Water and sewer design: Data editing¶

This section describes the editing functions that you use during water and sewer design in more detail.

You have functions for dynamic editing of geometry in the map and functions for individual or group editing in the properties dialog.

Dynamic editing¶

The dialog and functions described below are available in both plan and profile view. You can find functions for dynamic editing by right-clicking when the mouse pointer is outside the dialog (pointing in map or longitudinal profile).

Finish and save¶

Finish and save

Finishes and saves. You can alternatively press [Enter] or OK in the dialog.

Insert point¶

Insert point

With this selection you can insert manholes (system points) after selecting data type in the dialog.

Procedure

Activate the icon for Insert point... on the context menu
Point and click left mouse button to register the point

In plan, the program automatically retrieves calculated height from the terrain grid. Note that the program takes into account interventions (road body, building pit, etc.) in the model.

In the longitudinal profile, the program retrieves the height from the vertical curvature if this exists. If not, the height is retrieved from top physical layer or 3D line.

Move point¶

Move point

With this selection you can move the system points of the manholes. If you have multiple pipes in the ditch, all manholes in a group (in a group all system points will have identical coordinates) will be moved equally.

Move point will function slightly differently in plan and profile. Manholes where inlet pipe and outlet pipe form a bend in the horizontal plane can only be moved in height, while manholes located on a straight section can also be moved along the line.

Move presentation point¶

Move presentation point

This selection is only active for simple design with manhole groups.

With this function you can move the presentation points of the manholes. This selection does not affect the gradient calculation. The presentation points only hold the placement of the manhole symbol.

The symbol for the manhole is linked to the presentation point's coordinates. After the system points are entered, the presentation points will get the same coordinates (East and North). This means that you can move the symbol afterwards without moving the system point. This is necessary in water and sewer design when you have multiple pipes in a ditch. Then you must present some of the pipes with an offset value to show that there are multiple pipes in the ditch.

Move text¶

Move text

With this selection you can move the manholes' labels (point IDs).

Procedure

Select the point in the list or screen
Choose Move label on the context menu
Point to new location in the screen

Switch between data types¶

Previous data type

Next data type

The dialog can contain many data types. The data type that is active (shown in the list and ready for editing) is marked in the map with orange color. You also see that the system point is marked with a small circle with a cross.

With the buttons for Previous and Next data type you can easily switch between data types in the dialog.

Note

Existing line definition data can be edited either via the properties dialog or via grips. If you want to edit via grips, you must first activate this option (separate icon on the toolbar).

Show dialog box¶

Show dialog box

With this button you can show the properties dialog for the pipe section. Since the dialog box takes up a lot of space, it can be convenient to hide it when you edit the line geometry.

You can turn the dialog box on/off with [Ctrl] + [D].

Editing in the dialog¶

Copy¶

Copies the data that is selected in the list to the Windows clipboard.

This selection is especially useful for simple design with manhole groups.

When the lowest pipe in the ditch is determined, you can easily copy this to the next data type and adjust the values.

Example

Define pipe for bottom of ditch, for example data type stormwater
Select all lines in the list and choose Copy on right mouse button
Switch to new data type, for example data type wastewater
Choose Paste on right mouse button
Select all lines in the list
Point and click left mouse button on the column header for PointID
Choose Generate
Enter new ID with prefix, for example S1
Add corresponding offset value to the levels

Paste¶

Pastes data from the Windows clipboard.

Calculate east and north¶

The function calculates coordinates so that they lie on the line definition, regardless of where you have pointed.

All points that are selected in the list are processed and get calculated new values for X and Y based on profile number.

The calculation is normally done onto the line.

Example:

Side point entered in plan by pointing in the screen.

Calculate height¶

With this function you can recalculate the points' height values. In water and sewer context, this means calculating height on the manhole cover.

Available choices depend on whether you are working in a terrain model or a longitudinal profile.

Choices and normal priority are given below.

Terrain model:

Model surface (top theoretical layer)
Terrain grid
Center line (vertical curvature or 3D line)

Longitudinal profile editing:

Center line (vertical curvature or 3D line)
Advanced section
Top physical layer

You can override the default order (the Normal choice) by selecting from the list.

All points that are selected in the list are processed and get calculated new values for height.

Calculate height from main pipe¶

Calculates height on side point based on height on main pipe. Note that this function does not work for side points placed in manholes.

Adjust gradient¶

You use this function to calculate Level1 and Level2 based on specified value for the gradient. All points that are selected in the list are processed and get new values for Level1 and Level2, except for the first point which determines the starting height.

Adjust gradient backwards¶

Similar to Adjust gradient, but now the last point determines the starting height.

Adjust levels relative to height¶

Use this function to adjust Level1 and Level2 relative to the value in the height column. For water and sewer data types, the height column will indicate top of manhole. In many contexts it is easier to specify manhole depth than absolute levels.

Parallel offset in plan¶

With this function you parallel offset the coordinates in the list.

Note that for simple design with manhole groups, it is the presentation coordinates that are parallel offset.

Interpolate intermediate points¶

This function can be used if you want to interpolate intermediate points. It is the point in the list that is interpolated, i.e., center manhole if manhole dimension is specified.

Height of first and last point selected in the list determines the gradient.

Parallel offset in 3D¶

With this function you can parallel offset both horizontally and vertically. For water and sewer data types, it is Level1 and Level2 that are offset vertically.
