else the selection won't appear. Another minor glitch in the software.

If this doesn't make sense I can try to think of a better way of explaining it.

1. Create two layers based on the same Counties feature class. I will call them Layer 1 and Layer 2 to keep it straight.

2. Select your County of interest in Layer 1. Use the Create New Selection option is Select By Attributes or get a user selection.

3. On Layer 1 Select By Location on itself (Layer 1) and apply the Intersect option without any buffer or a very small positive buffer (say 1 foot) and select against itself. This will be the selection of the County itself plus every County that adjoins the original County. Use the Create New Selection option.

4. Select by Location against Layer 2 using the Layer 1 feature selection as the location to base the search on and apply the Intersect option without any buffer or a very small positive buffer (say 1 foot). Use the Create New Selection option. This will be the selection of every County that is out as far as 2 Counties away from the original County including all Counties within that boundary.

5. Select by Location against Layer 2 using the Layer 1 feature selection as the location to base the search on and apply a -1 foot (or very small negative) buffer to the selection. Use the Remove From Selection option. This will remove all Counties that included the County itself and the first ring of Counties surrounding it (Layer 1 Selection). Layer 2 now contains every County that is 2 Counties away from the original and only those Counties.

6. To transfer the selection of Layer 2 back to Layer 1 use Layer 2 as the feature selection you want to select against Layer 1 and apply a -1 (or very small negative) buffer to the Layer 2 feature selection. Use the Create New Selection option.

No new features had to be created. This assumes your County layer is topologically correct and that no gaps or overlaps exist along any shared border between any two Counties.

This can be done with real layers in a map or with inmemory layers, so Layer 1 could be a real map layer and Layer 2 could be an inmemory layer if you don't want it to actually appear in your map, and by using step 6 the final result will appear in Layer 1 in your map.

These are the steps you would have to follow to do this manually in Desktop to achieve the effect you want (except that in Desktop there would not be any inmemory layer and you would have to have 2 real layers that were based on the same feature class in your map).

Thanks for taking the time to look at it! I understand what you did in the model but it's not working.

StevenGraf1

Richard, I got to step 4 and tried to run the model just to see if it would work up to that point and it didn't. I did have to change the step 2 Select by Attribute to Location to select a point interactively. I tried both methods of Interact (with and without the buffer) and neither worked.

Maybe selecting against itself only works in Desktop and not ModelBuilder, so just go from Layer 1 to Layer 2 instead of Layer 1 to Layer 1. Just keep track of where the selection I described is located and keep transferring selections back and forth until you have a selection in the correct layer at the end.

Here is a model that does a similar thing for the beginning steps. Notice that I used two separate instances of the same feature class to create the layers (The top two Make Layer tiers). That may make all the difference.

Anyway, I have a model that does something very similar and it keeps selecting a feature class against itself in two different layers to test that more than 25 property owners other than the original case owners exists within a buffer distance of the case parcels. I just keep transferring selections back and forth between the two layers based on the same feature class.

I have tested my model and it worked, so what error did you get?

Did you check if the paths to the data was correct?

StevenGraf1

Akos, Thanks for correcting my model. I'm not sure why it wasn't working the first time but I redownloaded it again and corrected the sources again and it worked.

Thanks to all!
