🧭 Lesson Content

🔹 1. Introduction to Attributes

  • Attributes are text-based fields embedded in blocks.
  • Used to track part numbers, dates, vendor names, etc.
  • Unlike regular text, they store data and can be extracted.

🔹 2. Defining Attribute Fields

  • Command: ATTDEF
  • Key fields:
    • Tag (name of the attribute)
    • Prompt (what the user sees during insert)
    • Default (default entry if user skips it)
  • Options: Invisible, Constant, Verify, Preset, Lock Position

Example:

Tag: PART_NO
Prompt: Enter Part Number:
Default: 0001

🔹 3. Creating Blocks with Attributes

  • Create geometry (e.g., rectangle)
  • Use ATTDEF to create 2–3 fields
  • Combine geometry and attributes using BLOCK command

🔹 4. Inserting and Editing Attributes

  • Use INSERT to place the attributed block
  • AutoCAD will prompt user for data
  • Use ATTEDIT or EATTEDIT to update fields later

🔹 5. Managing Attributes with BATTMAN

  • Command: BATTMAN
  • Attribute Block Manager allows:
    • Reordering attribute prompts
    • Updating block definitions
    • Synchronizing block references

🔹 6. Attribute Visibility and Prompt Order

  • Some attributes can be hidden (e.g., date codes)
  • Change prompt order in block definition or BATTMAN
  • Use the REGEN command to update the drawing view

🔹 7. Extracting Attribute Data

  • Use DATAEXTRACTION wizard:
    1. Select blocks to extract from
    2. Choose which attributes to export
    3. Output as .xls, .csv, or AutoCAD table

🛠️ Hands-On Exercise

Task: Create a title block with 3 attributes:

  • DRAWING_NAME
  • DATE
  • DRAWN_BY
  1. Create the title block geometry
  2. Define attributes using ATTDEF
  3. Insert the block and enter sample data
  4. Export the data using DATAEXTRACTION

Save as: titleblock_attributes.dwg

🧠 Knowledge Check

  1. What is the difference between ATTEDIT and EATTEDIT?
  2. What command is used to define an attribute?
  3. How do you export all part numbers from a drawing?
  4. What does BATTMAN allow you to do?

✅ Completion Checklist

✔ Created attributes with ATTDEF
✔ Built and inserted an attributed block
✔ Edited attributes with multiple tools
✔ Extracted block data for external use
✔ Passed the knowledge quiz
