ENGINEERING DATA EXCHANGE

Accepted File Formats

Complete, consistent design files help engineering and production teams quote the same geometry and revision.

2D and 3D Files for Manufacturing Review

We accept common drawing and model formats used for custom metal parts. A controlled PDF drawing should define dimensions, tolerances, materials and finishes even when a 3D model is supplied.

Commonly Accepted Formats

  • PDF for controlled drawings and specifications
  • DXF and DWG for 2D profiles and fabrication details
  • STEP and STP for neutral 3D model exchange
  • JPG and PNG for marked-up references
  • BOM and supporting documents in common office formats
CNC control system used for custom metal manufacturing

Recommended File Package

  1. Include a revision-controlled PDF drawing.
  2. Provide STEP/STP for complex formed or machined geometry.
  3. Identify units, material grade and surface treatment.
  4. Mark critical dimensions and inspection requirements.
  5. Include quantity, application and assembly context.

File Consistency Check

If the 2D drawing and 3D model differ, production does not proceed on assumption. The discrepancy is raised for confirmation and the approved source of truth is recorded.
