How Many Linetypes Are in AutoCAD?

In AutoCAD, there are several linetypes available that can be used to represent different objects and elements in a drawing. Linetypes are essential for enhancing the visual clarity of drawings and conveying important information. Let’s explore the various linetypes in AutoCAD and how they can be utilized effectively in your designs.

Continuous Linetype

The Continuous linetype is the default linetype in AutoCAD. It represents continuous lines without any breaks or gaps. It is commonly used to depict visible objects such as walls, boundaries, and edges.

Centerline Linetype

The Centerline linetype is used to represent centerlines of circles, arcs, or other symmetrical objects. It consists of long and short dash segments with a small gap between them. This linetype helps to indicate the central axis of an object.

Dashed Linetype

The Dashed linetype is widely used to display hidden or non-visible edges of an object. It consists of evenly spaced dash segments separated by small gaps. This linetype creates a dotted appearance, making it easy to distinguish hidden features.

Phantom Linetype

The Phantom linetype is often used to indicate alternate positions or temporary objects in a drawing. It consists of long dashes followed by short gaps, creating a distinctive pattern. This linetype helps differentiate temporary or optional elements from permanent ones.

Center Mark Linetype

The Center Mark linetype is specifically designed for representing center marks on circles and arcs. It consists of alternating long and short dash segments with small gaps between them. This type of line makes it convenient to identify the center points accurately.

List of Additional Linetypes:

  • Dashed Hidden: Similar to the Dashed linetype, but with shorter dashes and longer gaps. It is commonly used for hidden features that are less significant.
  • Phantom2: A variation of the Phantom linetype, with a different pattern of dash segments and gaps.

    It offers flexibility in representing temporary or alternate positions.

  • Dot: Consists of evenly spaced dots, ideal for indicating points or small objects in a drawing.
  • Divide: Comprises short dash segments separated by small gaps. It is useful for dividing or separating objects into equal parts.

In AutoCAD, you can also create custom linetypes to suit your specific requirements by using the LINETYPE command. This allows you to define unique patterns using different combinations of dashes, dots, and spaces.

Remember that proper utilization of linetypes can significantly improve the readability and understanding of your drawings. By employing appropriate linetypes for different elements, you can effectively communicate the intended information and enhance the overall visual appeal of your designs in AutoCAD.
