Chapter 1: Getting Started with FreeCAD

Understanding FreeCAD and Its Capabilities

FreeCAD excels at parametric modeling, where designs are built through a history of operations that can be modified at any point. This capability makes it particularly suitable for engineering and product design, where specifications often change during development. Unlike some CAD programs that focus narrowly on specific industries, FreeCAD's workbench architecture supports mechanical design, architecture, finite element analysis, CAM, and more within a single application.

The software operates on a feature-based modeling paradigm. You create sketches that define 2D profiles, then apply operations like extrusion or revolution to generate 3D geometry. These features remain editable, and relationships between features are maintained through the parametric system. This approach mirrors professional CAD workflows found in commercial software, making skills learned in FreeCAD transferable to other platforms.

FreeCAD handles both bottom-up and top-down design methodologies. In bottom-up design, you create individual parts and assemble them. Top-down design starts with the overall assembly context and derives parts from it. The software supports both approaches, giving you flexibility in how you structure your projects. This versatility makes FreeCAD suitable for everything from simple mechanical parts to complex assemblies with hundreds of components.

System Requirements

Before installing FreeCAD, verify that your computer meets the minimum requirements. For Windows systems, you need Windows 7 or later, though Windows 10 or 11 is recommended for best performance. The software requires at least 4GB of RAM, but 8GB or more significantly improves performance when working with complex models. A multi-core processor enhances responsiveness, particularly during computationally intensive operations like meshing or rendering.

Graphics capabilities matter more than many users realize. While FreeCAD will run with basic graphics, a dedicated GPU with OpenGL 3.2 support or higher provides smoother viewport navigation and better visual quality. Modern integrated graphics generally meet this requirement, but discrete graphics cards deliver superior performance. Ensure your graphics drivers are up to date, as outdated drivers can cause display issues or crashes.

For macOS users, version 10.12 Sierra or later is required, with newer versions offering better stability. Linux users have the widest range of options, with FreeCAD available through most distribution repositories. The same hardware recommendations apply across all platforms. Disk space requirements are modest, with the application itself taking under 1GB, though project files can grow substantially depending on complexity.

Downloading and Installing FreeCAD

The official FreeCAD website at freecad.org provides downloads for all supported platforms. Navigate to the download section and select the version appropriate for your operating system. For Windows, you'll typically choose between a 64-bit installer or a portable version. The installer is recommended for most users as it handles file associations and shortcuts automatically.

Download the latest stable release of FreeCAD 1.0 rather than development versions, which may contain experimental features and reduced stability. The download size is approximately 300-500MB depending on your platform. Once downloaded, verify the file isn't corrupted by checking that the file size matches what's listed on the website.

On Windows, run the installer with administrator privileges. Accept the license agreement, which is LGPL for the core application. Choose the installation directory, though the default location works well for most users. The installer will ask about creating desktop shortcuts and file associations. Enable file associations if you want FreeCAD files to open automatically when double-clicked. The installation process typically completes in under five minutes.

For macOS, the download comes as a DMG file. Open it and drag the FreeCAD application to your Applications folder. The first time you launch FreeCAD, macOS may display a security warning because it's downloaded software. Right-click the application and select Open to bypass this warning. Subsequent launches won't require this step.

Linux users can install FreeCAD through their distribution's package manager. For Ubuntu or Debian-based systems, use the command line with appropriate package management tools, or install through the software center GUI. AppImage versions are also available, providing a portable option that runs on most Linux distributions without installation. Make the AppImage executable and run it directly.

First Launch and Initial Setup

When you first launch FreeCAD, the Start page appears, providing quick access to recent files, example projects, and learning resources. Take a moment to familiarize yourself with this interface. The Start page includes links to documentation, forum discussions, and tutorial videos. These resources complement this manual and provide additional perspectives on FreeCAD workflows.

Before diving into modeling, configure some basic preferences. Access preferences through the Edit menu on Windows and Linux, or the FreeCAD menu on macOS. The preferences dialog contains numerous settings organized by category. For now, focus on a few essential configurations that will improve your initial experience.

In the General section, set your preferred language if English isn't your first choice. FreeCAD supports dozens of languages, though some translations may be incomplete for newer features. Below language settings, you'll find options for the Start page behavior. You can choose whether it appears on launch or have FreeCAD open directly to a blank document.

The Display section controls visual aspects of the interface. Here you can adjust the 3D view background color. Many users prefer a gradient background for better depth perception, while others choose solid colors. Enable anti-aliasing if your graphics card supports it for smoother edge display. The render cache option can improve performance with complex models but uses more memory.

Under Units, set your preferred measurement system. FreeCAD supports metric and imperial units, as well as specialized systems for specific applications. Choose the system you're most comfortable with. This can be changed anytime, and FreeCAD will convert existing dimensions accordingly. The default precision settings are usually appropriate, but you can adjust them if your work requires specific decimal places.

Save your preferences and restart FreeCAD if prompted. Some settings only take effect after a restart. When FreeCAD reopens, your customizations will be active, and you're ready to begin exploring the interface in detail.

Understanding the FreeCAD Interface

The FreeCAD interface consists of several distinct areas, each serving specific purposes. Understanding this layout is fundamental to efficient work. At the top, the title bar displays the current document name and the active workbench. Below that, the menu bar provides access to all major functions through traditional dropdown menus. This menu structure changes slightly depending on which workbench is active.

The toolbar area appears below the menus. Multiple toolbars can be displayed simultaneously, providing quick access to frequently used commands. These toolbars are contextual, meaning different tools appear depending on your current workbench. You can customize which toolbars are visible through the View menu. Right-clicking in the toolbar area reveals options to show or hide specific toolbars.

The central area of the interface is the 3D view, where you'll visualize and interact with your models. This viewport supports standard 3D navigation including rotation, panning, and zooming. The view cube in the upper right corner provides quick orientation changes to standard views like front, top, and isometric. Clicking the cube faces reorients the view instantly.

On the left side, the Model tree (also called Tree view) displays the hierarchical structure of your document. Every object, feature, and operation appears here in the order created. This tree is interactive; selecting items here selects them in the 3D view, and vice versa. Right-clicking objects in the tree reveals context menus with relevant operations.

The right side of the interface contains the Properties panel, also called the Property editor. This panel displays all properties of the currently selected object. Properties are organized into sections like Data for geometric parameters and View for display settings. Values can be edited directly in this panel, providing precise control over object characteristics.

Below the 3D view, the Python console provides access to FreeCAD's scripting interface. While you won't need this immediately, it's useful for advanced operations and automation. The Report view, often tabbed with the Python console, displays system messages, warnings, and errors. Monitoring this view helps identify issues during modeling.

Customizing Your Workspace

FreeCAD's interface is highly customizable, allowing you to arrange elements to match your workflow. Panels can be moved by dragging their title bars. You can dock panels to different edges of the interface or float them as independent windows. This flexibility is particularly useful on multi-monitor setups where you might dedicate a second screen to properties or the model tree.

To reposition a panel, click and hold its title bar, then drag it to your desired location. As you drag, docking indicators appear showing where the panel will attach. Release the mouse when the indicator highlights your preferred location. Panels can be tabbed together by dragging one onto another, creating tabbed groups that save screen space.

The workbench selector, located in the toolbar area, is critical for accessing different tool sets. It appears as a dropdown menu listing all available workbenches. Switching workbenches changes the available tools and sometimes the menu structure. Frequently used workbenches can be added to the workbench toolbar for quick access without using the dropdown.

Toolbar customization allows you to create a personalized tool set. Right-click in the toolbar area and select Customize to open the customization dialog. Here you can create new toolbars, add or remove commands from existing toolbars, and rearrange buttons. If you frequently use specific commands across different workbenches, create a custom toolbar containing just those tools.

The View menu offers additional interface options. You can toggle the visibility of specific panels, enter fullscreen mode, or switch to different visual styles. The Dockable Windows submenu controls which panels are visible. If you accidentally close a panel, this menu allows you to restore it. The Toolbars submenu manages toolbar visibility.

Consider creating multiple workspace configurations for different tasks. While FreeCAD doesn't have a built-in workspace preset system, you can manually arrange the interface for specific activities. For example, configure one layout optimized for sketching with the task panel prominent, and another for assembly work emphasizing the tree view. Switching between these configurations manually becomes quick with practice.

Navigating the 3D View

Effective 3D navigation is essential for productive CAD work. FreeCAD supports multiple navigation styles to accommodate different preferences and backgrounds. The default navigation style works well for most users, but you can change it in preferences if you're accustomed to another CAD program's navigation scheme.

The primary navigation operations are rotation, panning, and zooming. With the default Gesture navigation style, hold the right mouse button and move the mouse to rotate the view around the model. Hold the middle mouse button to pan, shifting the view without rotation. Use the scroll wheel to zoom in and out. These operations become second nature with practice.

For users with a two-button mouse or trackpad, alternative methods exist. Holding Shift while right-clicking and dragging pans the view. Holding Ctrl while right-clicking and dragging zooms. These modifier key combinations provide full navigation capability even without a three-button mouse or scroll wheel.

The view menu provides additional navigation options. Standard views like Front, Top, and Right position the camera perpendicular to the corresponding planes. Isometric and Trimetric views provide angled perspectives useful for general modeling. These view commands have keyboard shortcuts worth memorizing for quick orientation changes.

The view cube in the upper right corner offers visual navigation. Clicking its faces rotates to standard orthogonal views. Clicking edges or corners provides angled views. The small arrows next to the cube rotate the view in 90-degree increments. The sphere icon below the cube resets to a home view, useful when you've lost track of model orientation.

Fit selection and fit all commands adjust the zoom level to frame selected objects or the entire model. These commands are invaluable when working with large assemblies where individual parts might be far from the origin. The keyboard shortcuts for these functions are among the most frequently used in FreeCAD.

Draw style options change how geometry appears in the viewport. Wireframe mode displays only edges, useful for complex models where surface shading obscures details. Flat lines mode shows shaded surfaces with visible edges, providing good depth perception while maintaining clarity. Hidden line mode presents a clean presentation view. Switch between these styles based on your current task.

The selection of objects in the 3D view follows standard conventions. Click an object to select it. Hold Ctrl while clicking to add objects to the selection. Hold Shift and drag to draw a selection box. The selection behavior interacts with the tree view; selecting items in either location updates the other. Double-clicking often enters edit mode for that object, though behavior varies by object type.

Essential Preferences and Settings

Beyond the initial setup preferences, several other settings significantly impact your FreeCAD experience. Revisit the preferences dialog to configure these additional options as you become more comfortable with the software. The Document section contains settings affecting how files are created and saved.

Enable automatic backup if you want FreeCAD to periodically save recovery files. This feature has saved countless hours of work after unexpected crashes or power failures. Set the backup interval based on your comfort level; every 15 minutes is reasonable for most users. Backup files are stored in a temporary directory and are automatically deleted when you close FreeCAD normally.

The mouse navigation section, found under Display preferences, allows you to choose from multiple navigation styles. If you're coming from other CAD software, select the style that matches your previous experience. Inventor, CAD, and OpenCascade styles are available among others. You can also create a custom navigation scheme if none of the presets match your preferences.

Grid settings, also in the Display section, control the reference grid displayed in sketch mode and some other contexts. Adjust grid spacing to match typical dimensions in your work. If you design small parts, a fine grid is helpful. Architectural work might need larger spacing. The snap-to-grid feature, when enabled, helps align elements to grid intersections for precision.

Part Design workbench settings deserve attention if mechanical design is your primary focus. These preferences control default behaviors for features like pads and pockets. You can set whether features automatically reverse direction, default length values, and how the system handles symmetric options. Configuring these to match your typical workflow reduces repetitive setting changes.

Sketcher preferences affect constraint behavior and display. The auto-remove redundant constraints option is generally helpful, preventing over-constrained sketches. The constraint display settings control how constraints appear visually. Some users prefer minimal visual clutter, while others want comprehensive on-screen feedback. Adjust these to match your visual preferences and working style.

For users planning to work with assemblies, investigate the available assembly workbench preferences. FreeCAD offers multiple assembly approaches through different workbenches. Each has specific settings controlling default constraint types, solver behavior, and performance options. These become relevant as you progress to assembly work in later chapters.

This chapter has established your foundation in FreeCAD, covering installation, interface understanding, and essential configuration. You're now prepared to begin actual modeling work. The next chapter will build on this foundation, introducing core concepts and fundamental operations that underpin all FreeCAD modeling activities. Take time to practice navigation and interface customization before proceeding; comfort with these basics accelerates all future learning.
