Ok, here's the issue.
I have several pipe profiles created with C3D-2016, and when I run a "Publish" on the sheets (to pdf, and it doesn't seem to matter how the publish is run), the fittings on the profiles will 'extend' to the edges of the profile view. When I run a 'Print' (same plot settings, BTW) on each sheet individually, the sheet output is correct.
Is this an issue with the printing, or with the pipe settings?
