Contour Definition

The Contour Definition dialog box contains the information required to generate contours for a calculated network.


Contour
Field	Select the attribute to apply the contour.
Selection Set	Apply an attribute to a previously defined selection set or to one of the following predefined options: All Elements - Calculates the contour based on all elements in the model, including spot elevations. All Elements Without Spots - Calculates the contour based on all elements in the model, except for spot elevations.
Minimum	Lowest value to be included in the contour map. It may be desirable to use a minimum that is above the absolute minimum value in the system to avoid creating excessive lines near a pump or other high-differential portions of the system.
Maximum	Highest value for which contours will be generated.
Increment	Step by which the contours increase. The contours created will be evenly divisible by the increment and are not directly related to the minimum and maximum values. For example, a contour set with 10 minimum, 20 maximum, and an increment of 3 would result in the following set: [ 12, 15, 18 ] not [ 10, 13, 16, 19 ].
Index Increment	Value for which contours will be highlighted and labeled. The index increment should be an even multiple of the standard increment.
Smooth Contours	The Contour Smoothing option displays the results of a contour map specification as smooth, curved contours.
Line Weight	The thickness of contour lines in the drawing view.
Label Height Multiplier	The thickness of contour lines in the drawing view.
Color by Range	Contours are colored based on attribute ranges. Use the Initialize button to create five evenly spaced ranges and associated colors. Initialize —This button, located to the right of the Contour section, will initialize the Minimum, Maximum, Increment, and Index Increment values based on the actual values observed for the elements in the selection set. Initialization can be accomplished by clicking the Initialize button to automatically generate values for the minimum, maximum, increment, and index increment to create an evenly spaced contour set. Ramp —Automatically generate a gradient range between two colors that you specify. Pick the color for the first and last values in the list and the program will select colors for the other values.
Color by Index	The standard contours and index contours have separately controlled colors that you can make the contours more apparent.
OK	When you click OK your settings will be saved but not applied (the drawing view won't refresh). Clicking OK will close the dialog.
Initialize	This button will initialize the Minimum, Maximum, Increment, and Index Increment values based on the actual values observed for the elements in the selection set.
Apply	When you click Apply your settings will be applied (the drawing view will refresh). Clicking Apply will not close the dialog.
Cancel	Closes the dialog without saving or applying any changes.
