We've set up sharing and are both part of the project in A360. However when he tries to open it from revit, A360 says he isnt part of an shared projects. Is this because he has an older version of revit from the one I created the project in? (I'm running 2018, he's running 2017). Thanks.&nbsp;</P> Tue, 07 Nov 2017 19:24:39 GMT https://forums.autodesk.com/t5/revit-cloud-worksharing-forum/cloud-collaboration/m-p/7524876#M4243 Anonymous 2017-11-07T19:24:39Z https://forums.autodesk.com/t5/revit-cloud-worksharing-forum/cloud-collaboration/m-p/7525282#M4244 <P>Yes, all Collaboration for Revit users must be on the same version of Revit.&nbsp; We "hide" files of other versions&nbsp;in C4R so that there are no "mistakes" of someone upgrading the wrong file to a newer version.<BR /><BR /><BR /></P> Tue, 07 Nov 2017 21:09:59 GMT https://forums.autodesk.com/t5/revit-cloud-worksharing-forum/cloud-collaboration/m-p/7525282#M4244 scott_d_davis 2017-11-07T21:09:59Z
