Learn how to combine machine learning, rules engines, and domain expertise to map resources from different source systems. Understand how machine learning and rules detect potential matches between entities from different data sources. ## Match and connect entities Match CDF resources to assets using pipelines, quick match, or 3D model matching. Extract information from static engineering diagrams to create interactive diagrams you can explore on any device. ## Parse diagrams and documents Extract information from engineering diagrams by detecting and mapping assets and files in CDF. Detect, extract, and map asset tags, file references, symbols, and connections to create a structured knowledge graph. Extract data from documents with key-value data representation into data model views. Create and modify symbol libraries to add new symbols or geometries for diagram parsing. ## Reference Resolve issues and errors related to interactive diagram parsing in CDF.
