Hello,
We uniformed our most used libraries by exporting the libs with the
LibDevToolkit to XML and finding/replacing parameter values there with BBedit on Mac.
The tool is quite straightforward if You have done any programming before.
It took one work day for one person to do the job, but think it paid itself back very soon as we had around 25 persons tweaking the parameters.
Should have done the job quicker, but I uniformed some parameters (not only values) as well and had to do it carefully.
Uniforming is an efficient way to get the line weights correct on the first printing as well.
