Module 10: Blocks and annotation

Notes for offline study · 3 November 2026

Dynamic blocks

Key points

  • Dynamic blocks change size, shape or visibility without making new blocks.
  • Parameters and actions are added in the Block Editor to define the changes.
  • One dynamic block can replace many nearly identical static blocks.

Block attributes and data extraction

Key points

  • Attributes store text data such as part numbers inside a block.
  • ATTDEF defines an attribute; values are filled in when the block is inserted.
  • Data Extraction collects attribute values into a table or an Excel file.
