Grid Lines Displayed when Exporting Viewport

[Brian K]

I haven't run into this issue before after using Vectorworks for some time, but all of the sudden my exported Viewports have purple grid lines behind the renderings that I can't seem to figure out how to turn off (or how they turned on to begin with). I know they've always been there but haven't shown up on my published renderings until just recently. I've tried a couple different options related to grid lines preferences but it hasn't fixed the issue. Thank you for your time and assistance.

In the Snap to grid settings turn off print and show grid.
