Hidden Lines partial display

[Anonymous]

In a section view some hidden lines are showing and some are not. I have attached an example. Everything behind the pressurization unit should be shown as hidden, whereas some pipes are showing correctly (hidden) and some not (still showing as a solid linetype).

Does anyone know a reason for this?

Thanks.

MEP Hidden lines have a relatively low priority in the "Graphical Overrides Hierarchy", so there are a number couple of possible causes.

- Check the element's Phase settings; it might be overridden by Phase Graphic Overrides.

- If the System Graphic Overrides is assigning a Line Pattern, it will trump MEP Hidden Lines.

- Is there a View Filter affecting these particular elements?

- Low chances, but the elements may have been overridden "by element". If the View is duplicated, does it appear correctly?

Corey, thanks the solution was your:

- If the System Graphic Overrides is assigning a Line Pattern, it will trump MEP Hidden Lines.

The pattern was set to solid in 'Piping System->Type Properties->Graphic Overrides->Pattern

So for each pipe type that was not displaying correctly I simply set the pattern to none and now all hidden lines display correctly.
