I have problems since every time they are separate elements (beams and&nbsp;floor) I get a warning message. There is some possibility of eliminating those warning messages or that only the join action is done among the nearby elements. I want to avoid that messages.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Join floor and structural framing.PNG" style="width: 582px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/488512i715C8B1EC5AE6547/image-dimensions/582x494?v=v2" width="582" height="494" role="button" title="Join floor and structural framing.PNG" alt="Join floor and structural framing.PNG" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="message.PNG" style="width: 547px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/488513i1325B7CB15EA0F53/image-size/large?v=v2&amp;px=999" role="button" title="message.PNG" alt="message.PNG" /></span></P> Fri, 13 Apr 2018 17:00:57 GMT https://forums.autodesk.com/t5/revit-api-forum/revit-warning-message/m-p/7931459#M50840 Anonymous 2018-04-13T17:00:57Z https://forums.autodesk.com/t5/revit-api-forum/revit-warning-message/m-p/7932760#M50841 <P>You can hide the error but due to your approach it is probably telling you that you shouldn't be joining the beams of level 1 with the floors of level 2 i.e. you shouldn't be trying to join everything with everything.</P><P>&nbsp;</P><P>Would suggest instead&nbsp;you use ElementIntersectsElementFilter or other element comparisons&nbsp;in order to apply some logic to the problem of what should be joined to what.
