Placement tab

The Placement tab contains stair Configuration and Alignment options used to control the physical placement, orientation and type of stair.

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.

Description

Placement - Stairs Alignment

Sets the controlling anchor point for stair placement.

Top:	Top Left	Top Center	Top Right
Landing:	Middle Left	Middle Center	Middle Right
Base:	Bottom Left	Bottom Center	Bottom Right

Note: The Left/Right settings aid placing a stair along walls.

Stair Terms:

Top is at the top of the flight of the stairs with direction of travel going down.
Landing is the intermediate platform, the first segment defines the starting (base) stair segment, in a direction of travel to down from the landing and the second segment defines the ending (top) stair segment in a direction of travel of up from the landing.
Base is the bottom of the stairs with the direction of travel going up.

Note: Landing alignments are enabled for stairs with landing configuration.

Placement - Stairs Configuration

Sets one of the predefined stair configurations. The Stairs tool provides a list of common industry standard stair configurations for placement. Dynamic Placement allows you to define unique stair configurations through precise placement of stair and landing segments.

Icon	Stair Configuration	What it Does
	Straight Run	Places a floor to floor straight run of stairs by two points (start point and direction).
	Two Straight Run	Places a straight run of stairs with an intermediate landing.
	Quarter Turn (L)	Places a floor to floor quarter turn stair by three points (landing point, direction 1st run, and direction 2nd run).
	Half Turn (U)	Places a floor to floor half turn stair by three points (1st landing point, 2nd landing point, and direction).
	Two Quarter Turn	Places a floor to floor two quarter turn stair by three points (1st landing point, 2nd landing point, and direction).
	Three Quarter Turn	Places a floor to floor three quarter turn stair by three points (1st landing point, 2nd landing point, and 3rd landing point).

The Preview pan on the Place dialog shows the recently selected configuration.

Height By

Sets the method for defining the height of a flight of stairs to one of the two options;

Height (Fixed) – Defines absolute height for a single flight of the stair assembly.
Floor Constrained – Uses the floor definitions to determine the height of the stair. The floor to floor distance of the currently active floor is taken as stair height.
Tip: For Floor Constrained height method you must first select an activate floor in floor selector.

Offsets

Top Offset - Sets an additional distance from the ceiling. This is applicable to stairs with top alignment.
For fixed height stairs, Top Offset is applicable to stairs with Left alignment.
Base Offset - Sets the distance from the floor to the stair base point. This is applicable to stairs with base or landing alignment.

Note: For Fixed Height stairs, depending upon the stair alignment, one of the above "Offset" options could be set. Whereas, for height by Floor Constraints stairs, both "Offset" properties are enabled. For example, for an active floor height of 15', setting both the top and base offsets to 1' each, results in a stair height of 13.

Setting	Description
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. (Load Stair Settings) - Opens the Stair Construction Settings which is used to set the shape, size, placement, and appearance of all elements and components that are contained in the railing assembly. 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: 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.
Stair Dimensions	Stair Height - Sets the height of the stair assembly. This is the same value set through the Stair Construction Settings dialog for the fixed height option. For floor constrained height, it displays the height of the stair assembly. In this case the floor definition controls the actual height. It is set as an absolute height relative to the active floor. The stair height property is used to quickly alter the height of the stairs in a model should the design change. When a change in the stair height is applied, the stair assembly adjusts the number of treads in the last flight. Rather, it restricts the height by keeping at least two treads in the last flight. When reducing the height of a multi-run stair, the landing in the last flight needs to be manipulated to keep it safe within the desired height. Stair Actual Slope - Displays the actual height of a riser arrived from the stair calculation. It is highly dependent on the Riser Target Height defined in the Riser tab.
Stair Parameters	Stair Width - Sets the width of the stair. This is the value set through the Stair Construction Settings dialog. You can alter the stair width to suite the design by entering a new value here or via the heads-up display. The value initializes with the active DataGroup catalog instance definition for width. Manually entered values are not saved to the catalog’s instance definition. A list of the most recently used widths are available through MRU to save previous entries. Stair Part Definition - Sets the non-monolithic stair family and part definition pair through the popped up pull down menus. Family and part assignment can be done for straight/slanted panels as well as for planar and parametric profile risers. The value set through the Part option overrides the native definitions of the family part, if any in the profile. Fire Exit - When on, applies the Fire Exit property. Place of Refuge - When on, classifies the stair to be used as place of refuge or as a shelter.
Identification	Lists identification properties for the active catalog item type.
Thermal Transmittance	Lists the thermal properties to apply to the active catalog item.
Accessibility	Lists handicap accessible and non-skid surface properties that can be applied to the stair.
Construction Phase	Lists design and construction phase properties for walls such as New Construction, Future Construction, and Items to be Moved.
IFC Override	Lists IFC properties not automatically mapped to DataGroup System properties that can be manipulated for export.
Classification	Building Classification Systems are supported by the DataGroup System. MasterFormat, OmniClass, and UniFormat property values can be associated with any Building element. Click the Value cell to open the Classification System selection combo box. The combo box is populated with selected classification system property values. It can be resized by clicking on the combo box's bottom right corner. Search for properties by name. Search results are displayed in the classifications hierarchy. Double click a property to select it. This action also closes the selection menu. The selected property displays in the selected classification system property value (on the Properties list).
