Elements of the Environment
Altium Designer is unique in its ability to support all aspects of electronic design, from capture to generation of PCB manufacturing output. It does this in a single software application, through the support of the underlying X2 integration platform. The platform supports all of the standard user-interface elements, such as menus and toolbars (also called resources), with each editor plugging in its own specific set of resources and commands. See the below section for descriptions, access, etc., to Altium Designer's environment elements.
The following sections describe some of the main elements of the design space highlighted in the image above.
Preferences
Preferences dialogs are a central location in which you can set up global system settings across different functional areas of the software. These preferences apply across projects and relevant documents. The various dialogs are accessed by clicking 
at the top right of the design space. Use 
on the left side of the dialog to open the selections for the required area then choose the desired title to open that specific preference page.
Active Workspace Control

icon will be displayed at the top-right of the design space. Click the icon to show a pop-up message where the issue is described and recommendations for its resolution are suggested.
Panels
Panels are essential elements of the Altium Designer environment. Whether specific to a particular document editor, or used on a more global, system-wide level, they present information and controls that aid productivity and allow you to design more efficiently. For example, the PCB panel can be used to browse by Components or Nets. When Altium Designer is first started, the Projects panel will already be open and pinned/docked on the left side of the design space. To open other panels, click the Panels button at the bottom right of the design space then select the desired panel. Each editor has panels specific to that editor.

Two panels of interest that are widely used when working in virtually every editor in Altium Designer are the Properties and Messages panel.
Properties Panel
The Interactive Properties panel provides universal editing access to the properties of documents and objects available in each design editor. The panel dynamically determines its content (or, in other words, changes its mode) based on the document or object that is currently selected and presents specific properties and settings that relate to that document/object. The Properties panel also supports editing the properties of multiple selected objects.
The Properties panel in its Components mode. This mode is active when a component is selected in a schematic sheet.
Messages Panel
Whether validating a project, running a design rule check for the active PCB document, performing a mixed-signal simulation, or using any of the other message-enabled features of the software, the Messages panel provides an intelligent way of listing any warnings and/or errors that may be present, as well as any status information. The panel supports cross-probing from the selected message in the panel to the object responsible for the message in the associated document.
The Messages panel
Active Bar
The Active Bar gives you quick access to frequently used functions that are also found in the main menus. You can hover over an icon to view a pop-up of the icon's description. To use the icon displayed, click on it. For placement icons, the object will appear on the cursor, allowing you to drag the object to the required location. When a white triangle is displayed at the bottom right of an icon, there is a group of other icons available. Click and hold the cursor over that icon to display a list of additional icons available then select the desired command/icon. The most recently used icon is displayed for that group.

Hover the cursor over the indicator for information about which resource(s) are exceeding associated levels of consumption. Note that the color of the indicator changes to highlight the level of resource consumption.
A warning indicator appears when Altium Designer's resource consumption becomes high, and changes color to indicate when action is required.
The following resources are monitored:
- Memory used by Altium Designer
- Count of allocated GDI handles
- Percentage of allocated global and session atoms
The resource monitor triggers and displays a warning indicator when any of the above resources reach the following levels:
- < 60% normal level (no resource indicator is displayed)
- 61% to 75% is considered a high level, indicated by a yellow indicator
- 76% to 90% is considered a very high level, indicated by an orange indicator. In addition, the message indicates that a restart of Altium Designer is advisable.
- > 90% is considered a critical level, indicated by a red indicator. In addition, the message indicates that a restart of Altium Designer is advisable.
