Manhole Presentation Rule

Use this dialog to define a manhole figure for points in an application layer.

Available Shapes

The manhole can be presented as:

• Rectangle
• Cylinder
• Cylinder with cone
• Cylinder with eccentric cone

For each shape, you specify different parameters in the dialog. You can enter values directly or retrieve them from attributes in the application layer.

Tip

You can retrieve values from the application layer for all fields. You can also select the property using the button with three dots instead of entering it manually. By using the button with three dots, you can choose from available attributes in the application layer, and the special character is added before and after automatically.

Note

Note that the manhole is presented differently in 2D and 3D views. In 2D, only a simple rectangle or circle is shown.

Reference Heights

You can choose between two reference heights:

1. Bottom inside
2. Top outside

Bottom inside

The center of the manhole bottom is placed at the point object's coordinates.

A* = Manhole cover height, B = Adjustment ring height, C = Cone height, D = Manhole bottom offset, E = Manhole cover top height (height from another point object), F = Manhole bottom inside height (reference point), Red dot* = Measurement point

Top outside

The center of the manhole top is placed at the point object's coordinates.

A* = Manhole cover top height, B = Manhole bottom offset, C = Manhole top height (reference point), D = Manhole height, Red dot* = Measurement point

Manhole Opposite Point

You have three options:

1. East, North, Height from another point
2. Height from attribute
3. Manhole height from attribute

The first option is relevant for the bottom inside height reference. The program then retrieves the height from another point based on proximity (the point must be within the manhole's extent) and code (for example, theme). This will typically be a surveyed manhole cover. The point can also be in another application layer, such as for application layers with a GML schema.

In the second case, you must have a property with the absolute height for the manhole top or bottom, depending on the selected height reference. Typically, you will have a property on the point object, such as TopCoverHeight, where all heights are entered. You can then have the program retrieve the values automatically. Do this by entering the property name in the field with percent signs before and after, for example, %TopCoverHeight%.

In the third case, you must have a property with the manhole's height.

Cone

For the presentation of a cylinder with an eccentric cone, you have several options for specifying the rotation.

With the option East, North, Height from another point, the program uses the coordinates to calculate the rotation angle (direction of the cone). This option is only active for the bottom inside height reference.

With the option Rotation from attribute, you can also retrieve the value from a property. The rotation values must then be given in degrees (mathematical 360-degree system) on the point.

With the option Rotation from another point, the program uses the coordinates to calculate the rotation angle (direction of the cone).

Note

Note that the point object can also have a rotation (you can rotate the cone dynamically on the screen when in 3D with perspective view turned off, using the Rotate around z-axis option in the context menu). The point's rotation is overridden if you have selected Rotation from attribute.

There is also a separate presentation rule for manhole covers. In this rule, the manhole cover can be defined with a thickness, and you can therefore set a corresponding offset so that the manhole and manhole cover are not drawn on top of each other.
