I am using STAAD.Pro 2004 Build 1004.US also known as the second edition. When I try to add plates using the new feature in the Geometry menu called "Create infill plates", I encounter the message "No closed polygon found to fill in with plates, please check beam selection".What am I doing wrong?
This was an in build 1004 and has been rectified in the US Build 1005. If you need to use build 1004, you can use the same facility from its icon which is shown below.
