You may get a drawing with a detail title showing some values behind the coma, like example below:
In case you would like to remove values behind the coma, you just have to go to "Project data" dialog-box, and set the Precision to "0", like shown in print-screen below.
Then if you create other drawings or update existing ones (from the Document manager) you will get the wished result.
Comment: in case you have plates with e.g. a thickness of "2.5", the detail title will display "2".
