How To Create Defpoint Layer In AutoCAD?

Understanding the Defpoint Layer in AutoCAD

The Defpoint Layer is a unique layer in AutoCAD that serves a specific purpose. It is primarily used for placing definition points related to dimensions, such as extension lines and dimension text. Unlike other layers, the Defpoint layer does not plot, which means any objects placed on it will not appear when a drawing is printed. This layer is essential for organizing and managing dimensioning elements effectively.

Steps to Create a Defpoint Layer

1. Open the Layer Properties Manager:

   • Type LA in the command line. This command opens the Layer Properties Manager, where you can manage various layers in your drawing.

2. Create a New Layer (Optional):

   • Click on the "New Layer" icon or use the shortcut provided.
   • Type a name for the layer (typically "Defpoints" is used). You can add descriptive notes for better organization.

3. Set the Layer Properties:

   • Ensure that the new layer is well-defined with properties such as color, linetype, and line weight. Setting these properties helps in distinguishing the layer visually.
4. Adjust the Plot Option:
   • Locate the Plot column in the Layer Properties Manager. If it isn’t displayed, right-click on a column header and select the “Plot” option to make it visible.
   • Make sure to leave the Plot option unchecked to ensure that objects on this layer do not print.

Utilizing the Defpoint Layer

1. Creating Dimensioning Points:

   • When dimensions are created using AutoCAD, they automatically use the Defpoints layer for their reference points. This can save time and keeps dimensioning organized.
   • Use the dimensioning tools (such as linear or angular dimensions) and note that the points will fall onto the Defpoints layer by default.
2. Moving Objects to the Defpoint Layer:
   • If you have any existing points or elements that need to be moved to the Defpoints layer, select them, right-click, and choose ‘Properties.’
   • Change the layer to Defpoints from the drop-down menu under the Layer section.

Viewing and Managing Defpoints

1. Switching to Model Space:

   • To effectively manage your layers, navigate to Model Space where the main drawing occurs. Make sure you can see your Defpoints layer in action.
2. Setting Layers for Viewports:
   • If you have multiple viewports, you may want the Defpoints layer visible across all of them. From the Layer Properties Manager, select the Defpoints layer and ensure it is set for all viewports.

FAQ

1. Why can’t I see my Defpoint layer in the drawing?

• If a layer is not showing, ensure that it is not frozen or turned off in the Layer Properties Manager. Also, check the visibility settings for the current viewport.

2. Can I modify the properties of the Defpoint layer?

• Yes, while the Defpoints layer is meant for specific uses, you can modify its color and linetype as long as it’s in accordance with your project standards.

3. What happens if I switch the Plot option on for the Defpoints layer?

• If you enable the Plot option for the Defpoints layer, the elements placed on this layer will print normally. However, it can clutter your drawing deliverables, as these points are usually meant to be non-printed reference marks.
