To separate the lines of a rectangle in AutoCAD, you typically use the EXPLODE command. This command converts a compound object, such as a polyline (which a rectangle created with the RECTANG command usually is), into its individual component objects.
Using the EXPLODE Command to Separate Rectangle Lines
When you draw a rectangle in AutoCAD using the RECTANG command, it is created as a single, closed polyline object. This means all four sides are treated as one entity. To work with each side independently—for example, to move, trim, or extend just one side—you need to break it down into separate line segments. The EXPLODE command is designed precisely for this purpose.
Step-by-Step Guide to Exploding a Rectangle
Follow these simple steps to separate the lines of your rectangle:
- Select the Object: In your AutoCAD drawing, click on the rectangle you wish to separate. The entire rectangle will highlight, indicating it's a single object.
- Initiate the EXPLODE Command:
- Type
EXPLODE(or its aliasX) in the command line and press Enter. - Alternatively, you can find the Explode icon on the Home tab in the Modify panel of the ribbon interface.
- (See image below for typical Explode icon location)

- Type
- Confirm Selection (if not already selected): If you typed the command first, AutoCAD will prompt you to "Select objects to explode." Click on the rectangle and then press Enter to confirm. If you selected the rectangle first, the command will execute immediately.
- Observe the Result: After executing the command, the rectangle will no longer be a single object. When you hover over or select any side, only that individual line segment will highlight. You can now manipulate each of the four lines independently.
Why Explode a Rectangle?
Exploding a rectangle offers several practical advantages for editing and drafting:
- Individual Editing: Allows you to modify specific sides without affecting the others. For example, you can extend one side, trim another, or change the properties (like layer or linetype) of a single line.
- Command Compatibility: Some AutoCAD commands, like
OFFSETorFILLET, behave differently or only work on individual line segments rather than entire polylines. - Simplification: Breaks down complex objects into simpler, fundamental entities, which can sometimes be easier to manage, especially in intricate drawings.
- Data Extraction: If you need to extract data about individual line lengths or properties, exploding ensures you're working with the basic geometric components.
AutoCAD Command Summary: EXPLODE
Here’s a quick reference for the EXPLODE command:
| Command Name | Alias | Location (Ribbon) | Function | Result |
|---|---|---|---|---|
EXPLODE |
X |
Home tab > Modify panel | Breaks a compound object into its components | Converts a rectangle (polyline) into four individual line objects |
For more detailed information on the EXPLODE command, you can refer to the Autodesk Knowledge Network.
Considerations
- Reversibility: The
EXPLODEcommand is irreversible with a single command once you perform other actions. However, you can always use theUNDOcommand immediately after exploding if you make a mistake. - Block References: The
EXPLODEcommand can also be used on block references to break them down into their constituent objects, but be aware that it removes the block definition from that instance.
By using the EXPLODE command, you gain precise control over the individual elements of your AutoCAD drawings, making your editing process more flexible and efficient.
