Property Editor

The Property Editor provides detailed information about the selected object or feature, including its properties, dimensions, and coordinates.

Task Panel

The Task Panel displays the available tools and commands for the selected task, making it easier to complete specific tasks and operations.

Basic Operations in FreeCAD

To get started with FreeCAD, you need to learn basic operations such as creating new objects, editing existing objects, and performing basic modeling tasks. Here are some essential steps to follow:

Creating New Objects

To create a new object, follow these steps:

1. Select the desired object type (e.g., part, assembly, or drawing) from the Task Panel.

2. Click on the “New Object” button in the Task Panel.

3. Define the object’s properties, such as its size, shape, and material.

Editing Existing Objects

To edit an existing object, follow these steps:

1. Select the object you want to edit in the 3D View.

2. Click on the “Edit” button in the Task Panel.

3. Modify the object’s properties and dimensions as needed.

Performing Basic Modeling Tasks

FreeCAD offers a range of basic modeling tools, including:

• Extrusion: creates a solid object from a 2D shape.
• Boolean Operations: combines or subtracts objects using set operations.
• Fillets: adds rounded edges to a solid object.
• Chamfers: adds angled edges to a solid object.
