Lines for components dont show up

[Anonymous]

I am using pipes and pipe fittings using sysque addin, and for some reason in elevation views will show only parts of the components. Example, i have a pipe connected to a flange, with a "weld gap" put in, and the lines for half the flange, the weld, and some of the pipe is cut off/ just not visible at all. I was told by someone that it could possibly be my graphics card, but i am pretty sure what i have should be fine.
