Proposal:
I propose that Hole and Thread Note adds variable Thread Size Value so we can output Size of thread from Thread.xlsx into Inventor drawing. The variable name can be for example <THDSZ>.
This change is very simple and straightforward, because you already have the value in Thread.xlsx in Size column.
All you need to do is output it the same way like you output for example Thread Pitch Value.
Context:
Hole and Thread note takes data from Thread.xlsx file and displays them via variables like <THDPT>.
Hole and Thread note:

Thread.xlsx

Edit Hole Note Reference page: https://help.autodesk.com/view/INVNTOR/2026/ENU/?guid=GUID-A3734FDF-FBC6-484A-B436-5938E8D90FF3
As you can see in Edit Hole Note Reference page, there is no way to input Thread Size Value.
But Thread Size is already present in Thread.xlsx in Size column.
Improvement:
This simple change would allow users to create hole annotation without pitch information more simply. There would be no need for current workaround: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-remove-the-...
