A Fresh User Interface (New Feature Summary)

Altium Designer 18.0 delivers productivity improvements through:

• Substantial performance improvements - computationally intensive tasks, such as an ActiveRoute of 100 nets and analyzing a complex ground net, are significantly faster. 
• Enhanced responsiveness allows greater fluidity when rotating and zooming your 3D PCB. 
• Comprehensive review of the user interface and the experience of using that interface.

Altium Designer 18.0 also presents an entirely new look and feel that will enhance your board design experience. From the color scheme of the main editors, to the new and more comprehensive panels, to a quicker route to your Preferences and managed content server, this updated version of Altium Designer gives you more streamlined ways to work as you build your designs.

A few of the changes include:

• A new color scheme. Altium Designer now presents with a dark background, with lighter text. Studies have shown that, while a text-oriented interface generally works best with dark text on a light background, an image-intensive interface is better for the eyes with light content on a dark background.
• The new Properties panel removes the need for object dialogs in editors and therefore makes placing and editing objects much quicker and easier. The new panel also brings in parent and child properties into one streamlined access point.
• A new Active Bar provides placement controls for PCB, schematic, Draftsman, and library documents at your fingertips. 
• Panels and Preferences have been streamlined by eliminating some elements that are not often utilized.
• The Vaults panel has been retitled the Explorer panel.

The purpose of this document is to provide an overview of the key user interface changes found in Altium Designer 18.0. Detailed information regarding new features and functionality in this release, as well as enhancements and improvements to existing features, will be covered in other documents. This document discusses the improved user interface and the benefits it brings. Read on to explore the key changes to the software's appearance - changes that collectively reinvigorate the design workspace and enhance your design productivity.

We have changed the overall color theme of Altium Designer to a charcoal background. This new theme allows for a more defined workspace. Panels and some dialogs have been given the new color theme as well. 

The new Altium Designer workspace

       The new Altium Designer panels color scheme (Projects panel and PCB List panel shown as examples)

The new color scheme has been applied to some dialogs (Project Options shown as an example).

The new Properties panel contains information and controls that pertain to the item currently selected in the workspace. If nothing is selected in the current workspace, when accessed from a PCB document, the panel presents board options; when accessed from a schematic document, document options are presented; library options are presented when accessed from a library document; and multi-board options are presented when accessed from a multi-board document. The panel also presents the currently active BOM document (*.BomDoc). This allows you to change general document options quickly and on-the-fly. The panel also appears when placing objects (arc, text string, wire, etc.,) on the workspace. You can use the Properties panel to configure objects before placement. The Selection Filter section allows control over what you can and cannot select in the workspace.

Placing Items

When placing an item using the Place command or the new Active Bar, you can click the Tab key after making your selection of the item to be placed to open the Properties panel in order to make any desired updates before placement. When you are ready to leave "placement mode", click the "Pause" symbol that appears on the workspace to leave placement mode.

The Search function at the top of the Properties panel (highlighted in the following image) allows you to search within the panel for desired items.

You can use the two buttons at the top-right of the Properties panel to control the contents of the panel. 

Click the  button (button on the left) to include in the Properties panel all types of objects from any open documents of the same project.

Click the  button (button on the right) to include in the Properties panel all types of objects from the current document only.

View Configuration Panel

The View Configuration panel allows you to edit and control the layers of the PCB and their associated colors and settings, and configure visibility, 3D settings, and masking. The panel also improves usability of more complex behaviors, such as layer pairs.

The View Configuration panel includes controls that allow you to configure the layers of a PCB document.

The Search function at the top of the panel allows you to search within the panel for desired items.

Enabling/Disabling Layers

You can enable or disable one layer, multiple layers, or all layers by toggling controls in each layer group as shown in the following images.  

Use the highlighted controls to enable or disable layer groups. Component Layers are shown as all enabled in this example.

Use the top control to toggle the enable/disable for the entire layer as shown in the following image.

Clicking the control highlighted will toggle the control for the entire group. All items are disabled for Component Layers in the above image.

You also can enable or disable individual items in each group by toggling the control as shown in the following image.

The highlighted individual items in the Component Layers group have been disabled.
