The latest V6 Service Release Candidate installed today appears to have introduced a printing problem. When printing Layout pages, some rendered images are ony partially displayed in the output PDF. I normally use Rhino PDF as the driver, but I have also tried PDF Creator, and the problem persists. I also tried Google Chrome as the Viewer instead of Acrobat Reader, and that demonstrates that it is a file creation problem, not a viewing problem.

I closed Rhino and restarted it to recreate the pdf with Rhino PDF. This time the pdf output was correct. I have seen the problem a few times today, but not on every print operation.

These are the faulty images:

This is what should have been displayed:

Hi Garry - if possible can you please saveSmall, zip, and upload the file here:

to my attention.

Hi Pascal. I have uploaded the files. I deleted many layers to reduce the file size. There are 2 pdf files, one with the correct images amd one with the problem. The problems are on pages 7, 9 and 10. Both pdf files were produced from the same model, pointing to an intermittent gremlin. I know that you love such issues. Happy hunting.

Regards, Garry.

Hi Garry - thanks, I get the good version, at least for now, of the print - do you have any idea whether this is more likely to happen if the file has been open a while, or worked on a bunch?
when it goes wrong next, can you try a ViewCpatureToFile and see if that also looks incorrect?

-Pascal

Hi Pascal. I starteded Rhino, printed OK, clicked the Perspective view tab, then reprinted and the problem was there again. No changes were applied.

I am printing by right clicking the Page 1 tab, and specifying pages 1-10.

ViewCpatureToFile appears to be OK.

I then printed about 6 more times with the model still open, and each print was OK.

I then closed Rhino and restarted. Print 1 was OK. Switched to Perspective. Print 2 had the problem. I checked the Layout pages in the model and they were correctly displayed.

Once again, I then closed Rhino and restarted. This time instead of starting the Print operation from Page 1, I right clicked Page 9. It was correctly displayed on the screen. Print 1 was OK. I clicked Perspective, then started the Print again from Page 9. This time the PDF output had the problem on Pages 7 and 10, but Page 9 was OK. Perhaps the problem lies in the screen rendering, not the Print operation. The difficulty is that when printing multiple pages, I cannot see the screen display of all pages prior to printing. I hope that helps.

Regards, Garry.

Got it! thanks for the details - right now, it looks like the click in Perspective is the bad thing.
