Dictionary<string, ObjectId> blockCache = new Dictionary<string, ObjectId>();

"AutoCAD Block Net" represents two pathways to dramatically improved productivity. For programmers and power users, the offers unparalleled control over block creation, insertion, and management — enabling automation that would be impossible through manual commands alone. From simple block insertion routines to complex dynamic block manipulation and library management systems, the API puts the full power of AutoCAD's database at your fingertips.

The process, as documented by Autodesk support, involves creating AttributeDefinition objects within your BlockTableRecord. You specify each attribute's position, default text, tag name, and prompt string. Then, when inserting the block reference, you iterate through the block definition to find its attribute definitions and create corresponding AttributeReference objects populated with values.
