Rhino v6 Polylines not showing on different views

Hi, im working on Rhino v6 and i am trying to export a make2D into Ai. However, some polylines DONT show up on the Top view, but they DO show up in a Perspective. I made sure that the lines were NOT hidden on Top view or locked, but i don’t know what is going on. It worked previously worked a few days ago, but now it is not. Thank you for any advice

A shot in the dark but do you have by any chance a clipping plane active in top view?
If this is not the case, try updating your graphic card drivers.

Hi - please run the Rhino SystemInfo command and copy-paste the result here.
