Organizing Modeler panes
When you first start Modeler or after you have reset the layout, all the Modeler panes are shown:
• The Packages, Parts, Diagrams, Relationships and Dictionary panes are grouped together in the top left of Modeler. These panes contain browsers that allow you to find items and diagrams in the model.
• The Contents, Results, Results 2, Output and Diagram Thumbnail panes are grouped together in the bottom left of Modeler. The Contents, Results, Results 2 panes can list items and diagrams; the Output pane can display text output from add-ins and Modeler processes; and the Diagram Thumbnail pane allows you to pan, zoom in and zoom out of the active diagram.
• The Properties pane (Property Pages) is shown in the bottom right of Modeler. The Property Pages show the properties of a selected item or diagram.
The easiest way to learn how to organize panes is to read this topic and experiment with the panes in Modeler. The organization of Modeler panes is saved for each model you work with.
A Modeler pane can be by itself (as the Property Pages pane is by default) or part of a group of panes. A group of panes can be organized collectively as if a single pane.
Opening and closing panes
You can close Modeler panes you are not using, so that there is less clutter in the Modeler window:
• To close a pane, click its 
Close button, or right-click the pane's title bar or tab, and then click Close.
Close button, or right-click the pane's title bar or tab, and then click Close.• To open a pane, click on the pane's tab, or on the > ribbon tab, click the appropriate command.
Resizing panes
You can resize a pane or group of panes by dragging its borders to the required position.
Auto hiding panes
You can free up space within the Modeler window by auto hiding panes and groups of panes. When you auto hide a pane or group of panes, a tab for the pane (or a tab for each pane in a group of panes) appears on the edge of the Modeler window, depending on which edge the pane is docked to. When you hover the mouse pointer over the pane's tab or click the pane's tab, the pane is shown so that you can work with it. When you click elsewhere in Modeler, Modeler hides the pane.
Using auto hide is a good way of maximizing the area available for diagrams without closing panes.
To auto hide a pane or group of panes, right-click the pane's title bar or tab, and then click AutoHide.

Moving a pane to docked position
By default, Modeler panes and groups of panes are docked. When docked, a pane or group of panes is part of the Modeler window - when you move or resize the Modeler window, the docked panes and groups of panes are moved or resized accordingly.
To move a pane to another a position, drag the pane's title bar or tab to an arrow type docking pane sticker.
When you drag a pane, 'docking pane stickers' appear on the Modeler window.
an arrow type docking pane stickerWhen you hover the mouse pointer over a docking page sticker, a shaded area indicates where the pane will be docked in the Modeler window:
• A docking pane sticker at the edge of the Modeler window, results in the pane taking up a space along the length of that Modeler window edge.
• A docking pane sticker within a Modeler pane, results in the pane sharing space within the space taken up by that pane.
Moving a pane to a group of panes
You can move a pane to a group of panes, or you can create a group of panes by moving a pane to another pane.
To move a pane to another pane or group of panes, drag the pane's title bar or tab to the central docking pane sticker that is displayed for the required pane or group of panes.

Reordering panes within a group of panes
You can change the order of panes within a group of panes by dragging a pane's tab to a different position within the group.
Moving a pane to an undocked position
When undocked, a pane or group of panes is independent of the Modeler window - when you move or resize the Modeler window, undocked panes and groups of panes do not change size or position. An undocked pane or group of panes can be positioned outside of the Modeler window.
To move a pane to an undocked position, drag the pane's title bar or tab to free space, that is, not to a docking pane sticker. Alternatively, double-click the pane's title bar or tab.
To move an undocked pane to its previously docked position, double-click the pane's title bar.
Note that when a pane is undocked, you can make that pane floating so that you can move it around without the docking pane stickers appearing. To make a pane float, right-click the pane's title bar or tab, and then click Floating.
