	Point Clouds	Used to manage the display of one or more point clouds in a DGN file view.
	Reality Mesh	Opens the Reality Mesh Attachments dialog, which is used to attach and manipulate reality meshes.
Models		Used to create, manage, and switch between models in the open DGN file.

Level Manager		Used to control level display and level symbology for the open DGN/DWG file and attached references.
Properties		Used to review or modify the properties of an element(s), such as its geometry.
More	Keyin	Used to browse, construct, and enter key-ins.
	Toggle AccuDraw	Turns on/off AccuDraw, and the display of the AccuDraw Window, which is used to facilitate data point entry.
	Auxiliary Coordinates	Used to create, copy, delete, or import an Auxiliary Coordinate System (ACS) and to select ACS tools.
	Saved Views	Used to create, update, apply, import, and delete saved views and edit properties of saved views. Saving a view allows you to quickly apply a view with specific attributes.
	Cells	Used to attach cell libraries and activate different types of cells, if one is attached.
	Markups	Used to view markups made in an overlay file in Bentley Navigator. A markup can be annotation text, freehand redlining, pen and area highlighting.
	Details	Used to display information related to what is selected in any of the tabs of the Explorer dialog.
	Window List	Used to display information related to what is selected in any of the tabs of the Explorer dialog.

Table 2. Selection group
Tool name		Description	Shortcut
Element Selection		Used to select and deselect elements for modification or manipulation. The set of selected elements is called the selection set.
Select All		Selects all elements in the design.	Ctrl+A
Select None		Deselects all elements in the design.
Fence Tools	Place Fence	Used to place a fence.
Fence Tools	Modify Fence	Used to move a fence or modify one of its vertices.
Manipulate Fence Contents		Used to move, copy, rotate, mirror, scale, or stretch fence contents, which are defined by a fence and (except for stretching) the Fence (Selection) Mode.
Delete Fence Contents		Used to delete the fence contents, which are defined by a fence and the Fence (Selection) Mode, which determines what constitutes the contents of a fence.
Drop Fence Contents		Used to break up the contents in a fence into their components.
Save Fence Contents		Used to copy or move the contents of the active fence to a new DGN or DWG file.
Named Boundaries		Used to manage named boundaries and named boundary groups.
Lock		Locks selected elements. The attributes and location of a locked element cannot be changed. Locking is useful for preventing accidental element manipulation. If you try to manipulate a locked element, OpenBridge Modeler beeps to alert you that the element is locked.	Ctrl+L
Unlock		Unlocks selected locked elements. Each unlocked element can be manipulated.	Ctrl+M
Bring to Front		Brings the selected element to the front of the view display.	Ctrl+L
Cut		Used to cut selected elements to clipboard.	Ctrl+X
Copy		Used to copy selected elements to clipboard.	Ctrl+C
Paste	Paste	Used to paste elements from clipboard.	Ctrl+V
Paste	Paste Special	Used to select the data type and open the Paste OLE dialog where a special display format can be applied to the contents of the Clipboard.

Table 3. Bridge Setup group
Tool name		Description
Import	Geometry	Used to import external civil data such as road alignment.
Import	Terrain	Used to import external terrain data into your OpenBridge Modeler design.
Bridge Wizard		Used to parametrically generate a 3D bridge model with minimal input.
Add Bridge		Used to add a new bridge to the OpenBridge Modeler design.
Add Unit		Used to add a new bridge unit. The new unit will be the active unit.
Alignment		Used to select an alignment in your project as the active alignment for the active bridge unit.
Move		Used to specify a new station along the current bridge alignment for the start of the active bridge.
Terrain		Used to select a terrain model as the current active terrain.
Add Multi-Units		Used to add mutliple bridge units to the current bridge.

Table 4. SupportLine group
Tool name		Description
Place	Place Middle Point	Used to place a supportline by the supportline's midpoint at a specified station.
	Place Parallel	Used to place a supportline parallel to an existing supportline.
	Place Multi	Used to place multiple supportlines which can have similar values or individually edited values.
Move		Used to move or rotate an existing supportline to the position or orientation a previously placed target line.
Modify		Opens the Modify Multi Supportlines dialog, which is used to modify multiple supportlines in the active unit.

Table 5. Superstructure group
Tool name		Description
Place Deck		Used to place a deck template over supportlines.
Place Advanced Deck		Used to place advanced decks for cast-in-place box bridges.
Beam Layout		Used to layout beam lines for spans between supportlines.
Place Beam		Used to select a beam definition for a beam layout.
