Solution for Preventing Copying of Proxy Objects in CAD
When exporting drawings in CAD, you might encounter a prompt stating that proxy objects cannot be deleted, causing the block write operation to be rejected. This occurs because the objects you want to export include proxy objects created by third-party applications or custom objects developed through CAD secondary development. If the software that created these proxy objects is not installed on your computer, these objects cannot be copied.
There are two ways to resolve this issue:
Method 1: Select the objects you want to export, enter the copylink command, then create a new CAD drawing. Choose Paste to Original Coordinates. After this, you will be able to copy or export the objects within the new drawing.
Method 2: In a newly created blank drawing, go to the menu bar and select Insert → Block (or use the insert command). Set the insertion coordinates to 0,0,0 and the scale to 1. Then browse to the folder containing the objects you want to export and insert the block.
