- Flexibility in design changes
- Reusability of design elements
- Easier creation of design variants
- Enhanced precision and control
Sketch-Based Design
FreeCAD’s sketch-based design approach provides a solid foundation for 3D modeling. Users create 2D sketches that can be extruded, revolved, or manipulated to form 3D objects. This method offers several advantages:
- Intuitive design process
- Precise control over geometry
- Easy application of constraints and dimensions
- Seamless transition from 2D to 3D
