QUESTION
I'm not able to explode a CAD block. When I click the Explode CAD Block edit button, I receive the following message:
- "#272011622 - Cannot explode block when x and y scaling are different."
What does this mean?
ANSWER
CAD blocks are a collection of lines, polylines, and other CAD objects that have been grouped together to form a single object that can be easily placed, selected, and moved without affecting the appearance of the drawing. To edit the objects that make up a CAD block, it must first be unblocked; however, if the CAD block has been stretched and adjusted so that the Height and Width Factors are no longer the same, it cannot be unblocked.
To explode a resized CAD block
- Using the Select Objects
tool, click on the CAD block to select it, then click the Open Object
edit button.
- On the General panel of the CAD Block Specification dialog, specify a value of 1.0 for both the Height Factor and Width Factor, then click OK.

-
With the CAD block still selected, click the
Explode CAD Block 
edit button to break the CAD block into its individual components for editing, or click on the
Edit CAD Block 
edit button instead to open a separate window where you can edit the individual components.
