I had already for years this idea to make a Autodesk Inventor Add-in that can Match/Copy the "Welding Symbol" Properties in a drawing to (an)other "Welding Symbol(s)".
Since the release of Inventor 2024 the Welding Symbols are now API supported, so I could now implement my idea in form of this add-in.
I think this option would be a great benefit for many of us.
Maybe something for future releases of Autodesk Inventor.
