SettingDescription
Place By
  • Line – places curtain wall in a straight line defined with the data points: a start point and an end point.
  • Arc - By Center – positions the curtain wall by three points: an endpoint, the arc center point, and a point that defines the sweep angle.
  • Arc - By Edge – places the curtain wall by three points on the arc edge.
  • Curve – places a curved curtain wall system. Creates a segmented multi-radius curved curtain wall, that can be composed of various curves. The curves are controlled by data points placed at each curve's apex.
  • From Element – places curtain wall system along the selected drawing element.
Height Sets the curtain wall frame height.
Side Offset Sets an offset distance and direction for wall segments which is parallel to a line defined by two placement data points. Direction can be set by using the Left / Right option menu; or by setting a negative distance for Left offset and a positive distance for Right offset.
Direction Sets the direction in which the curtain wall is extruded. The sub-options are Left or Right.
Base Offset Sets the Z axis distance between the elevation of the active floor and the elevation of the item being placed (usually the bottom surface). Base Offset can be a negative value.

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.
  • ( Match Element Properties) - Sets the current active placement/modify dialog settings to match the parameters of an existing, selected catalog item instance in the model. This saves a good amount of time when placing catalog items that need to identically match those that already exist.
    Note: The existing catalog item instance must be of the same catalog type selected with the Catalog Item Selector for the parameters to be matched.
  • (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.
  • (Save Catalog Item As...) - Used to save a copy of the selected catalog item as another catalog item (the default name adds the prefix " Copy of " <current catalog items name>). Opens the Save As dialog where catalog item definitions can be named before saving them to the DataGroup System.
Note: The Save Catalog Item and Save Catalog Item As... tools perform administrative tasks on DataGroup System catalogs. Administrators and users may want to hide the tool icons to avoid incidental or unwanted changes to their firm's dataset by setting the user configuration variables BB_CATALOGITEM_ADMIN_IN_PLACECMDS and BB_CATALOGITEM_SAVEAS_IN_PLACECMDS to "0", respectively.
Preview Displays the selected catalog item in the preview window. This display changes and the preview updates as various options are chosen. A right-click in the Preview opens a Show/Hide Viewing Tools option menu:

    • Isometric
    • Right Isometric
    • Top
    • Bottom
    • Left
    • Right
    • Front

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.
