BIM Software Tip: How to Resolve Issues with AutoCAD Block Writing Operations Being Rejected and Proxy Objects Not Allowed to Copy
Cause:
The objects in your drawing were created using third-party applications or specialized AutoCAD vertical products that utilize custom objects. Without the appropriate local program or the installation of the corresponding object enabler, these objects cannot be copied.
Solution:
Either delete the proxy objects or install the required third-party object enabler.
Suggested Workflow to Test:
- Create a new clean drawing, for example, using the
acadiso.dwttemplate. - Insert the affected files into this clean drawing.
- Attempt to use the
COPYCLIPcommand to copy the objects.
Note: In some cases, proxy warnings might not appear. Using alternative workflows like this can help resolve the issue by detaching proxy elements from the source content into a new file.
