2D drawing view issue with swept trajpar wire bundle

I am using Creo6 - version: 6.0.6.0

swept wire bundle using trajpar does not show hidden lines correctly in drawing view.

I've tried changing display settings, part accuracy settings; nothing seems to fix the issue; any ideas ?

thanks

I was able to get something that works. For the trajpar feature, remove the circles representing the wires and instead, draw a line connecting the center of each of the circles, creating a triangle. Sweep this feature and then use the edges of that sweep as the trajectory for the wires. I don't know why it works but it does for me.

I am not familiar with wiring but with any solid, if you have interferences, that will cause hidden line issues on drawing/models but typically doesn't affect shaded models/drawings.

even when I confirm "no interference" still shows incorrectly in drawing views

Two thoughts:

1 Are the wires solid?, in the model, when you go to wireframe, do they show as surfaces (my color scheme shows them as magenta)

OR

2 how about interference on either end? It looks just like the typical hidden line issue for interference

I have also had issues with this when there are surfaces intersecting one another. In your case, (assuming the sketch below is correct) each wire has a shared edge (red circles) with both of its neighbors and Creo can't interpret where the shared edge belongs and likely doesn't even know the proper orientation of the surface. If you add a gap between the wires, I'm fairly confident this HLR issue will go away.

I confirmed sweep sketch has "gaps"

If the wires are tangent, that could be the problem. If they are tangent in the sweep section, then put a small gap in and see if that affects what is seen in the drawing.
