Duplicate a Revit Structure Gridline

We knew that Revit Structure does not allow us to created Gridlines with the same identical identity.

And so, here is the work around for creating a duplicate Gridline:
First, create any gridline.

Second, edit Gridline text by right clicking,

choose, Insert Unicode Character

then, choose LRE, Start left to right embedding,

and in this case, type "D", for us to duplicate Gridline D

And . . . . . . .there you see it. . . . two Gridline D.

This procedure is often used when there are link files to the model, and you can't manipulate

a linked gridline. . . . . .hence we duplicate gridlines . . . . enjoy.
