I kept getting this error message after selecting a coupling from the prompt when connecting pipes and fitting. Could you tell me what this error means:en-USTelligent Community 12https://communities.bentley.com/thread/782264?ContentTypeID=1Mon, 18 Sep 2023 10:48:03 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:8a5ca062-6140-44e4-8d32-445f2327793bDeepak Singh<p>Hi Myra,<br /><br />I can recall this concern and this is a bug in the shipped application. However, you can customize the schema to get rid from this error message.<br /><br />You need to add SPECIFICATION property to CAM_AND_GROOVE_COUPLING class or from the JOINT class CAM_AND_GROOVE_COUPLING you can remove the SPECIFICATION attribute to check, if you don&#39;t want SPECIFICATION to be check for the connection.<br /><br />Regards<br />Deepak Singh</p><div style="clear:both;"></div>
