Edges Disappeare on Interference Fit

We are currently using SW 2008. When I have a part with aninterference fit like a pem that is pushed into a sheetmetal part,the edges of the pem wher it comes through the part will not showup in the drawing. This also hapens if one part of an assebly istouching another part. The edge where they touch will not show upin the drawing. I have checked the view properties and made surethere are no hidden lines so I know that is not the problem. I havealso checked the show tangent lines option. Has anyone else seenthis issue? Any sugestions?

Thanks
