What Does Defpoints Mean in AutoCAD?

AutoCAD is a powerful software that is widely used in the field of computer-aided design (CAD). It provides various tools and features to create precise and detailed drawings.

One of the terms that you may come across while working with AutoCAD is “Defpoints”. In this article, we will explore what Defpoints means in AutoCAD and how it can be used.

What is Defpoints?

Defpoints is a special layer in AutoCAD that is automatically created when you start a new drawing. The name “Defpoints” stands for “Default Points”. This layer is unique because it has some distinct properties that set it apart from other layers.

The Properties of Defpoints Layer

The Defpoints layer has two main properties:

  • Visibility: By default, the objects on the Defpoints layer are invisible. This means that they will not be plotted or printed when you generate a final output such as a physical drawing or a PDF file.

    However, they can still be visible on the screen while you are working on your drawing.

  • Persistent: The objects on the Defpoints layer are persistent, which means that they cannot be erased or deleted. This ensures that any objects placed on this layer will always remain in your drawing, even if you accidentally delete other layers or turn them off.

The combination of these properties makes the Defpoints layer useful for certain purposes in AutoCAD.

Common Uses of Defpoints Layer

The Defpoints layer can be utilized for various purposes, including:

  • Construction Lines: You can use the Defpoints layer to create construction lines or reference lines that help you align and measure other objects in your drawing. Since these lines are not meant to be part of the final output, they can be placed on the Defpoints layer.
  • Annotation Guidelines: When adding text or dimensions to your drawing, you may want to ensure that they are aligned or spaced correctly.

    You can create guidelines on the Defpoints layer to assist you in positioning your annotations accurately.

  • Temporary Objects: If you need to create temporary objects for testing or experimentation purposes, you can place them on the Defpoints layer. These objects won’t clutter your main drawing layers and can be easily hidden or shown as needed.

Working with Defpoints Layer

To work with the Defpoints layer in AutoCAD, follow these steps:

  1. Create a new drawing or open an existing one.
  2. Select the “Layers” panel from the “Home” tab in the ribbon.
  3. In the “Layers” panel, click on the “Layer Properties” button to open the Layer Properties Manager.
  4. In the Layer Properties Manager, locate and select the “Defpoints” layer.
  5. You can now start adding objects to the Defpoints layer by selecting it from the layer dropdown menu when creating new geometry or modifying existing ones.

Note that while working with the Defpoints layer, it’s essential to remember its properties of being invisible and persistent. Take care not to accidentally plot or print any objects on this layer if they are not intended for final output.


In conclusion, Defpoints is a unique layer in AutoCAD that has special properties of invisibility and persistence. It is primarily used for construction lines, annotation guidelines, and temporary objects. By understanding and utilizing the Defpoints layer effectively, you can enhance your productivity and organization in AutoCAD.
