An important feature in all modeling software is the ability to present results clearly. This lesson outlines several of SewerCAD’s reporting features, including:

• Reports - Displays and prints values for any or all elements in the system.

• Element Annotation - Dynamically presents the values of user-selected variables on the drawing. • Profiles - Graphically shows how HGL and elevation vary throughout the gravity portions of the

sanitary sewer.

• Color Coding - Assigns colors to values for a variable and applies them to the appropriate locations on the plan view for a quick diagnostic on how the system is working.

If, at any time during this lesson, the program asks, "Do you wish to reset all calculated results to N/A?" click NO.

Part 1 - Reports

For this lesson, we will use the system designed in Lesson 3. If you did not complete Lesson 3, you may also use the file lesson4.swr, or lesson4.dwg in AutoCAD. This file is located in the SWRC / Lesson directory. After opening the file, select the "Design Trial #2" scenario from the Scenario toolbar. Click the GO button and run a regular analysis

When the Results dialog appears, notice that the Results report can be saved to a file or printed by using the buttons in the top left corner. This report displays key properties of each element on a formatted page. Click Close. The results for the last run can be accessed at any time by clicking the GO button in the toolbar and clicking the Results tab.

Open the Manhole Editor for MH-1. Click the Report button at the bottom of the dialog and select Detailed Report from the pull-down menu to view a formatted summary report of manhole MH-1’s properties.

Every element has a report with the same general format, which includes the name of the calculated scenario and a series of tables describing the element’s properties and results in detail. You can print this report or copy it to the clipboard using the buttons at the top of the dialog. The report will print or paste into a word processor in the exact format seen on the screen.

Click the Close button on the report and click OK to exit the Manhole Editor.

To print the detailed reports for several elements at one time, select Report / Element Details from the pull-down menus. In the AutoCAD version, the crosshair changes into a pickbox. Using the pickbox, select elements from the drawing space that you want SewerCAD to report on and right-click to bring up the list of Detailed Reports. In the Stand-Alone version, the list of elements will appear immediately. From this dialog you can select multiple elements and print them to a printer. If you wish to select multiple elements based on some criteria, click the Select… button to go to the Selection Set dialog. Click Cancel to return to the Detailed Reports dialog. You can click the Print button to print all of the reports for the selected elements. Click Cancel to exit the dialog.

Select Report / Element Results from the pull-down menu. In the AutoCAD version use the pickbox to select the elements for which you want a report. Then right click once to bring up the list of Results Reports. In the Stand-Alone version, the list of Results Reports will appear immediately. From this dialog you can print or copy/paste the Results Report for any element. The Results Report contains all of the results calculated for the selected element. Again, if you wish to select a group of elements based on some criteria, click the Select… button. Click Cancel when you are done.

Select Scenario Summary from the Reports pull-down menus. This report summarizes the alternatives and options selected in the current scenario. Click Close.

Now select Report / Project Inventory from the pull-down menus. This report will tell you the total number of each type of element and the total length of pipe in the system. Click Close.

Part 2 - Tabular Reports

Tabular Reports are extremely powerful tools in SewerCAD. These reports are not only good presentation tools; they are also very helpful in data entry and analysis. When data must be entered for a large number of elements, clicking each element and entering the data can be very tedious and time consuming. Using the tabular reports, elements can be changed using the global edit tool, or filtered to display only the desired elements. Values that are entered into the table will be automatically updated in the model. The tables can also be customized. Columns can be added or removed, or you can display duplicates of the same column with different units. The tabular reports can save you an enormous amount of time and effort.

To open a tabular report, select the Report / Tables from the pull-down menus or click the Tabular Report button on the toolbar. Select the Gravity Pipe Report from the list and click OK.

Tabular reports are dynamic tables of input values and calculated results. White columns are input values and yellow columns are non-editable calculated values. When data is entered into a table directly, the value in the model will be automatically updated. These tables can be printed or copied into a spreadsheet program.

Two very powerful features in these tables are Global Edits and Filtering. Suppose we find that the downstream inverts of all 250 mm pipes needs to be 10 cm higher. It would be tedious to go through and re-enter every pipe invert elevation, particularly when dealing with a large system. Instead, we will use the filter tool in this example to filter out the 250 mm pipes, and the global edit tool to add 10 cm of elevation to just those pipes.

Right-click the Section Size column and choose Filter / Quick Filter from the pop-up menu. We want to filter to display only the 250 mm pipes. To do so, set the Column field to Section Size, set the Operator to =, and set the Value field to 250 mm. Click OK.

Now we will use the Global Edit tool to modify all of the rows in the table. Right click the Downstream Invert Elevation column and select Global Edit. Select Add from the Operation list and enter 0.1 m into the Global Edit text box. Click OK.

To deactivate the filter, right click anywhere in the dialog and select Filter / Reset from the pop-up menu. Click Yes to reset the filter.

You may also wish to edit a table to add or remove different columns. This can be done using the Table Manager. Click the Options button and select Table Manager. Select the Gravity Pipe Report from the list and click the Table Management button. In the pull-down menu there is also a New option that would allow you to create your own table. Any tables you add will be saved for use with other projects. For now, click the Edit option.

Use the [ < ] and [ > ] buttons to add or remove columns from your table. For this example, select Average Velocity from the left and click the [ > ] button to add it to the list of selected columns. You can adjust the order of the columns by using the arrows, or by simply dragging and dropping items.

You may also wish to have two columns with the same attribute but with different units. To do this, check the Allow Duplicate Columns box. Then you can create the same column twice and just change the units. Click OK when you are done, then click OK in the Table Manager. The new table will have the added columns.

If you have made multiple columns and wish to apply separate units to the two columns, click the Options button and select Use Local Units. This option allows the tabular report to have units independent of the project and local to the table. Without this option switched on, changing the units of pressure from kPa to psi in the table would change the unit for pressure throughout the project. The Use Local Units option is ideal for displaying the same variable with multiple units within the same tabular report. Click Yes in the warning box that appears indicating that you wish to switch to local units. Then change the units on any of the numeric columns by right-clicking the column and selecting the Properties option. Change the units in the list box and click OK.

Click Close.

Part 3 - Element Annotation

Click the GO button and rerun the analysis to update the results to reflect the changes in invert elevations.

Select Tools / Element Annotation from the pull-down menu, or click the Annotation button on the toolbar.

This will activate the Annotation Wizard. Select the elements you wish to annotate. In this example, we will add annotation to the manholes and pressure pipes. Select these elements from the list. Click Next. This dialog allows you to choose the attributes you wish to annotate for the specified element type. The Attributes column is used for selecting the attribute you would like to annotate. The Mask is a template of how the annotation will appear on the screen. The %v and %u options are added to display and control the value and units associated with the attribute. For this example, we will add annotation for the hydraulic grade line entering and exiting the manhole. In the first row of the attribute column select Ground Elevation from the list. In the second row of the attribute column select the Sump Elevation option. Click Next.

Add Pressure Flow and Pressure Pipe Headloss annotations for pressure pipes in the same manner described above. Click Next.

This is the last dialog of the Annotation Wizard. Check your annotations in the summary. If there are any errors, click the Back button to go backwards in the wizard and make any necessary changes. Click Finished.

The drawing will now display all of the annotations. You can try changing the properties of an element and recalculating. The annotations will update automatically to reflect any changes in the system. You can also click and drag the annotation to move it. In the AutoCAD version, click the annotation and then click the grip to move it, or use an AutoCAD command such as Move or Stretch.

Part 4 - Create a Plan and Profile

To create a plan view of the sewer system, select Report / Plan View / Full View from the pull-down menu. This will create a plan of the entire system regardless of what the screen shows, while the Current View option will create a plan of exactly what is displayed in the window at that moment.

The Plan View will be put into a separate window that can then be printed or copied to the clipboard. If you click the Copy button, you can then paste the plan view into a word processor. Click Close. Another method that can be used to create a plan view in the Stand-Alone version that can be opened in AutoCAD is to select File / Export / DXF File from the pull-down menu. This will create a .DXF file of your network that you can import into AutoCAD. In AutoCAD, use plan views as a quick way to develop simple scaled views of your primary network.

To create a profile view, select Tools / Profiling from the pull-down menu, or click the Profile button on the toolbar. This will open the Profiles dialog. From this dialog you can create multiple profile views for a network. For example, we can create two profiles, one from MH-2 to WW-1 and another from MH-1 to WW-1. Once the views are created you can go back to the Profiles to access and modify them.

Before creating a profile you can setup a profile template, which allows you to adjust many of the profile properties such as scale, label orientations, and profile annotations. By doing so, you can you reuse the same set of standards every time you create a profile, hence eliminating having to redo the same work. Click the Templates button on the dialog. This will bring up the list of all available profile templates. Click the Add button and enter "Lessons Template" and click OK.

For the sake of the lesson, we are going to make two simple changes to illustrate the concept, but as you can see by scrolling through the tabs the range of customization is extensive. Click the Layout tab. In the Node section click the Leader check box to create a leader line from the node annotations to the nodes that they are describing.

Click the Drawing tab and change the Axis Labeling to Both. When this option is toggled the elevations on the Y-axis will be displayed on both sides of the profile. Feel free to play around with the other options, or adjust the annotations. Click OK to exit the Template dialog. Click OK a second time to return to the Profiles dialog.

Click the Profile Management button and select Add. In the Label field enter "MH-2 to WW-1," and click OK to open the Profile Wizard.

In Step-1 you select the elements to be included in the profile. Click the Select From Drawing button. This will open a plan view of the drawing. Note, that you can still use the zoom tools from the main toolbar. In this case click P-3 and P-2, so they are both selected. You can tell this when the lines delineating the pipes become dashed. In the following image the annotations were turned off for the sake of clarity.

When you have selected the elements right-click the mouse and select done or click the ESC key. You should see the elements you selected listed in the Elements section. When you are finished click the Next button.

In Step-2 you can select the template to be applied to the profile. Select, Lessons Template from the pull- down menu and click Next.

This dialog allows you to set the scale for the axes, as well as the direction of the profile. These same options are accessible through the Options / Profile Options selection in the Profile Window. For this example, use the default values and click Finished.

The Profile Window will open. You can quickly move the labels to different locations by simply clicking and dragging them. Use the zoom buttons at the top to zoom in to any portion of the profile. The HGL depicts all of the flow profiles within the pipe.

You can customize annotations for the elements in the profile. To do so, click the Options button and select Annotation… Establishing the annotations is exactly the same as setting up annotations for the plan view. In this case lets add an annotation displaying the ground elevation at the wet well.

Click the Next button until you get to the Wet Well Annotation section. Select Ground Elevation as an attribute in the blank row, and click finished.

Once the profile is made, it can be exported as a .DXF file, printed, or copied to the clipboard. To export the profile as a .DXF file, click the File button and select Export to DXF. In AutoCAD, you can export profiles to the drawing by selecting File / Export to AutoCAD. These exported profiles do not

automatically update as the model information changes. Click Close when you are finished.

Part 5 - Color Coding

Select Tools / Color Coding from the pull-down menus, or click the Color Coding button on the toolbar.

The Color Coding dialog allows you to set the color coding for links, nodes, or both. We will color code links only in this example. From the Color Coding choice list, select the Length attribute. You can enter any range of values for length into the table. Click the Calculate Range button to get the minimum and maximum values for the variable displayed at the top of the dialog. Or you can click the Initialize button and the model will update the color coding automatically. Click OK.

We can add a legend to the drawing by clicking the Insert Legend button and then choosing the Link Legend option. Click anywhere on the drawing space to place the legend. In AutoCAD, accept the defaults when prompted about scale and legend.
