🔧 Lesson Content

🔹 1. What is WBLOCK?

  • Stands for Write Block
  • Exports a selection of drawing objects as a separate DWG file
  • Useful for creating reusable content or sharing components with others

🔹 2. When to Use WBLOCK

  • You need to share a single block from a larger file
  • You want to create a centralized library of dynamic or static blocks
  • You need to insert common elements (e.g., furniture, logos, details)

📐 Creating a WBLOCK

🔸 Command: WBLOCK

  1. Type WBLOCK or use the ribbon: Insert → Block Definition → Write Block
  2. Choose:
    • Entire drawing or Selected objects
    • Base point: Choose carefully for alignment during reinsertion
    • Destination file: Choose folder and file name
  3. Set file format (e.g., AutoCAD 2018 DWG for compatibility)

Tip: Save to a known directory (like “Block Library”) to reuse later

📁 File Management and Export Tips

  • Use clear, consistent naming conventions:
    chair-round.dwg, outlet-120v.dwg
  • Organize in folders by discipline or category
  • Avoid naming blocks “Block1”, “Test”, etc.
  • Exported WBLOCKs are standalone DWG files and open like normal drawings

🔁 Using Exported Blocks

  • Use INSERT, DESIGN CENTER, or TOOL PALETTES to bring in blocks
  • Check layer assignment and base point upon insertion
  • Optionally use Tool Palettes for drag-and-drop simplicity

🛠️ Hands-On Exercise

Task:
Select an object or group (e.g., a custom table or fixture) from your drawing.

  1. Use WBLOCK to export it to a new DWG file
  2. Close the current drawing
  3. Open a new drawing and INSERT your WBLOCK file
  4. Align and verify correct base point, layer, and scale

Save as: exported_block_test.dwg

🧠 Knowledge Check

  1. What is the key difference between BLOCK and WBLOCK?
  2. Why is selecting the base point carefully so important?
  3. What are two ways to reuse a saved WBLOCK in other drawings?
  4. What’s the risk of using vague block names like “temp1”?

✅ Completion Checklist
