I have one basic question , when you create custom model using model builder in ArcGIS. It should be used with ArcMap or ArcCatalog? Reason I am asking this question is I have created a model and I am setting it "Store relative path names" and I have defined a directory structure for the same. Now the problem is in ArcMap when you right click on "ToolBox" it will allow you to add toolbox and you can select your tool from the specific location whereas in ArcCatalog it creates Tool (.tbx) at C:\Users\\AppData\Roaming\ESRI\Desktop10.0\ArcToolbox\My Toolboxes folder. Where I am not able to access the relative scripts because I will not have any absolute path and it should not be absolute.
Also can someone share the difference between ArcMap and ArcCatalog?
Any idea or suggestions on this?
