In some of the latest versions of the Autodesk DWF Viewer there has been a problem to plot or print centered in half scale. Typically we produce A1 DWF files but want to print them on A3 paper. Print to scale is not an option since they should be plotted to 50% scale. The drawing gets clipped only on 2 sides and not on all 4 sides. There is though a workaround in the latest Autodesk DWF Viewer 6.5 using a registry setting. So now it works to print to scale and have the margines clipped on all 4 sides.
The setting (pplsvpPlacementModifier = 1) that has worked good for me is used in this reg file. Download and run it. DWF Viewer has to be restarted.
The registry key is:
The possible values are:
0 - align the center of the physical page with the center of the virtual page [default].
1 - align the center of the printable-area of the physical page with the center of the virtual page.
2 - align the lower left corner of the physical page with the lower left corner of the virtual page.
I've also noticed that Scott Sheppard has updated his FAQ to include this tip.
