Applying Element Annotation

Element annotation functionality allows the display of values for user-selected attributes in the drawing pane. These values are dynamically updated when the current time step is changed.

If you’ve already completed Part 4 of this lesson, you can continue using the same model. Otherwise, begin by clicking the File/Open button; then, browse to the C:/

Program Files/Bentley/SewerGEMS V8i/Lessons folder, highlight Lesson_5_5.swg, then click Open.

1. Click the Compute button, then close the Calculation Executive Summary dialog.

2. Annotation is assigned through the Element Symbology manager. If you are using the default workspace configuration, the Element Symbology manager is located directly below the toolbars on the left side of the dialog. If not, click the View menu and select the Element Symbology command. Highlight Conduit and click the New button, then select New Annotation from the shortcut menu that appears.

3. In the Annotation Properties dialog that appears, change the Field Name to Velocity. In the Prefix field, type in Vel: (with a space after the colon).

4. The X and Y Initial offset fields allow you to define, respectively, the horizontal and vertical distance between the element and the annotation. A positive value for Initial X Offset will cause the annotation to be placed to the right of the element at the distance specified; a negative value will cause the annotation to be placed to

the left of the element. A positive value for Initial Y Offset will cause the annota-tion to be placed above the element; a negative value will cause the annotaannota-tion to be placed below it. Enter a value of -5.00 feet for the Initial Y Offset.

5. The Initial Height Multiplier allows you to increase the size of text used for the annotation. Change this value to 0.750. The Selection Set control allows you to apply the current annotation to only those elements contained within a previously defined selection set. Leave this value at <All Elements>. Click the OK button.

6. In the EPS Results Browser, click and slowly drag the time slider to the right.

Note that the velocity annotation values display the updated value for the current time step as it changes.

7. In the Element Symbology manager, click the New button and select New Anno-tation from the shortcut menu that appears.

8. Change the Field Name to Hydraulic Grade. Enter HGL: (with a space after the colon) in the Prefix field. Change the Y Offset to -8.00. Change the Initial Height Multiplier value to 0.750. Click the OK button.

Lesson 5: Presenting Calculated Results

9. Note that the hydraulic grade line value is now displayed below the velocity annotation. However, the two annotations slightly overlap. High-light the Hydraulic Grade annotation node in the Element Symbology manager and click the Edit button.

10. In the Annotation Properties dialog that appears, highlight Hydraulic Grade in the list pane on the left side of the dialog. Change the Y Offset to -11.00 and click the Apply button.

Note the Initial Offset and Initial Multiplier checkboxes. When these are checked, the settings for the annotation that is currently highlighted in the list pane will be applied to all of the elements with that particular annotation (in this case, all conduits). If you have manually moved some of the annotations in the drawing pane, you should clear the Initial Offset checkbox so that the new settings won’t interfere with your manually repositioned annotations.

11. In the EPS Results Browser, click and slowly drag the time slider to the right to see how the values change over time.

12. In the Element Symbology manager, you can create Theme Folders to organize the various annotations for an element type. Highlight Conduit and click the New button, then select New Folder from the shortcut menu that appears.

13. Highlight the newly created folder and click the Rename button. Enter the name Calculated Results.

14. Click on the Velocity annotation label and hold down the mouse button, then drag the mouse cursor to the Calculated Results folder. Your mouse cursor will change to a drag object icon. Release the mouse button to

place the Velocity annotation in the folder. Repeat this procedure with the HGL annotation.

15. The checkboxes next to each node in the Element Symbology manager list control the visibility of the associated object in the drawing pane, as follows:

The checkbox next to the Conduit node (and the corresponding checkboxes next to each of the other element types) controls the visibility of conduit elements in the drawing pane.

The checkbox next to the Label node controls the visibility of conduit element labels in the drawing pane.

Lesson 5: Presenting Calculated Results

The checkbox next to a folder controls the visibility of all annotation definitions within that folder. In the case of the Calculated Results folder, it controls the visi-bility of the Velocity and HGL annotations for conduit elements in the drawing pane.

16. Clear the checkbox next to the Calculated Results folder. Note that both the Velocity and HGL annotations disappear from the drawing pane, while the Label annotation is still displayed. Click the checkbox next to the Calculated Results folder to turn the annotations back on.

17. The results annotations may now interfere with the visibility of other elements and labels. Manually reposition the element labels if this is the case, so that all of the labels are clearly visible (To learn how to manually reposition labels, see “Part 3:

Moving Element Labels” on page 3-62). Your model should now look like this:

This concludes this part of the lesson. The next part continues where this part leaves off, so you can keep the same project open if you plan to continue immediately. If you plan to begin the next part at a later time, you can either save the current project or use the Lesson_5_6.swg project located in the C:/Program Files/Bentley/SewerGEMS V8i/Lessons folder.
