Documenting a trench

Trenches are linear objects used for laying of ducts and cables. All properties of trenches can be described in various ways using attributes in the Trench form. Ducts and cables (with or without their own geometry) can be assigned to trenches. This can be done using workflows. These are started in the workflow explorer or in the context menu of the Trench form under Assignment.

Creating

To create trenches, you can proceed as described in Inserting new objects.

Trenches can be imported from plans (already as trenches), or you can digitize them yourself or include them from imported line geometries (e.g., from the survey).

Modification

Various attributes can be assigned to trenches for a more detailed description. These attributes can be used for stylization in the display model and to modify the presentation in the illustration.

The geometries of trenches can be subsequently modified by checking them out, changing the positions of vertices or adding further vertices. Pay attention to the set and activated object snap. The objects should then be checked in again.

Deleting

Trenches can be deleted in the tabs or via the form. The assignments (duct, cable) will be lost in the process. If ducts/cables are only assigned to this one trench, these will also be deleted (after a corresponding warning).

Disconnecting trenches

If a part of a trench is to be given a different attribute, if another trench branches off at one point or if the occupancy of the trench changes, the trench must be disconnected at this point.

This is done with the Share trench workflow.

The workflow can be started in the NET Planning tab

mceclip10.png

or in workflow explorer > Survey-plan workflows > Share trenches.

If you want to separate ducts within the trench using the duct-connection editor, the trench is automatically disconnected.

The new trench sections receive the same attributes and occupancy as the original trench, but each has its own geometry.

Connecting trenches

If two or more trench sections have the same properties and occupancy, and no other trenches branch off, the trench sections can be connected.

This is done with the Connect trenches workflow.

The workflow can be started in the NET Planning tab

mceclip11.png

or in workflow explorer > Survey-plan workflows > Connect trenches.

The new trench section retains the attributes and occupancy of the initially selected trench, but has the geometry of both of the previously existing trench sections.
