Ventilation duct – Start
Branch of from a vertical segment

Example

Suppose you want to start as a branch from an existing vertical duct segment.

Required conditions

Workflow

Ventilation duct

  1. Activate: Standard ToolsClosed

  2. Select the function in Context ToolbarClosed



     The cursor appears as a crosshair.

  1. Point to the vertical duct segment. The ventilation duct is highlighted. A menu lists the available options.

    The indicated height corresponds to the center of the vertical segment, measured from the top of the finished floor.

  2. Select the entry that displays the medium and the height (Z).
    The dialog appears: Give position in flow segment

  3. Define the installation height.

  4. Click OK.
    The dialog appears: Tee
  5. Check the dimensions.
  6. Activate: Automatically start drawing from this Tee
  7. Click OK. You can continue with the next step.
  1. Click . The context menu appears.
  2. Select: Properties
    The dialog appears: Pipe Start

  3. Define the behaviour of the branch ventilating duct . You can determine which settings will be taken from the main line and will move further.

    Setting Effect

    Default setting.

    The branching duct automatically uses the medium of the existing duct segment .

    You can change the medium of the branching duct .
    Setting Effect

    Default setting.

    The branching duct takes over the color and material of the existing duct segment .

    For the branching duct you can select:

    • The color on the tabAttributes
    • The material from the product database with...
    Setting Effect

    Default setting.

    The branching duct takes over the insulation material of the existing duct segment .

    You can change the settings for insulation for the branching duct .

    • Material in the tabInsulation
    • Apply with Use Insulation
    Setting Effect
    Insulation is applied to the duct. The material can be selected in the tab Insulation.
    No insulation is applied to the duct.
    Setting Effect

    The speed level is taken from the previous connection (e.g. from a branch of a tee).

    You can freely determine the speed level. ClosedMore

  4. Check the missing settings (depending on point 3).

    For a better overview, all available medium types are organized into groups.

    Opens the product database and allows the selection of a product.

    Behavior in the pressure loss calculation:

    Setting Effect
    Dimensions will remain unchanged.
    Dimensions can be changed.
    Setting Effect

    The speed level is taken from the previous connection (e.g. from a branch of a tee).

    You can freely determine the speed level.

    Association of the components to the selected velocity level.

    Layer

    Setting Effect
    The object is assigned to its default layer. An individual setting is disabled.
    The status indicates that an individual setting applies to the object.
    Setting Effect

    The layer number is displayed in addition to the layer name. The numbers can be used as a guide and sorting criteria in the manager.

    The selection only contains the layer name.

    Making a setting removes the object from its default Layer and sets the layer association for the object individually. Use Default will then be deactivated.

    DDScad manages its layers in several groups, which are primarily organized by discipline. To be able to specify a concrete layer, first select the group:

    The active group determines which layers are available for selection:

    If you would like to assign the default layer to the object again, select Use Default.

    Opens the dialog Closed Layer select .

    Pen

    Setting Effect
    The object is assigned its default pen. An individual setting is disabled.
    The status indicates that an individual setting applies to the object.

    Making a setting separates the object from its default Pen and sets the pen that is to be used individually. Use Default will then be deactivated.

    DDScad manages its pens in several groups, which are primarily organized by discipline. To be able to specify a concrete pen, first select the group:

    The active group determines which pens are available for selection:

    If you would like to assign the default pen to the object again, select Use Default.

    Opens the dialog ClosedUser Defined Pen.

    Render surface definition

    Setting Effect
    The object uses the default reference according to its object type. An individual setting is disabled.
    The status indicates that an individual setting applies to the object.
    Setting Effect

    The material numbers are displayed in addition to the material name in the selection. The numbers can be used as a guide and sorting criteria in the manager.

    The selection contains only the name of the material definition.

    Material definitions for the active group. With the setting you remove the default material from the product and assign a custom material. Use Default is deactivated in the process.

    DDScad manages its materials into several groups, which are primarily organized by discipline. To activate the material definitions of another group, click on Render surface definition

    If you want to display the object with its default material again, activate Use Default.

    Opens the dialog Closed Render Object .

    Setting Effect

    Insulation is applied to the duct.
    No insulation is applied to the duct.

    Opens the product database and allows the selection of a product.

  5. Click OK. You can draw the course.
