PCB Environment Setup

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

A logical step after creating and checking the schematic document is creating and designing the PCB. Use the File » New » PCB command to create a new PCB document. It is a good idea to configure the PCB by defining the origin, units, grid size, as well as the color display and visibility of the required layers.

Many aspects of the PCB environment setup are configured through the Properties panel in its Board mode described below. To learn more about other features for the configuration of the PCB environment, refer to the following pages:

  • Colors & Visibility Control – the PCB editor can display the PCB document in 2D or 3D modes with definitions for layers, 3D colors, visibility and other items, known as view configurations, available from the View Configuration panel.
  • Working with the Cursor-Snap System – the PCB editor is a grid-based design environment - design objects are placed on what is referred to as the placement, or snap grid. As well as the snap grid, the software includes a number of additional snap features, designed to help you accurately position and align design objects. Together, these features are referred to as the Unified Cursor-Snap System.
  • Working with Mechanical Layers – even the simplest board needs design detail beyond the tracks and pads that implement the circuit. It might be the component courtyards or it might be the 3D component models. In Altium NEXUS, this type of additional information is detailed on Mechanical Layers.
  • Your View of the PCB – modern PCBs are multi-layer entities that require their clear representation in the PCB editor design space. Altium NEXUS features a comprehensive set of tools facilitating the display of the objects, layers, and nets that you need right now, in both 2D and 3D modes.
  • PCB Panel – the PCB panel allows you to browse the current PCB design using a range of filter modes to determine which object types or design elements are listed, highlighted, or selected.

Properties Panel

The Properties panel in its Board mode (active when no design object is currently selected in the PCB editor design space) contains options and controls for the basic configuration of the current PCB document.

The following collapsible sections contain information about the options and controls available under the panel's General tab:

The following collapsible section contains information about the options and controls available under the panel's Parameter tab:

The panel's Health Check tab provides an interface to the PCB Health Check Monitor. To learn more about this functionality, see PCB Health Check Monitor.

When a design object is selected, the panel will present options specific to that object type. The following table lists the object types available for placement within a PCB document – click a link to access the properties page for that object.

Although Tracks and Lines are actually the same object, the difference is how the software behaves during their placement, which is why there are different commands.

After launching the Place » Line command, the cursor will change to a cross-hair and the editor will enter line placement mode. Placement is made by performing the following actions:

  1. Click to define the starting position of the line.
  2. Move the cursor to set the length and angle the line then click again to complete placement.
  3. Continue placing further lines, or right-click or press Esc to exit the placement mode.
