Creating a New Project

Project Types

Altium Designer supports various project types, including:

1. PCB Project
2. Schematic Project
3. FPGA Project
4. Embedded Project

Setting Up a PCB Project

1. Click on “File” > “New” > “Project” to open the New Project wizard.
2. Select “PCB Project” and choose a project template (e.g., “PCB Project – 2 Layer”).
3. Specify the project name, location, and version control settings (if applicable).
4. Click “OK” to create the project.

Schematic Design

Creating a New Schematic

1. In the Projects panel, right-click on the project name and select “Add New” > “Schematic”.
2. Enter a name for the schematic and click “OK”.

Adding Components

1. Open the Libraries panel and search for the desired component.
2. Drag and drop the component onto the schematic sheet.
3. Repeat the process for all required components.

Wiring Components

1. Select the “Place Wire” tool from the toolbar or press “P” on the keyboard.
2. Click on the first pin to start the wire and click on the second pin to end it.
3. Use the “Place Junction” tool or press “J” to create junctions where wires intersect.

Applying Design Rules

1. Open the “Design” menu and select “Rules”.
2. Create or modify design rules for the schematic, such as component placement, routing, and electrical constraints.
3. Validate the schematic against the design rules to identify any violations.

PCB Layout

Creating a PCB from a Schematic

1. In the Projects panel, right-click on the schematic and select “Create PCB from Schematic”.
2. Configure the layer stack, board shape, and other settings in the PCB Wizard.
3. Click “Finish” to generate the PCB layout.

Placing Components

1. Use the “Move” tool or press “M” to select and move components on the PCB.
2. Rotate and flip components as needed using the “Rotate” and “Flip” commands.
3. Arrange components to optimize space and minimize signal paths.

Routing Traces

1. Select the “Interactive Routing” tool from the toolbar or press “Shift+R”.
2. Click on a pad to start the trace and click on the destination pad to end it.
3. Adjust trace width, layer, and other properties using the Properties panel.

Applying Design Rules

1. Open the “Design” menu and select “Rules”.
2. Create or modify design rules for the PCB, such as clearance, trace width, and via size.
3. Run the Design Rule Check (DRC) to verify that the PCB layout complies with the specified rules.

3D Visualization

Generating a 3D Model

1. Open the “View” menu and select “3D Layout Mode”.
2. Altium Designer will generate a 3D model of the PCB based on the component models and board shape.
3. Use the navigation controls to zoom, pan, and rotate the 3D view.

Customizing the 3D View

1. Adjust the display settings, such as color scheme and transparency, in the “View Configuration” panel.
2. Apply realistic textures and finishes to the components and board surface.
3. Export the 3D model in various formats for visualization or manufacturing purposes.

Library Management

Creating Custom Components

1. Open the “File” menu and select “New” > “Library”.
2. Choose the library type (e.g., Schematic Library, PCB Library) and specify the library name and location.
3. Use the symbol and footprint editors to create custom components or modify existing ones.

Managing Libraries

1. Use the Libraries panel to organize and manage your component libraries.
2. Create library folders to categorize components by type, manufacturer, or project.
3. Share libraries with team members using Altium Vault or version control systems.

Collaboration and Version Control

Using Altium Vault

1. Set up an Altium Vault server to store and manage design data centrally.
2. Check in and check out design files to collaborate with team members and avoid conflicts.
3. Use the Vault Explorer to browse and manage design revisions and releases.
