We are having problems with an autoCAD lt 2004 saved drawing that was edited in LT2008. When this drawing is opened in LT 2004, some of the interior walls do not display when opened in LT 2004, but they do display in LT 2008. Is there a setting or something else that can be done to address this problem?

Thanks

I will verify that, but I don't think any of the settings were changed. I am guessing that when our LT2008 was set up, there may have been some default settings that don't correspond with our LT2006 machine. The edits I made in LT2008 were adding layers, adding linework, blocks, and text, but I didn't have to change the LTscale or any other settings. The drawings we are working on come from many different architects, I wonder if linework created in versions later than LT2006 in Xref's have problems displaying in LT2006.
