I was editing an Autodesk Vault Professional 2012 project with an updated dataset from another company. I wanted to comment all the newly imported files globally, and had it in my head that I needed to edit it from the header, like in Autodesk AutoCAD Civil 3D. Yeah, that didn’t work. It all starts to blur together after awhile. 🙂
So the easy way to do it is simply select all the files, and edit the properties globally. After the Property Edit dialog appears, position the cursor in the desired field like Excel, and drag down to select all the remaining fields to edit globally.
