Hello Bentley, this idea is for a QR Code generator as part of the plot driver.

It can be a new string field in the .PLTCFG file, along with a new set of commands in the .PEN Design Script Engine.

In the .PLTCFG file dialog it would be a new line item called 'QR Code String'; and the value can be text string, or configuration variable or Named Expression.
These text strings are passed to the QR Code Engine and produce a QR Code in the drawing.
The size and scope of the QR Code are based on the size of the Type 6 Shape Element placed in the Sheet Model, and perhaps a minimum resolution of the PDF/Raster.

In the Design Script, as an example I use the Digital Signature logic like this. So to alter it slightly to accommodate a QRCode:

if ((type eq 6) and (color eq 4) and (level_name eq "A-SHEET-QRCODE")) then
action_item = QRCode
action_name = "QR Code"
action_type = QR_field
action_spec = QR_Code # <- This value references the .PLTCFG line item
action_range = Element_range
endif

action_string line item in the Design Script is an optional alternative to the plot config line item.
