Back in our model, we need to edit our parameters.
By clicking into the Equation column, we can overwrite any of the current values. If the overwrite affects the size in the model, we will be able to see the change immediately.

Although it appears that SIL, SIW, and SRS are constant according to the table, under size parameters, we will configure SIL and SIW to refer to a list of values. SRS will always inherit the depth calculated between the surface and the floor of the structure once the structure has been inserted into a pipe network.
Next we configure Size Parameters. Think of this step as setting the properties of each Model Parameter.
There are three views we can set for size parameters:
- Edit Configuration
- Edit Calculations
- Edit Values
If we first go to Edit Configuration, we can check out the values for Data Storage. Each parameter that was configured with an expression has its Data Storage setting configured to Calculation. Each parameter that was configured with a numeric value has its Data Storage setting configured to Constant. We want to reconfigure that setting for SIL, SIW, and SRS.
Start by clicking on the Data Storage value for SRS and setting it to Range. Click on the Data Storage value for SIL and set it to List, then do the same for SIW. Next change the view to Calculations.
Edit the SIW value. Here is where additional sizes can be added to this parameter's list. The same can be done for the SIL value.
Edit the SRS value. We configured this to be a range value so that we could specify minimum and maximum allowable depths for this structure. Remember that this actual value is calculated when the structure is added to the pipe network.
