PolyLine Command in AutoCAD

The PolyLine command in AutoCAD is a versatile tool used to create a single object made up of connected lines or arcs. Unlike the Line command, which creates separate line segments, PolyLine creates a continuous object, making it easier to manipulate as a whole. This guide explains how to use the PolyLine command step by step.

How to Use the PolyLine Command

Follow these steps to create and work with PolyLines:

Step 1: Activate the PolyLine Command

To start the PolyLine command, you can:

  • Type PLINE in the command line and press Enter.
  • Click the PolyLine icon in the Draw toolbar or ribbon (if available).

Step 2: Specify the Start Point

After activating the PolyLine command, AutoCAD will prompt you to specify the starting point. You can:

  • Click anywhere in the drawing area to set the starting point.
  • Enter the coordinates of the starting point in the command line (e.g., 10,10).

Step 3: Define the Next Segment

AutoCAD will then prompt you to specify the next point or segment. You can choose from the following options:

  • Click a point or enter coordinates to create a straight line segment.
  • Type A (Arc) and press Enter to draw a curved segment.
  • Type L (Line) to return to drawing straight segments.

Step 4: Continue Adding Segments

You can continue adding line or arc segments to your PolyLine by specifying points or switching between arc and line modes. The segments will remain connected, forming a single object.

Step 5: Close or End the PolyLine

When you are finished, you can:

  • Type C (Close) and press Enter to connect the last point to the first, creating a closed shape.
  • Press Enter or Esc to end the command without closing the shape.

Step 6: Edit the PolyLine (Optional)

PolyLines can be edited using the PEdit command. To do this:

  • Type PEdit in the command line and press Enter.
  • Select the PolyLine you want to edit.
  • Choose options like joining, splitting, or converting segments to arcs.

Advantages of Using PolyLine

The PolyLine command offers several benefits:

  • Creates a single object, simplifying manipulation and editing.
  • Supports both straight and curved segments in the same object.
  • Works well with commands like Offset, Fillet, and Join.

Conclusion

The PolyLine command is a powerful tool in AutoCAD for creating complex shapes and designs. By following the steps outlined above, you can effectively use this command to create and manage continuous objects. Practice combining straight and curved segments to fully utilize its capabilities.
