Does it cure it? In that case the D/W is the culprit.

I've looked at all stories, with all layers on. I've looked in 3D window with all layers. There is just nothing there. It's like a no zone zone...weird.<BR /> <BR /> Any ideas? Has anybody else experienced this?<BR /> See pic<BR /> <BR /> By-the-way, I have a work-around and that is to just make the zone boundary the polyline type and offset the edge.<BR /> <BR /> Casey</T></DIV><BR /><span class="lia-inline-image-display-wrapper" image-alt="mysterious zone boundary.png" style="width: 278px;"><img src="https://community.graphisoft.com/t5/image/serverpage/image-id/13916iEA289859FA5CFCF6/image-size/large?v=v2&amp;px=999" role="button" title="mysterious zone boundary.png" alt="mysterious zone boundary.png" /></span> Fri, 26 May 2023 12:38:38 GMT https://community.graphisoft.com/t5/Modeling/Mysterious-Zone-Boundary/m-p/203024#M109968 cgrimley 2023-05-26T12:38:38Z https://community.graphisoft.com/t5/Modeling/Mysterious-Zone-Boundary/m-p/203025#M109969 Just a thought:<BR /> What happens if you take out the Door and Window from the Wall and update Zones?
