What are model parameters, and why is it important to set them? - ANSWERS-A type of parameter exposed in a geoprocessing model that appears in a model's dialog box and allows for input -Important if you are sharing your model with other users, allow others to run the model from a tool dialog box and add their own data or values as input If a colleague or another user sends you a model, what should you do first with the model? - ANSWERSYou should first validate the model because validation will verify the data inputs and other parameters. Suppose that you want to send your parcel owner notification model to a GIS analyst in another city. The analyst will run the model as is, but they want to add the city's own parcel data and buffer distances. How might you set up this capability in the model before you send it? - ANSWERS-Set the input data element as a model parameter. With the buffer distance, you would first need to create a variable from the distance parameter and then set it as a model parameter. If you set an application-level environment setting, and then you set a model-level setting for the same environment, which environment setting would override the other? - ANSWERSThe model-level setting would override the application-level setting in the hierarchy. What does the shadow under a model element mean? - ANSWERSThe element has already been run. T/F Assume that you have a model-level environment setting applied to your model. If you then set a model-process environment on one of the processes, the model-level environment would override the model-process environment setting. - ANSWERSFalse T/F Model parameters can only be set before you share a model with someone and cannot be set by the person with whom you are sharing the model. - ANSWERSFalse What is the first step in the model planning process and what is the reason for that step? - ANSWERSDetermine your scenario and goal because they will drive the data to be used in the model. What is the difference between tool and model parameters? - ANSWERSTool parameters determine inputs, outputs, and other values for a tool, whereas model parameters make models dynamic when run from the tool dialog box and also allow for user input. Suppose that you set the application-level environment setting for the current workspace to store all your data in the same geodatabase. However, you want the outputs for one of the models to be stored in another geodatabase. What is the most efficient way to do it? - ANSWERSSet a model-level environment setting for the workspace because it will override the application-level environment setting.
If an application-level environment setting is applied to a model, how might you store the output of a Dissolve tool into another geodatabase? - ANSWERSWithin the Dissolve tool, set a model-process-level environment setting to the new geodatabase. You have received a model from another user and try to run it from its tool dialog box, but it displays a message that the tool has no parameters. How would you provide your own input data from the tool dialog box? - ANSWERSRight-click each data element that you want as a parameter and set it as a model parameter.

After the tool runs, the user does not need to do anything else before continuing to the next step of the task.
