Bug [print dialog]: line width change not preserved and not consistent


#1

This appears to be a bug but if there is a workaround I would love to know!

In Print->Linetypes and Line Widths I changed the line width from hairline to .50mm which only changed the printed line widths of a few random lines (mostly dimension lines and one or two curves - but not all curves.)
I tried changing the line width back to ‘hairline’ without success. The line width is now permanently stuck to .50mm. Now printing is essentially useless.
Changing the line thickness number in PrintDisplay does nothing. (This number doesn’t seem to correspond to any particular measurement system. The default is 40 but I can’t figure out in what kind of unit that is referring to.)

thanks,

Steps to hopefully reproduce (same for Rhino 5.3.1 and RhinoWIP):
In the print dialog change the line width to .50mm.
Print.
Printed line widths seemingly random between .50mm and hairline.
Set line width back to ‘hairline’.
Print. No change in print output.
Back to print dialog, line width still mysteriously set to .50mm
No amount of changing back to ‘hairline’ or any other width makes a difference.

PS. It would be great if line widths could be set in points as well as mm.

PrintDisplay defines the appearance of your model on screen. From the help file: Thickness
Defines a screen resolution to multiply object’s Print Width.
I read that as the print width in pixels.

In the Print>Linetypes and Line widths however, the default line width is the line width that will be used for all curves for which the Print Width property is specified as “Default”, either by layer or as a custom value. Any other value will override the default width.

Thanks for the clarification Max.

The Linetypes and Line Widths are still stuck at .50mm though and any
changes have no effect and are not persistent (the dialog always reverts
back to .50mm.) I suspect that there is something is corrupted with the way
preferences are stored on my system. Can you tell me where the preferences
are stored so that I can try restoring everything to the defaults?

thanks,

Hi Claude,

I am not really knowledgable on how things work behind the screen, but here is a link on how to reset (all) your preferences to default: https://wiki.mcneel.com/rhino/mac/resetprefs I am not sure if print settings are in there somewhere though.
