  - 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.
  - Diaphragm expansion vessel
  - Options Wizard (waste water)
    The options wizard guides you through the settings for the design.
  - Options assistant (heating)
    The options wizard guides you through the settings for the design.
    - System temperatures (Heating options wizard)
      The temperatures used on the heat generator and the 3-way valve are specified in the System temperatures area.
    - Material configuration (Heating options wizard)
      The material configuration area allows you to quickly assign different pipe sequences and insulation materials for each section type.
    - Calculation specifications (Heating options wizard)
      The maximum flow velocities and the average pressure drop per network section and valve authorities are defined in the Calculation specifications area.
    - Summary (Heating options wizard)
      The summary of the options wizard provides an overview of all previously made settings.
  - Options Wizard (drinking water)
    The options wizard guides you through the settings for the design.
  - 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.
  - Product sequence or product selection
    In the Product sequence or Product selection dialogue, select the product sequence or a product for components.
  - 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
