Understanding Clipping References in AutoCAD
Clipping references in AutoCAD is a crucial process for managing the visibility of external references (Xrefs), images, or underlays within your design. This article provides a detailed guide on how to clip a reference and manage clipping boundaries effectively.
What is Clipping in AutoCAD?
Clipping allows users to define a specific area of an external reference or image to be visible while hiding the rest. This feature is particularly useful in complex drawings where clarity and focus on a particular section are necessary.
Steps to Clip an Xref in AutoCAD
-
Select the External Reference:
- Open your AutoCAD project and navigate to the drawing area.
- Click on the Xref you wish to clip to select it.
-
Access the Clipping Tool:
- Go to the External Reference tab located in the top ribbon.
- Click on the Clipping Panel to expand your options.
-
Create Clipping Boundary:
- Select Create Clipping Boundary from the available options.
- If prompted about deleting an existing boundary, consult with your drawing needs and respond accordingly.
-
Define the Clipping Area:
- You will be prompted to select the boundary type. Here, you can either select a predefined polyline or use a shape by specifying rectangular or polygonal vertices.
- Click to set the corners or vertices of your chosen boundary.
-
Finalizing Clipping:
- Once you have specified the area, press Enter. The Xref will now appear clipped, showing only the section you defined.
What is a Clipping Boundary?
A clipping boundary is essentially a defined area within an object that determines which portion will be visible and which will be hidden. This boundary can be applied to various elements like images, underlays, and Xrefs. The visibility of clipping boundaries is controlled by the FRAME system variable, allowing you to toggle between visible and hidden states.
How to Bind Xrefs in AutoCAD
Binding Xrefs is an essential step when integrating external references into your working drawing.
-
Open the External References Palette:
- Navigate to the Insert tab and locate the Reference Panel. Click on the dialog box launcher.
-
Select the Reference:
- From the External References palette, find and select the name of the reference you wish to bind.
-
Binding Process:
- Right-click on the selected reference and choose Bind.
- In the Bind Xrefs dialog, you will have options for how to bind the reference (Bind or Bind as Attachment). Choose the suitable option.
-
Complete Binding:
- Press OK to finalize your choices and close the dialogs.
How to Remove Clipping Boundaries
If a clipping boundary is no longer needed, it can be removed easily following these steps:
-
Access the Modify Menu:
- Click on the Modify menu and then select Clip Image.
-
Select the Clipped Image:
- Click on the image or Xref that has the clipping boundary you wish to delete.
-
Delete the Boundary:
- Enter “d” for Delete. This action will remove the clipping boundary and restore the original view of the image or Xref.
Hiding Clipping Boundaries
To control the visibility of clipping boundaries:
-
Modify Image Frame Settings:
- Go to the Modify Menu and select Object, then Image Frame.
-
Choose Visibility Options:
- To hide image boundaries, enter 0. To show and plot the boundaries, enter 1; to show them without plotting, enter 2.
FAQ
1. Can I bind a PDF in AutoCAD?
Currently, binding an attached PDF directly is not supported in AutoCAD. Instead, you can convert the PDF into a raster image or use a screenshot, which can then be inserted into your project.
2. How do I edit Xclip boundaries after creating them?
To edit existing Xclip boundaries, navigate to the Modify menu, select Clip, and then choose Xref. Select the Xref and press Enter to specify a new boundary.
3. What is the difference between ‘Bind’ and ‘Insert’ for Xrefs in AutoCAD?
The ‘Bind’ method converts Xref objects into a block reference while merging named object definitions into the current drawing. The ‘Insert’ method also converts references but does so without adding prefixes to the names in the current drawing.
