Displays and hides the Workspace Explorer window. The Workspace Explorer displays the contents of the workspace in a classification hierarchy that reflects the various relationships defined for the design objects. The content represents the current objects loaded from the database into the active workspace.
System tab
Displays all the objects in the workspace according to the hierarchy of the system. Usually, the model is the first system and subordinate systems can include anything that is in your workspace definition, such as piping or equipment. You can change the owning object for a System object by selecting More in the System box on the ribbon that appears when you select an object. You can create a new system in the Workspace Explorer by right-clicking an existing system on the System tab.
Assembly tab
Displays all the objects in the workspace, grouped by assemblies.
Space tab
Displays all the volumes in the workspace.
Work Breakdown Structure (WBS) tab
Shows the objects in the workspace grouped by project, contract, area, and so forth.
Analysis tab
Displays the structural analysis models in the workspace. An analysis model is a non-graphical and logical grouping of member systems that can be sent to a third- party analysis and design solver package.
Reference tab
Displays the files attached in the workspace. This tab appears after you attach a file by clicking Insert > File. For more information, see Insert File.
Reference 3D tab
Displays hierarchy of Reference 3D projects and files attached as well as their objects in the workspace. This tab appears after administrator attached a R3D Model by using New R3D Reference command in Project Management.
Point Cloud tab
Displays the available point cloud objects in the workspace. This tab appears only if there are any registered point cloud data sets in the Model. You can also suppress the selected point cloud objects using the Suppress Point Cloud option. You can access this option by right-clicking a point cloud model in the Workspace Explorer and selecting Suppress Point Cloud on the shortcut menu. For more information about suppressing and modifying the point cloud objects, refer the Suppress Point Cloud section in the CloudWorx for Smart 3D User's Guide.
Drawings tab
Displays the drawings related to the workspace. For more information, see Drawing Console.
The Workspace Explorer view allows you to identify or select objects or sets of objects by name. Icons appear at the left of the window objects to indicate the type of the object. For example, a file folder icon represents a system, an equipment icon represents equipment, an I-beam icon represents a structural system, and so forth. Point to objects in the Workspace Explorer to highlight them, and click objects to select them. If you hide objects using the Tools > Hide command, the object names appear in italics. For more information on hiding objects, see Hide.
If you pause the pointer over an object in the Workspace Explorer, the object is highlighted with the highlight color in the graphic view and in the Workspace Explorer. If you pause the pointer over an object in a graphic view or in the To Do List dialog box, the object is highlighted with the highlight color in the Workspace Explorer. However, if you select certain objects such as features in a graphic view, they do not highlight in the Workspace Explorer (because features do not appear in the Workspace Explorer). Foundation ports also do not appear in the Workspace Explorer, but nozzles do.
If you select an object in the Workspace Explorer, it appears highlighted with the select color in the graphic view. However, if you are in the Drawings tab and you select a drawing, no objects in the drawing highlight in the graphic view. If you select an object in a graphic view, it highlights in the Workspace Explorer. The Workspace Explorer automatically scrolls when objects highlight if the object is outside the Workspace Explorer window. Automatic scroll is not available if the object is already in the Workspace Explorer window.
If you select a set of objects, but the set contains objects you do not want, press CTRL and click to cancel the selection of unwanted objects. For multiple selections, press CTRL+SHIFT. If you select a parent object and then press SHIFT and click the last listed child of the parent, you get the parent and immediate child objects belonging of the parent. A right-click allows you to select the parent and all nested children of the parent.
If you are currently working in a command, you can select multiple objects in the Workspace Explorer without holding CTRL or SHIFT.
You can widen or narrow the Workspace Explorer window for better viewing. Lock the Workspace Explorer’s node expansion by selecting the Lock Tree 
option.
In the Workspace Explorer, you can select or type a name in the box at the top of the view. The list displays the last 15 objects you selected that satisfy the current select filter. Also, you can use the wildcard * (asterisk character) when typing the name in the box at the top of the view. If you are in the Drawings tab, the search results display one at a time. Press ENTER to navigate through these search results.
-
You can complete basic command functions, such as copy, paste, and delete in the Workspace Explorer window. Drag and drop is not supported by the Workspace Explorer.
-
If you select an object in the Workspace Explorer that another user has deleted, the following message appears in the graphic view: Removing the object from working set because it was not located in the database. Please refresh data.
-
The list of child objects under the Assembly hierarchy root appear sorted when a workspace is defined, but can become unsorted during modeling. To sort this list, use the Refresh Workspace Explorer command from the Workspace Explorer shortcut menu. To display this menu, right-click in the Workspace Explorer white space area. This behavior applies only to child objects of the Assembly hierarchy root. All other hierarchies and nodes in the Assembly hierarchy are not affected by this change.
