Are you using Autodesk Vault menu inside AutoCAD, to save your files?:
If not, it could be linked to Windows 7:
thanks for the answer but we don´t use Vault and the Windows help doen´t help.
i think i added a part to the 3d model from the Pipe Spec which i have before creted as an custom part. and i used the same "plantpartconvert - Object" for both, custom part and than Pipe Spec Object. Can that be the problem?
