I want to compare an input number to a constant number (<=), but I can't find the tool to do it in ModelBuilder. I have seen in an ArcGIS help website that a function named "if value is" exists but I don't know how to find it.

Do anyone know how to do it?

    do you work with raster or vector ? Is your input number inside the dataset (pixel or attribute value) or a meta-variable (e.g. count of seclected entities, extent of the layer, existence of data like on your link...)

  • Hi, my input variable is the count of an occurence

    please edit your question with more details about the occurence. The tool that you need could depend on the type of variable.

  • I have a set of points in a table that are grouped, in fact I have a feature named group in which the number of the group of each point is written (groups from 1 to 8). All my groups have a size of 6 except one, I want to find this group. If Value (of the size of my group) is (not) 6 then ... But I can't find this tool, it's not that I can't use it, it is that I can't find it.

The If Value Is tool is part of the ModelBuilder toolbox of ArcGIS Pro. To confirm that see An overview of ModelBuilder tools for ArcGIS Pro.

If you cannot find it then I suspect that you are using ArcMap instead. As you can see in An overview of the ModelBuilder toolbox for ArcMap that tool, and none of the Logical tools are present in that earlier architecture.
