    Refering to the post here, there are some questions on why the same tag can be assigned to two different specialty items (e.g. Strainer). 

    So here's how AutoCAD P&ID works behind the curtain. First, it checks the database and see which type of object can have a unique tag. The table it is looking for is PnPTagEnlistedColumns. If you use SQL Management Studio, this is what you will see

    Modified your P&ID or Plant 3D project configuration a lot? Plant products (AutoCAD Plant 3D and P&ID) will always cache project information locally.

  • Fixing AutoCAD Program Error

    Whenever i ran into problem with any AutoCAD software, the first thing i would NOT do is reinstall or repair the installation. Most of the time, program itself do not write changes to the Program Files, so it would be impossible for the error to be caused by corrupted installation files.
