      Calculation parameters for hot water and cold water circulation are specified in the Circulation area under Calculation.
    - Pressure boosting (design options for drinking water)
      In the Pressure boost ing area under Calculation, information on the average pressure drop and settings for the pressure boosting system are specified.
    - Apparatus (design options for drinking water)
      In the Apparatus section under Calculation, the maximum permissible apparatus pressure loss is specified for individual apparatus types.
    - General (Drinking water design options)
      In the General area under Material, you define settings that influence the material determination.
    - Component properties (design options for drinking water)
      In the component properties area under Material, settings for determining the material for the pre-wall elements are specified.
  - 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.
  - 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.
