PTC Thumbnailworker prefers DWG over PDF in representation
I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.2.1
We have a representation on an EPMDocument published with a custom AutoCAD Worker. The publishing works flawless, but since customer needs DWG in representation (beside the published PDF) we found that the PTC ThumbnailWorker prefers the DWG for thumbnailing over the (monochrome) PDF which results in coloured PDFs.
Do you have any advise to get the PTC (OOTB) ThumbnailWorker to use the PDF (instead of the native DWG in representation) for creating thumbnails?
