Place Component Settings

The Place Component settings are activated when dynamically placing Mechanical discipline components like duct, pipe, fittings, valves, diffusers, grilles, pumps, equipments and inline devices. The tool interface is common to all placement tools, and appears when a placement tool is selected from the ribbon. All mechanical disciplines, include HVAC and Plumbing, as well as LPG and Fire protection are supported.

  • Ribbon: Building Systems Design > Plumbing > Place Plumbing Systems > > [plumbing component]

Use the Placement settings together with the Place Component settings dialog to set user properties like inlet/outlet sizes, component dimensions, flow rates, insulation materials, service type, system ID, and pressure class.

Placement Tabs

Selection of the Place Component tool opens a contextual ribbon tab in the Building Systems Design > ribbon. The Placement tab contains Mechanical common and HAVC/Plumbing discipline related tools and settings used to control the physical placement and positioning of newly placed components.

The Placement tab; Placement, Placement Options, Flex Duct Options and Slope Options tool groups shown.

Note: The Placement tab opens on the ribbon when placing Building elements. The Placement tab contains settings specific to the Building element being placed that are used to define the position, orientation or dimensions of the Building element being placed. Also available on the Placement tab, are a collection of Building common tools selected specifically because of their relevance to the Building element being placed.
SettingDescription
Placement Sets the positional relationship of new linear component with respect to the position of the previously placed segment. Setting supports all nine points of justification. The active point of justification is marked with an arrow.

Use the justification setting to maintain flush route edges, when segments of duct or pipe change size along linear walls or when hanging beneath bar joists. The justification setting determines the exact shape and size of the transition piece that is needed when routes change size.

Note: Justification is disabled for all non linear component types and while in Single-Line mode.
Placement Options
  • Part/Family - When on, part and family definitions of the selected component are assigned to the new component.
  • Orientation - When on, the new component aligns with the end of the selected component.
  • Size - When on, the new component is automatically sized to match the end of the selected component, usually on duct or pipe. E.g. When a tee is slide in (AcuuDraw <R> <I>) to place on a duct or pipe, then its inline sizes to match with that of the duct size.
  • Shape - When on, a new component type is automatically selected to match the shape of the selected component.
    Note: To place damper to another shaped duct, hold <Ctrl> and click will cycle through all the available selection.
  • Exchange - When on, replaces an existing component with the active component.
  • Base Offset - Enabled when a floor is selected in the Floor Manager as a reference plane. Sets the Z axis distance between the elevation of the active floor and the elevation of the component being placed. The value defines offsetting Mechanical components from the active floor, there by allowing to route at an appropriate elevation relative to the active floor.
Flex Duct Options
  • Single-Line Mode – When on, the routing workflow draws the model in single line. The single line mode supports all manipulation commands.
    Note: Justification (Placement) is disabled when Single-Line mode is set on.
  • Type – Sets the connection components to rigid or flexible.
  • Item – As defined by the Type, contains all the rigid or flexible connection instances to use in placing.
  • Flex Length – Sets value as maximum length of flex in the hookup run.
Slope Options Enabled for Plumbing components.
  • Apply Slope – When on, enables Apply Slope tool settings in the ribbon which are applied to the (piping) component being placed in the route.
  • Method - Settings apply the desired slope method.
    • Rise / Run
    • % Percent
    • Degree
    For a selected method the ribbon displays the appropriate labels to the value input control.
  • Slope value input - Enter a value(s) for the amount of slope for the selected method.
    • Rise : Run — Accepts the vertical rise and horizontal run values respectively for Rise/Run slope method.
    • Percentage — Accepts a value in the scale of percentage for % Percent slope method.
    • Slope Degree — Accepts the angular inclination value for Degree slope method.
    Switching the Method to another displays the equivalent slope value.
  • Slope Direction - Direction of slope can be either Up or Down. Slope run direction is defined by the location on pipe of the selection data point.
    • Down
    • Up

Place Component - Properties



Example of Place Component (Duct Component)

SettingDescription
Catalog Type Selector Used to select from available Catalog Types. Selections made here updates the Catalog Item Selector combo box.
Catalog Item Selector Used to select from available Catalog Items. The Catalog Item Selector combo box contains several options and settings designed to make it easier to find the exact catalog item you need to place/change.

A generic example of Catalog Item selector options for searching, grouping and navigating

The Catalog Item list also includes user defined assemblies, and RFA catalog items, if any.
  • Search - Used to search for catalog items by name. Results are dynamically updated in the catalog items list. The searched text is also highlighted in the results.
  • Group By: - Used to list catalog items in groups based on values assigned to specific catalog item properties. Groups can be collapsed and expanded by clicking the down/up arrows on the group name headers. For instance, selecting Group By: > Type for a wall catalog type creates groupings with Schematic, Partition, WallComponent, etc headings. Catalog items which have Type defined as Schematic, Partition, or WallComponent will be listed under those headings. You can also select Group By: > Do Not Group to create a flat list with no grouping. (Exemption Mechanical).
  • (Large Icons) - Displays a representative icon for each catalog item listing.
  • (List) - Displays catalog item listings without any icons.
  • (Float) - When selected, the Catalog Item Selector combo box is detached from the placement/modify dialog, and becomes a separate dialog. You may prefer to have the floated dialog docked and always open over clicking the Catalog Item Selector in the placement/modify dialog for each catalog item selection.
    Note: The main dialog remains open and refreshes the thumbnail and preview in response to the selected catalog item.
    Click the Dock icon to close the floated dialog.
  • Recently Used - Lists catalog items that were recently selected in a "Group". This is useful because when you need to repeatedly place or modify the same catalog items, you do not need to repeatedly browse or search the main catalog items list.
Note: When you make your catalog item selection, it becomes the active part the Family/Part Toolbar.
Catalog Tools A split button located to the right of the Catalog Item Selector contains tools to assist with managing catalog data prior to placement of selected catalog items.
  • (Reset to Defaults) - Resets the selected catalog item property values to the default state as defined in the catalog library.
  • (Edit Catalog Item) - Used to edit the selected catalog item. Opens the Catalog Editor, where you can create and edit new catalog types and catalog items. Catalog Editor can also be used to edit existing data and to view catalog item instance properties and values by definition.
  • (Catalog Item Manager) - Used to manage catalog items library into organizational dataset. Opens the Catalog Item Manager, where you can copy or move catalog items into the dataset, and promoting current catalog items by moving then across workset levels.
  • (Save Catalog Item) - Updates the active catalog item in the DataGroup System catalog library with the values currently shown in the Properties list box permanently changing the defaults for the catalog item.
Note: The Save Catalog Item tool performs administrative tasks on DataGroup System catalogs. Administrators and users may want to hide the tool icon to avoid incidental or unwanted changes to their firm's dataset by setting the user configuration variables BB_CATALOGITEM_ADMIN_IN_PLACECMDS and to "0".
Preview Displays the selected catalog item in the preview window. This display changes and the preview updates as various options are chosen. The preview also changes dynamically with some of the prominent settings on the Placement tab, e.g Height, Rotation angle, etc. A right-click in the Preview opens a Show/Hide Viewing Tools option menu:
  • Zoom In - Zooms in about center of preview.
  • Zoom Out - Zooms out about center of preview.
  • Pan - Moves the preview following the pointer. Click again to stop panning.
  • Fit - Fits the object to the extents of the preview.
  • Rotation - Sets the orientation of the selected item in the preview to one of the standard orientation options:
    • Isometric
    • Right Isometric
    • Top
    • Bottom
    • Left
    • Right
    • Front
    • Rear
  • Display Mode - Sets the display of the selected item in the preview to one of the standard display modes.
    • Solid
    • Wire Frame
    • Visible Edge
    • Filled Visible Edge
For Place workflow, the Hide/Show Preview controls displaying preview of the element currently selected for placement.
Properties list - toolbar Used to manage catalog item properties during placement or modification. Catalog item properties define the catalog item instance in the model, and are accountable in the DataGroup System data management tools. You can place a catalog item with its default property values or you can change property values as needed, place an instance in the model, and optionally save the changes to the catalog.

The Properties combo box contains tools for sorting and searching the properties list:

  • (Categorize) - When on, catalog item properties are grouped in categories based on the catalog type definitions. When off, the properties are listed alphabetically without grouping.
  • (Alphabetical) - When on, catalog item properties are listed alphabetically without grouping. When off, the properties are listed in categories.
  • (Description) - Toggles a description field at the bottom of the placement dialog listing information about the highlighted catalog item property. The information listed includes the property definition display name, internal name, and type definition.
  • Search - Used to search for catalog item properties by name. Results are dynamically updated in the properties list.
Properties list - tables
Information in the Value column rows can be completed by selecting the applicable cell to activate an editor field, an option menu, or a pop up dialog. This data is written to the element properties. Properties displayed with grey text are read only.
Note: Some of these are set in the placement tool's Placement tab, and can be modified there.
The dividing bar between the Property, and Value columns can be moved to change the width of either area. Vertical and horizontal scroll bars are available to adjust Properties panel viewing and the display of data.

Majority of Mechanical discipline properties are provided with schema defined context sensitive options. A downward-pointing arrow icon next to the value field opens a pull-down list of property options. Selecting one of these Context Menu Options opens context menu activated dialog that aids in settings property attributes. The pull-down list also contains Automatic Entry Context Menu Items automatically sets the property without the additional settings or secondary dialog.

The DataGroup property Mechanical Component Properties provide detailed information regarding applicable entries and ranges of values for each property.
