Have you ever sent a DXF file to your machining supplier, only to receive confusing feedback about layer settings? Or worse, gotten parts back that don’t match your design intent? These layer-related miscommunications can lead to costly delays and frustrating revisions.

A machining-ready DXF file requires specific layer settings for different design elements. Critical layers include cutting paths, dimensions, text annotations, and internal features. Proper organization of these layers ensures accurate interpretation and machining of your design.

Understanding Layer Hierarchy in DXF Files

Layer management in DXF files follows a hierarchical structure that helps organize design elements. When preparing files for CNC machining, proper layer organization is crucial for successful manufacturing outcomes. The most important layers typically include:

Primary Cutting Path Layer

The outer profile layer defines the main cutting path for your part. This layer should:

• Be clearly named (e.g., "CUT_PROFILE" or "OUTER_CONTOUR")
• Contain only closed polylines
• Use consistent line types
• Be placed on a separate layer from internal features

Internal Feature Layers

Internal features require careful organization to prevent machining errors. At PTSMAKE, we recommend separating different types of internal features into distinct layers:
