Appendix
- Dialogues and additional information
  - Wastewater lifting unit
  - Design options (waste water)
    Drawing-specific settings relating to your calculation are set in the Design options dialogue.

    Drawing-specific settings relating to your calculation are set in the Design options dialogue.
  - Design options (drinking water)
    Drawing-specific settings relating to your calculation are set in the Design options dialogue.
  - Construction stages
    You can divide a drawing into construction stages so that you can later create a material extract according to construction stages.
  - Component properties
    In the Edit and Calculate work perspective, your selection in the drawing is highlighted in colour. Section properties and component properties can be displayed and edited differently from the global project settings.
  - Component filter
    The component filter allows you to quickly filter the selected components in the drawing.
  - Drainage areas
    The Drainage areas window in the Drainage section is divided into two tabs.
    - Roof areas
      - Add roof area
        Use Add area to create a new roof area in the tabular overview of the Drainage areas window on the Roof areas tab.
      - Delete roof areas
        Delete removes selected roof areas from the table overview. In addition, the associated roof area polygons are removed from the drawing in the floor plan drawing.
      - Placing drains
        The Place drains function provides you with intelligent placement routines for roof drains in floor plan drawings. Customisable default settings including plausibility checks of the value entries are made, taking individual technical specifications into account.
      - Hatching roof areas
        Provide the roof areas in a floor plan drawing with a grey hatching for an overview.
      - Overview of roof areas
        The tabular overview in the Drainage areas window on the Roof areas tab displays information on all roof areas created in the drawing.
        Designation column
        The Designation column in the Drainage areas window on the Roof areas tab displays the unique identifier of the roof area.
        Area column
        The Area column in the Drainage areas window on the Roof areas tab shows the total area of the individual roof areas.
        Drainage coefficient column
        The Drainage coefficient column in the Drainage areas window on the Roof areas tab shows the peak drainage coefficient C_S of the roof area.
        Target discharge column
        The QSoll column in the Drainage areas window on the Roof areas tab shows the calculated target discharge in l/s.
        Setpoint discharge Not. column
        The QSollNot. column in the Drainage areas window on the Roof areas tab displays the calculated target discharge in l/s.
        Water level column
        The Water level column shows the water level in mm for roof areas without emergency drainage.
        Column Emergency water level
        The column Emergency water level in the Roof areas window on the Roof areas tab shows the water level in mm for emergency drainage.
        Maximum permissible damming height column
        The Maximum permissible accumulation height column in the Drainage areas window on the Roof areas tab shows the accumulation height in mm, which must also be taken into account for the maximum permissible surface load for the roof construction. You can adjust this dam height by entering it in the input field.
    - Open spaces
  - Find function
    CALHYDRA has a parameterised search function that supports you when searching for drawn sections and components in the drawing and when selecting products.
  - Hydraulics report
    With the preview of the calculation output, CALHYDRA supports you in customising the calculation output.
  - Mass extract
    With the preview of the mass statement, CALHYDRA supports you in customising the printout of the masses.
  - Material editor
    With the material editor, CALHYDRA supports you with convenient and fast determination of your dimensions.

  - Project data
    The Project data dialogue contains project information for the current project, for example for the project cover sheet or to determine the rainfall donations.
  - Simulation
    The simulation is divided into a circulation simulation for hot and cold water and a simulation of a cold water hygiene system.
  - Section properties
    In the Edit and Calculate work perspective, your selection in the drawing is highlighted in colour. Section properties and component properties can be displayed and edited differently from the global project settings.
  - Insert drawing reference
    The Insert drawing reference function guides you through the settings for inserting a drawing reference.
  - Water softening system

Area column

The Area column in the Drainage areas window on the Roof areas tab shows the total area of the individual roof areas.

In a floor plan drawing, the area is determined automatically based on the size of the roof area polygon and can be edited. The manual determination of the area can be recognised by the blue checkbox.

Note:

The area can be reset to the drawn roof area size by right-clicking on the blue checkbox.

In a schematic drawing, the area must be entered manually and is not predefined.

Important:

The roof area entered here also influences the precipitation area of individual roof drains, which is displayed in the component properties. The precipitation area displayed in the component properties is automatically calculated and displayed based on the number of roof drains assigned to a roof area and the area entered in the Drainage areas window on the Roof areas tab.

Attention:

You can overwrite and define the precipitation area of individual roof drains in the component properties. However, this has no effect on the area in the Roof areas tab.

Tip:

To sort individual columns, click on the column headers in the table to sort the entries in the respective column in ascending or descending order.
