Model browser

At any time you can use the model browser to see what objects you have in your model. To display the model browser, use the model browser button or the Model | Model browser menu item or use the keyboard shortcuts (F6 to open the model browser).

Figure: Model browser

The model browser consists of a list of all the objects in the model, arranged into categories according to object type. Several symbols are used in the list of objects:

Categories can be opened, to show their contents, or closed, to simplify viewing a complex model.
Objects. Use double click to view or edit the object's data.
Locked. These objects cannot be dragged by the mouse in the 3D view.

You can navigate the list and select the object required by clicking with the mouse, or with the arrow keys. If the list is longer than the window then you can either enlarge the window or use the scroll bar.

Note: You can act (e.g. delete, copy, hide, show, locate) on multiple objects at once by selecting all the objects you want to apply the action. To select more than one object, use the standard Windows key presses CTRL+click to add to a selection and SHIFT+click to extend a selection. Or, if all the the objects are in a browser group, simply select the group.

Model browser facilities

The model browser menus, and its popup menu, provide the following model management facilities.


The Library menu facilities allow you to open a second data file. You can then import objects from that second file into the current model. You can also import using drag and drop with the mouse.


Add a new object to the model.

View by groups

When checked the browser shows the groups view, otherwise the types view is shown.


Open the selected object's data form. This action can also be invoked by double-clicking an item, or by selecting it and pressing ENTER.

Move selected objects

Opens the move selected objects wizard.


Rename the selected object.


Finds and highlights the selected object in any open 3D view windows. This is useful in complex models where many objects are on the 3D view. The highlighting method is determined by the locate object method preference.


Compares data for the two selected objects. The objects can be simple OrcaFlex objects (e.g. vessels, lines etc.) or browser groups. The compare data configuration is used to perform the comparison.


Lock or unlock the selected object.


Control whether or not the selected object is drawn on 3D views.

Report mooring stiffness

Calculates and reports the mooring stiffness for the selected vessels.


Shows the object properties form for the selected object. If multiple objects are selected then compound object properties are reported.

Show all objects/hide all objects

Control whether or not all objects are, collectively, drawn on 3D views.

Expand all/collapse all

Expands or collapses all top level containers in the current browser view.


Cut or copy the selected object to the clipboard.


Paste an object from the clipboard into the model.


Delete the selected object from the model.

Floating, dock left, dock right

Determines whether the model browser is a separate, floating, top-level window or is docked inside the main OrcaFlex window.


You can use drag and drop with the mouse to reorder objects in the model. This is useful if you are working on the static position of one particular line – you can drag it up to the top of the list of lines, so that it will be tackled first when OrcaFlex does the static analysis.

Switch to main window

The browser's Window menu (only visible for a floating browser) enables you to switch focus to the main form without closing the browser window. A corresponding command on the main form's Window menu switches focus back. The keyboard shortcut for this, SHIFT+F6, is available regardless of whether the browser is floating or docked.
