I could give you links to some self-help troubleshooting guides but if you prefer, and are able to, it might be easiest if you could share a sample problem model that crashes your Revit 2023, so I (and others in this forum) can help you identify the root cause and help you fix it.</P> Fri, 14 Oct 2022 09:56:11 GMT esk0r 2022-10-14T09:56:11Z https://forums.autodesk.com/t5/revit-architecture-forum/fatal-error/m-p/11401476#M69474 <PRE><SPAN class="">Everything worked until Friday afternoon with REVIT 2023. Such a problem occurred on Friday afternoon. I tried to replace the 900mm door in the model with a 1000mm door and an error appeared.<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Error door_3.png" style="width: 456px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1111715iD53AFD69C6704226/image-size/large?v=v2&amp;px=999" role="button" title="Error door_3.png" alt="Error door_3.png" /></span> I tried every way. Import a new door family, then such an error occurred.<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Error door_2.png" style="width: 462px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1111716i4289B1AFB56197ED/image-size/large?v=v2&amp;px=999" role="button" title="Error door_2.png" alt="Error door_2.png" /></span> And when you press delete type, a fatal error appears and REVIT turns itself off. I can't open any old project like 2019 version. Such an error appeared<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Error dimensions.png" style="width: 460px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1111717i37A9BB94E810E1DA/image-size/large?v=v2&amp;px=999" role="button" title="Error dimensions.png" alt="Error dimensions.png" /></span> when you press cancel a fatal error massage appeared and REVIT turns itself off. You also cannot use the Split chair to cut the wall.

When I start a new project from template, I can only make a wall. No doors or windows can be added. All the same errors will appear.</SPAN></PRE> Mon, 05 Sep 2022 12:03:26 GMT https://forums.autodesk.com/t5/revit-architecture-forum/fatal-error/m-p/11401476#M69474 hanna.tammiste 2022-09-05T12:03:26Z https://forums.autodesk.com/t5/revit-architecture-forum/fatal-error/m-p/11482412#M69475 <P>Hi&nbsp;<a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/12844762">@hanna.tammiste</a>&nbsp;!<BR /><BR />From the info you provide, it sounds and looks like a family issue, maybe corrupted families in your file.
