There can be a variety of reasons why an object cannot be decomposed in AutoCAD, which needs to be analyzed and addressed on a case-by-case basis. There are several solutions: Fall/Winter Check-in Challenge
Check if the object is locked or frozen, and if so, unlock or unfreeze it before attempting to disassemble;
Check if the object is a block or xref, and if so, you can make a block or reference edit before attempting to explode;
Check if the object is a compound object, such as a polyline, region, fill, etc., and if so, you can use the explode command to convert it to a simple object before attempting to explode;
Check if the object is a custom object, such as a dynamic block, a parameterized block, etc., if so, you can use the burst command to convert it to a standard object first, and then try to decompose;
If none of the above methods work, it may be that the object itself does not support decomposition, or it may be due to a program error. At this point, you can try to use other tools or methods to achieve the purpose of decomposition, such as using the copy command to copy the object and then delete the original objectAlternatively, use the wblock command to write the object to a new drawing file and then import it back into the original drawing file.
Let's take a chestnut: sometimes we need to break down some graphics with text in order to modify or adjust. But if these graphics are multiline text objects created by the mtext command, then we can't break them up directly. At this point, we can use the txtexp command to convert a multi-line text object to a single-line text object with the original formatting and attributes. Then we can break down and edit the single-line text object.
