For more information on the various methods of adjusting parameters for a group of network objects, see Editing Object Parameters.

This is how you use the various parts of the dialog:

Network Objects

Choose whether you want to adjust nodes, pipes or subcatchments.

Field

Select the field you want to adjust. The list uses the field name from the database. The lower box displays the name you usually see on the grids and property sheets. See Network Data Fields for a list of field names.

Object Types

Once you have chosen a field, the types of node, pipe or subcatchment for which this field is relevant are listed. You can uncheck types you do not want to change.

Adjustment Value

Enter the new value for the field here. For numeric fields you can replace the current value or adjust it by a factor. See below for more.

These are the adjustment options available for numeric fields:

Adjust by an absolute value

The amount entered is either added to or subtracted from the field for each of the selected objects.

Adjust by a percentage

The field is adjusted by either adding or subtracting the percentage.

Multiply by a factor

The field is multiplied by the factor.

Divide by a factor

The field is divided by the factor.

Adjustment Direction

If the option chosen was either Adjust by an absolute value or Adjust by a percentage, select whether the adjustment increases or decreases the value.
Rounding Rules

When adjusting integer values by a percentage or using a multiplier, non-integer outcomes are always rounded towards zero. For example, a value of 3.6 is rounded down to 3 while a value of -3.6 is rounded up to -3.
