Line weight in exported pdf is sometions wrong. Example, create a polyline closed figure and hatch it with style GRAVEL, then export to PDF. The outline line width will vary depending on the actual zoom factor of the display. I believe this bug is causing points to be displayed at various sizes in the PDF.

This task depends upon

This appears to be a problem that is unique to the "GRAVEL" pattern.

What happens is that there are point shape artifacts created along the hatch boundary when using this pattern.
If you have chosen an alternative point display mode, this can result in the effect described in the report.

No, that's a separate issue related solely to the point display modes.
This issue was caused by points created for hatch patterns which don't contain any points at all.

I first noticed this problem with the point display then found it was related to the GRAVEL pattern. The work around is to olny click PDF print when the display zoomed all the way in to some area small area of the drawing. You can veryify this bug by looking the PDF dot size when you click PDF print with the display zoomed very far out. I have only tested the linux version.

Okay thanks Andrew.
