Combo view

Introduction
The combo view is one of the main panels in the FreeCAD interface. It is located on the left side of the screen by default. It is composed of two sections, the:
 * Upper section which contains two tabs: the tab and  tab
 * Lower sectionl shows the Property editor. It alsobcontains two tabs: the and  properties. Note: The Property editor is only shown when the  tab is active, that is, when the tree view is visible.

Background
Originally the upper part (tree view) was separate from the lower part (property editor) but then they were combined, and thus the "combo" view was created.

Disabling Combo view
To use these views by themselves use the parameter editor. Create the following subgroups if they don't exist

then add the parameter of type, and set it to.

Then activate the view using the menu, or.

Upper section
The tab shows the tree view, which is a representation of the document's content, including 2D and 3D geometry with their parametric history, but also supporting objects that contain data saved in the document.

The tab shows the task panel, which will show different actions depending on the active workbench, and the active tool.



Lower section
The lower part of the combo view shows the property editor, which displays two tabs for and  properties. The property editor is only shown when the tab is active, that is, when the tree view is visible.

The tab shows visualization properties of the objects, which only affect their appearance in the 3D view.

The tab shows the parametric properties of the objects, which determine how the geometrical shapes are defined.
