The task panel appears in the Tasks tab of the combo view, one of the important panels of the interface. It is a customizable space that is able to contain any type of graphical widget like collapsible sub-windows, tables, input fields, checkboxes, spinboxes, selector boxes, text boxes, buttons, labels, images, and other elements, depending on the currently active workbench, and the currently active tool.

A task panel normally opens when a tool that requires user input is activated, either by pressing a toolbar button or double clicking on an object. If the tool doesn't need user input, it will produce its result or terminate, but won't display a task panel.
The user input may be anything such as text, 3D point coordinates, elements from a list, faces from a shape, or options to modify the way the tool operates.

There are many commands that require selection of shapes or objects present in the document; for such cases the task panel will wait for the user to select the appropriate objects from the tree view or the 3D view.

The task panel is usually closed by clicking an or a button, or pressing the key on the keyboard to abort the command.
Task panel that opens when editing an Arch Component. The panel waits for the user to select objects that can be added or subtracted from the component.

The user is responsible for properly terminating or aborting the active command before starting a different task; leaving a task running may produce errors when trying to launch other tools.
