This group of functions contains commands that are used to define pipe level line. Before you start to define pipe invert,
it is important to set invert position regarding cross section of the pipe.
The invert position can be set as the following:
Methods
Single Level line elevation will be input separately for each node and according to the selected
terrain number. It is possible to calculate the section slopes immediately if the option “Set slopes” is active. The inserted
values have to be manually set with button “Save data”. The arrow button in the lower part of the dialogue is used to step
through the previously made selection set.
Linear Interpolation Method to define level line elevations linearly between nodes inside of the selection set. The nodes
have to be connected between each other by sections otherwise the interpolation is not possible.
From slopes This option of inputting the level line elevations defines level line elevation in starting node of the selected
work area, and set the slope toward the ending node to calculate all elevations for the nodes between.
Constant depth below terrain With this method a common level line elevation (depth) will be set for all nodes inside of the
selection set according the selected terrain number. Usually this option is mostly used for water distribution systems.
Position on level line The reference point for the level line will be only set by this option. The reference point is used
also to align the pipes.
