What is the key difference between BLOCK and WBLOCK commands in AutoCAD?
What is the key difference between BLOCK and WBLOCK commands in AutoCAD?
- BLOCK commands are used to create blocks only in the current drawing, while WBLOCK commands store blocks as new drawing files for later use. (correct)
- BLOCK commands are used to insert blocks into other drawings, while WBLOCK commands are used to create blocks within the same drawing.
- BLOCK commands are used to edit existing blocks, while WBLOCK commands are used to reference external blocks.
- BLOCK commands are used to change block properties, while WBLOCK commands are used to rotate blocks.
When should objects defining blocks be drawn on layer 0?
When should objects defining blocks be drawn on layer 0?
- To edit the properties of the block.
- To retain properties such as linetype and color of the layer where the objects were drawn. (correct)
- To inherit properties such as linetype and color of the layer where the block is inserted.
- To make the block invisible.

Study Notes
Editing Blocks
- Double-click on a block to edit it, which opens the "Edit Block Definition" dialog box.
- Alternatively, use the command line: BEdit or BE to access the "Edit Block Definition" dialog box.
- Make changes to the block and save them before closing the window.
Reference Edit
- Use the Refedit command to edit blocks in place.
- Command line: Refedit => "Reference Edit" Dialog Box will appear.
- The objects of a block will be isolated on the drawing for editing in place.
- Save (or discard) changes and exit by making a selection from the Refedit bar.
Renaming Blocks
- Use the Rename command to rename a block.
- Command line: Rename => "Rename" Dialog Box will appear.
Deleting Unused Blocks
- Note: You CANNOT delete blocks that are currently in use!
- Use the Purge command to delete unused blocks.
- Command line: Purge => Type information in the command line.
- Command line: Purge => "Purge" Dialog Box will appear.
Blocks vs. WBlocks
- The BLOCK command creates blocks that can only be used in the dwg in which they were created.
- The WBLOCK command stores blocks as new drawing files that can later be inserted into any dwg.
Using WBLOCK Command
- Use the WBlock command to create blocks that can be used in any dwg.
- Command line: Type WBlock or WB in the command line => "Write Block" Dialog Box will appear.
Checking Layers
- Objects must be drawn on layer 0 for blocks to inherit layer properties.
- Draw objects on a specific layer to retain properties such as linetype and color.
Inserting Blocks
- Use the INSERT command to insert a block.
- Command line: Type CLASSICINSERT (Insert, I) in the command line => "Insert" Dialog Box will appear.
