To fix a problem with plotting to PDF (see our blog) with the new DWG to PDF pc3 file Autodesk has enabled a new setting or command.
When plotting to PDF all SHX text became "Comments" that are visible and searchable in the PDF. This caused some problems for many and wanted a way to exclude the text from the comments.
In sp1 we now have a way to turn it off. Set EPDFSHX=0.
From the Readme:
When plotting PDF files, SHX text in PDF comments can be turned off by setting EPDFSHX=0 (the default is 1). In addition, some PDF viewers display text that uses SHX fonts as comments and this system variable addresses this issue as well. In a future release, we plan to rename this system variable to begin with the letters PDF.
To obtain the service pack:
While it really isn't a problem, it does give us more control over this new feature in the updated dwg2pdf.pc3!
