Autodesk Certified Professional in AutoCAD for Design and Drafting Practice Exam

When using the WBLOCK command, if Block is selected as the source, what does not need to be specified?

1. The block's base point.

2. The block's name.

3. The block's dimensions.

4. The block's layer.

The correct answer is: The block's base point.

When utilizing the WBLOCK command in AutoCAD to create a new block from an existing one, specifying the block's base point is not required because the block inherently has a defined base point associated with it. When you select an existing block as the source, AutoCAD automatically uses the base point that was set when the block was originally created. This is contrary to defining a new block where the base point must be manually specified to establish where the block will insert within the drawing. In contrast, the block's name must be provided to identify the new block being created. The block's dimensions are intrinsic to how the block is defined and do not need separate input during the WBLOCK process. Similarly, the block's layer is maintained, but a new layer can also be specified during the WBLOCK creation if necessary. Therefore, knowing that the base point is already set in the existing block clarifies why it does not need to be duplicated in the WBLOCK command process.
