Dear all,
you for sure would not believe, what I tried in the meantime, to get clean SVG out of SU7 FREE. Call me beeing stupid.
All attempts, getting clean SVG out of FREE, including using an EMF (Enhanced Meta File) printer drivers, failed in some or the other way.
My last resort was to ask Google for a PDF export even in the FREE version. Just sent, if they answer, I'll report.
Best regards, deerwood
