How Many Types of Lines Are There in AutoCAD?

AutoCAD is a powerful software that is widely used for designing and drafting in various industries. When working with AutoCAD, it is important to have a good understanding of the different types of lines that can be used. In this article, we will explore the various types of lines available in AutoCAD and their uses.

The Basics

Lines are one of the fundamental elements in AutoCAD. They are used to represent objects and define their shape and size. In AutoCAD, there are several types of lines that can be used:

  • Continuous Line: This is the default line type in AutoCAD. It consists of a series of connected line segments.
  • Dashed Line: Dashed lines are made up of a series of dashes separated by spaces.

    They are often used to represent hidden or non-visible edges.

  • Dotted Line: Dotted lines consist of a series of dots evenly spaced along the line. They are commonly used to indicate construction or temporary lines.
  • Centerline: Centerlines are composed of alternating long and short dashes with a dash-dot at each end. They are typically used to represent symmetry or axes.

The Importance of Line Types

The choice of line type in AutoCAD depends on the purpose and context of the drawing. Different line types can convey different meanings and help improve the clarity and readability of the design.

Bold lines can be used to emphasize important features or boundaries within a drawing. For example, you might use bold lines for outlining walls or major structural elements.

Underlined lines, on the other hand, can be used to indicate dimensions or measurements. This can help viewers understand the size and scale of objects in the drawing.

Creating Different Line Types in AutoCAD

AutoCAD provides several options for creating and customizing line types. You can access these options through the “Line Type” dialog box.

  1. To create a dashed line, select the desired line segment and set its “Line Type” property to “Dashed”.
  2. To create a dotted line, set the “Line Type” property to “Dotted”.
  3. To create a centerline, set the “Line Type” property to “Center”.

In addition to these built-in line types, AutoCAD also allows you to create custom line types using the “Linetype Manager”. This feature enables you to define your own patterns or import existing ones.


In conclusion, AutoCAD offers a range of line types that can be used to enhance your drawings. Understanding the different types of lines available and their uses is essential for creating clear and professional designs. By utilizing bold text, underlined text, lists, and subheaders effectively within your article, you can ensure that your readers grasp this important information while also engaging them visually.
