Missing lines in section cut

[JHARSH]

I use AutoCad MEP 2014. I am going through my drawing and cutting the sections and elevations I need to show. For some reason one of the sections is not showing all of the content that should be there. I have attached 2 pictures as examples of the sections that I have cut. Both of these examples are in the same drawing. Can somebody please explain to me what is happening with the section that is not showing properly. You'll see the difference when you open up the examples.

Were all these objects created in your program?

Try setting hideprecision to 1 and intersectiondisplay to 1 and facetres to between 5 and 10. The higher facetres is the more memory it uses so use the lowest you can.

Your drawing really looks like the clipping plane is into the pipe. Try moving the clipping plane back a bit. (that is, if you're using clipping planes)
