A proxy object in AutoCAD is a special type of object that represents an external reference (xref) or a custom object from another application. It acts as a placeholder for the actual object, allowing you to view and manipulate it without actually loading the original source file or application.
Why Use Proxy Objects?
Proxy objects are particularly useful when working with large and complex drawings that contain multiple references or custom objects. By using proxy objects, you can reduce the file size and improve performance since the actual data is not loaded into your drawing until it is needed. This can be especially helpful when collaborating with others or when working on projects with limited system resources.
Types of Proxy Objects
There are two main types of proxy objects in AutoCAD:
- Xref Proxy Objects: When an external reference (xref) is attached to a drawing, it can be represented by a proxy object. This allows you to view and modify the xrefed content without loading the entire source file.
Xref proxy objects also maintain a link to their original file, so any changes made to the source will be reflected in your drawing.
- Custom Proxy Objects: Some applications allow you to create custom objects that can be inserted into AutoCAD drawings. These custom objects are represented by proxy objects in AutoCAD, allowing you to work with them as if they were native AutoCAD entities. However, keep in mind that certain features or properties of the original object may not be fully supported.
Working with Proxy Objects
To work with proxy objects in AutoCAD, follow these steps:
Loading Proxy Objects:
To load proxy objects from an external reference (xref), use the XREF command. This will bring in the geometry and other data from the referenced file, allowing you to work with it as if it were part of your current drawing.
Modifying Proxy Objects:
Proxy objects can be modified using standard AutoCAD editing commands. You can move, rotate, scale, or modify their properties just like any other object in your drawing. Any changes made to a proxy object will be saved within your drawing and will not affect the original source file.
Updating Proxy Objects:
If an xrefed file or custom object has been modified outside of your current drawing, you can update the proxy objects to reflect those changes. Use the XREF command and select the option to reload or repath the xrefed file. AutoCAD will then update the proxy objects accordingly.
Conclusion
Proxy objects in AutoCAD provide a convenient way to work with external references and custom objects without loading their complete data. They help improve performance, reduce file size, and facilitate collaboration. By understanding how to use and manipulate proxy objects, you can enhance your workflow when working with complex drawings.
