vanishing lines

When I insert an assembly into a .drw, somelines disappear when I use the (no hidden) in the "view display". How doI correct this?
 
I have experienced the same where a small curve is missing. Also I have had the exact opposite problem. I can't get rid of some "hidden" lines from an assembly drawing. I had to resort to using white out on the printout. Are these two functions possibly related?

I believe you both have interference in your assemblies. Pro/E can not do hidden lines correctly if two parts occupy the same space.
 
In my case there is adifference of 0.014mm between the OD and ID of the parts and the curve on the LH side is part of the main wire as a Protrusion with trajectory and sketched section.
 
I teach ProE at the college level and I've had a couple of students encounter this same issue. Thank you for the fix!
 
Did I miss something? I have a component clearance of 0.014mm meaning that dr_gallup's suggested cause does not seem to be applicable in this case. Is there any other possible cause?
 
Nothing missed. There just aren't any other blanket offerings.
Guesswork from here on out and looking at a pic isn't going to help.
That's the kind of thing you have to monkey-with-football it thru.
Things I'd look at ...
Accuracy.
Geom chks.
Hide a comp.
Try a general view vs. the broken view.

A couple of things (none that are nice to do)


1. I have had a similar problem and it turned out that the graphics card I had at the time (6/7 years ago now) was basically underspec'd and with large/complex assembly drawings, lines appeared and disappeared randomly.


2.One way I have found to try and debug the issue (and I know this is time consuming) was to create a simp rep (that you use as your drawing view) and add/subtract features/components until you find which one is the problem.


Best of luck

Thanks prohammy,


I will try anything once at this stage.


If and when I have conclusive evidence of the cause, I will try to post it.
 
Make sure it's not a surface if so hide hidden quilts. If you have .014 clearing bump it up to .05 just to test.
