  - 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.

Pipe rows (heating design options)

The Pipe rows area under Recording provides an overview of individual pipe systems and enables individual adjustments to be made in the pipe system.

You can select the pipe series(pipe sequence) in the drop-down menu. The individual columns of the table show technical data for the selected pipe system.

Nominal diameter DN
Pipe designation
Outer diameter d_a in mm
Inside diameter d_i in mm
Wall thickness s_R in mm
Pipe roughness k in mm
Delivery length in m
Water content in l/m
Specific heat loss in W/(m*K)
Thermal conductivity of the pipe λ in W/(m*K)

Tip:

Click on the respective column header to sort the individual columns in ascending or descending order.

The definitions in the Active column can be customised using the checkboxes. In the Active column, you can block or unblock individual nominal widths of the selected pipe system.

Note:

The deactivated nominal widths are not used for dimensioning.

The definitions in the Bent column can be customised using the checkboxes. In the Bent column, you can set whether deflections are realised with fittings (elbows/bends) or by bending the pipeline, depending on the nominal width.

Note:

You can enter the deactivated deflections in the section properties.
