Organic Shape DXF Conversion

I need a simple DXF file created from an organic shape in a PDF. The DXF doesn't need to be exact, but the height and width must be accurate.

Requirements:
- Convert organic shape from PDF to DXF
- Similarity to original shape is acceptable
- Dimensions must be accurate (height and width)
- No additional details or annotations needed

Ideal Skills & Experience:
- Proficiency in CAD software
- Experience with DXF file creation
- Familiarity with organic shapes and CNC machining requirements
