How to Convert Arc to Polyline in AutoCAD?

Step-by-Step Guide to Convert Arc to Polyline in AutoCAD

Understanding the Basics of AutoCAD Polylines

Polylines in AutoCAD are essential for creating complex shapes and designs. An arc is a curved line defined by a center point, radius, and angle, while a polyline is a connected sequence of line segments. Converting arcs to polylines can enhance editing capabilities, as polylines allow for more extensive modifications.

Steps to Convert an Arc to a Polyline in AutoCAD

1. Initiate the Polyline Edit Command

   • Begin by typing PEDIT in the command line. This command is designed for editing polylines.

2. Select Multiple Objects

   • After entering the command, type M for multiple selections. This allows you to choose more than one arc or spline to convert simultaneously.

3. Select Your Arcs

   • Click on the arc(s) you wish to convert. If your selection is correct, you will see them highlighted on your workspace.

4. Convert to Polyline

   • When prompted, type Y (for "Yes") to confirm that you want to convert those lines, arcs, and splines into polylines. This step is crucial for the conversion process.

5. Determine Precision

   • Specify your desired precision level when prompted. This step will affect how closely the resultant polyline adheres to the original arc.
6. Finish the Command
   • To exit the command, simply press the Esc key. Your arcs should now be transformed into polylines ready for further modification.

Checking Converted Polylines

After conversion, it is essential to verify the integrity of your new polylines. Use the LIST command to check properties like length and angles, ensuring that the conversion process worked correctly.

Frequently Asked Questions (FAQs)

1. Can I convert multiple arcs in one go?
Yes, using the M option in the PEDIT command allows you to select multiple arcs and convert them simultaneously.

2. Will the conversion affect the original curves?
No, the original arcs will be replaced by polylines that are approximations of their shapes based on the specified precision.

3. What if my arcs are part of a complex shape?
If the arcs are part of a larger object, consider exploding the object first using the EXPLODE command. This way, each arc can be separately converted into polylines.
