Data preparation checklist

• Establish and enforce 3D CAD design standards.
• Change systems to reward design quality, not quantity.
• The organization creating 3D CAD data is responsible for its accuracy.
• Obtain and use tools that improve data translations and data integrity.
• Drafting checkers should implement data integrity checking criteria.
• Revise CAD-generated documents using your CAD system.
  DO NOT REVISE MANUALLY!
  
• Don't mark revisions manually on paper.
