Generic Mass is showing Projected lines from a Sweep under it

[Anonymous]

Hello All,

I've been having this issue with a generic mass roof when viewed from far away shows lines from sweeps underneath it. I have checked to make sure all the mass materials do not have any transparency yet when viewed from afar the lines still show up. 

I'm currently in Revit 2017 has anyone else figured out how to fix this issue?

Have you tried disabling Hardware Acceleration?

Thank you for your posting @Anonymous. 

Does this only occurs when you zoom out? If this occurs also when printing, please try to print in vector.

I tried what you suggested and It did not change anything in the views that I could tell.

Yes, these lines are only shown when you are far away from the structure. Printing I am not sure, I am taking images for a walkthrough and the horizontal lines appear when not in close proximity.
