Issues with "no hidden" showing lines that should be hidden

[tdickson]

Hello,

I'm having an issue where I select the "no hidden" option in my drawing, but some components display as if they are in wire frame. Lines that should be hidden are not. The same issue can also be seen in the model when the view display is set to "no hidden."

Thanks in advance.

If you have interferences in your models, Creo will sometimes show hidden lines as solid.

Interference's between the two components in the assembly, or within the component itself?

2 components in an assembly. I assume it's like this post...Re: Edges disappear in drawing only your edges are showing instead of disappearing.

Another possibility is that you are using models obtained from a supplier that are not solid models. If a STEP file is read in and has non-manifold surfaces, it will just stay a surface model, and thus not behave properly in hidden line and no hidden line views.
