To create profiles , your System A dministrator must first provide pre-defined profile definitions. You can select the profile features, as for example sections and manholes of a wastewater network, and the profile axis in the map. Use either of the following selection processes.
Topological Selection With Intermediate Features
Use Topological Selection to specify the start and end feature, as well as an intermediate feature. The function selects all network features between these points by calculating the shortest path, according to the following guidelines:
- Between start point and the first intermediate point.
- Between the first intermediate point and the second intermediate point.
- Between the last intermediate point and the end point.
Feature Selection in the Map
Use Feature Selection to select lines and points. You can draw a window to select multiple features.
Profile Axis
If you do not specify an axis explicitly, a default axis is used. The default is calculated differently, depending on the feature selection process. Alternatively, you can specify the profile axis in the map.

Determination of Default Axis |
|---|---|
|
Topological Selection With Intermediate Points |
Determines the axis by network tracing. See also Topological selection. |
|
Polyline Digitization |
Digitizes the axis in the map. |
The default axis can be determined only if the selected features are valid. The default axis cannot be created in the following cases:
- The features are not connected.
- The point features are not on the line.
- The features are connected, but the direction cannot be determined. In this case, you are prompted to specify the start feature.
When the main features and the axis have been selected, you can draw the profile.
Invalid Features
During the profile calculation, the system validates the selected main features. If invalid features are detected, use the Feature Explorer, the toolbar, and the shortcut menu to process the features.
Invalid main features
- Points that cannot be vertically projected on the profile axis.
- Point and Lines without height information.
