   • Ask questions, share your projects, and learn from others.
6. Experiment and Practice:
   • Start with simple projects, such as designing a basic mechanical part or a small household item.
   • Gradually move on to more complex designs as you gain confidence.

FreeCAD Use Cases

• Hobbyists: Create 3D models for 3D printing, robotics, or DIY projects.
• Students: Learn 3D design and engineering concepts without spending money on software.
• Educators: Teach CAD, architecture, or engineering using a free and accessible tool.
• Professionals: Use FreeCAD for prototyping, product design, or small-scale manufacturing.

Tips for Success

• Be Patient: FreeCAD has a learning curve, especially if you’re new to CAD. Take your time to understand the tools and workflows.
