Can't find symbol for specified part error

[tarrynd]

Hi There

I am using AutoCAD Plant 3D 2013. I have used the convert specs and catalogs option in the AutoCAD Plant 3D Spec editor to convert AutoPLANT specs. It is about 92% successful. My problem is that it says it has successfully brought in majority of my components, but when I try and place them into my Model I recieve and error in my command line saying "Can't find symbol for specified part error", I have exported all my specs and I have noticed this is only happening on components that are threaded/screwed components. But it is not happening to all the threaded/screwed components, some work fine. I have tried changing the location so that all my catalogs and specs sit in the "shared folder", I have tried changing the short description. I have read through all the discussion groups and I see alot on a DWG folder. But when I convert the specs there are DWG files...

If anyone has any suggestions please let me know...
