I believe this to be a problem with Epson printers and perhaps with all printers setting up custom page sizes. This has happen with VW 8, 8.5, 9 when using the Epson Large Format Printers (1200 series). You have to be extremely careful when you define your custom page size, ie. 11x17, 13x19 for example. And it can be further complicated since Epson gives no clue how to do this. The problem has to do with the fact that the true size of the print is not the same as the name size After defining the custom page size in Page Set Up--go to Page--Set Print Area--go to One Page and note the true size that VW designates. Your drawing must then be multiples of the height and width measurement indicated. Good Luck

But why do they fail? Anyone have background on this? Or is there a tech note that deals with it that I have not been able to find?

I have had considerable difficulty with what the program classifies as "failed additions". I created scaffolding units consisting of tubular piping ( extrudes ) which were then joined with both unedited and subtracted pieces which were then completed by the addition command. After saving and reopening -some - but not all -of the units have "exploded" into boxes. If I then select each box and "ungroup" most will revert to their pre addition state. If I figure out why--I'll post.
