Hi @Anonymous,

Does the same issue occur when you attempt to edit the template in one of the standard iso styles?

Thanks,

Dan

Hi @Anonymous,

Unfortunately I think you are going to need to switch to a previous "good" backup copy of the project: 

Error-Object-reference-not-set-to-an-instance-of-an-object-when-clicking-Setup-title-block-in-AutoCAD-Plant-3D

Thanks,
