When a client is unable to open drawings after receiving a transmittal, the most likely mistake made by the CAD designer would be related to the management of external references, commonly known as Xrefs. If the designer did not bind or attach all external references within the drawing file, it can lead to missing elements when the client tries to open the drawing.

When Xrefs are not properly managed, the main drawing file may reference external files that the client does not have access to, which can result in broken links and missing context in the drawing. Binding Xrefs integrates them into the main drawing file, ensuring that the client receives everything necessary to open and view the file as intended.

This technique is crucial for maintaining file integrity and allowing seamless collaboration across different environments, as external references might not be in the same folders or accessible to the client. Therefore, ensuring that all external references are correctly bound, thereby making them part of the drawing, is a critical step in the transmittal process to avoid access issues on the client's end.
