Add 3' of stone to existing vertical siding

[Kbird]

Have a look in the HD Pro Data Folder , there is a Folder Called Archives , which are the Auto backups of the plans you have worked on , and see if one of them is old enough to eliminate the issue without have to redraw too much.

some other thoughts...

did you check the default materials on each 1/2 of the wall , in the materials tab of the dbx are correct ? see the lower part of this KB Article:

DJP , may be more help , ask him if he'll look at your plan as he has lots of knowledge and just about all versions of the software so can open your file, he maybe able to figure it out , as I'm not sure how working on roof planes would effect Pony Walls......it may not be the real cause though.
