1、Overview of 3D Modeling Methods
1.1 Parametric Modeling
Key Features: Parameterdriven, generates/modifies models using geometric parameters and constraints
Advantages: High precision, structured geometric shapes
Best for: Engineering design, product development, architecture
Paid Alternatives: SolidWorks, UG, Creo
1.2 Freeform Modeling
Key Features: Manual sculpting for complex organic shapes
Advantages: High artistic flexibility, strong visual appeal
Best for: Art, animation, game design
Paid Alternatives: ZBrush, Maya

- Important Notes
- Some software requires higher hardware specs (e.g., Blender)
- Prioritize tools with Chinese UI support if needed
- Always check model integrity before export (wall thickness, normals, etc.)
- For complex projects, combine multiple tools (e.g., Blender + Meshmixer)
