Can You Convert Lines to Polylines in AutoCAD?

AutoCAD is a powerful software tool used by architects, engineers, and designers for creating precise 2D and 3D drawings. One common task that frequently arises when working with AutoCAD is the need to convert lines to polylines. In this tutorial, we will explore how to perform this conversion easily using AutoCAD’s built-in tools.

What are Lines and Polylines in AutoCAD?

Before diving into the conversion process, it’s essential to understand the basic concepts of lines and polylines in AutoCAD.

Lines:

A line is a simple geometric element in AutoCAD that consists of two distinct points connected by a straight path. It represents a single entity with properties such as color, linetype, and layer.

Polylines:

A polyline, on the other hand, is a more complex object made up of one or more line or arc segments that are joined together. It can be thought of as a series of connected lines or arcs forming a continuous shape. Polylines have additional properties compared to lines, such as width, vertex coordinates, and closed or open status.

Converting Lines to Polylines

Now let’s explore the step-by-step process of converting lines to polylines in AutoCAD:

Method 1: Using the PEDIT Command

  1. Type “PEDIT” in the command line and press Enter.
  2. Select the line(s) you want to convert by clicking on them individually or using a window selection.
  3. Press Enter again when you have finished selecting the lines.
  4. In the prompt that appears, type “Y” and press Enter to convert the selected lines into a polyline.
  5. AutoCAD may ask you to specify the width of the polyline. You can either choose a specific value or press Enter to keep it as zero.
  6. The lines are now converted into a polyline. You can verify this by hovering over the object and observing its properties in the Properties palette.

Method 2: Using the Join Command

  1. Type “JOIN” in the command line and press Enter.
  2. Select one line as the “source” by clicking on it.
  3. Select additional lines that you want to join to the source line. You can continue selecting multiple lines until you have included all desired lines.
  4. Press Enter when you have finished selecting lines.
  5. The selected lines will be joined together into a single polyline. Again, you can verify this by checking its properties in the Properties palette.

Tips for Working with Polylines

Now that you know how to convert lines to polylines, here are some useful tips for working with polylines in AutoCAD:

  • Closing Polylines: To close an open polyline, use the PEDIT command and select “Closed” from the prompt options. Alternatively, you can use the JOIN command and select both endpoints of an open polyline to close it automatically.
  • Edit Vertexes: To modify a polyline’s shape, use tools like PEDIT or grips.

    You can add or remove vertexes, move vertexes, or adjust curve segments as needed.

  • Polyline Width: Polylines can have width properties, which control their visual appearance when plotted or displayed. You can adjust the width of a polyline using the PEDIT command or by modifying its properties in the Properties palette.

By mastering these techniques, you’ll be able to efficiently work with both lines and polylines in AutoCAD, saving time and enhancing your productivity.

Remember to practice regularly to become familiar with these features and explore other advanced functionalities offered by AutoCAD. Happy designing!
