invisible drawing views

[tmox]

i used the search in forums and FAQ's with no hits.
INV R8. .idw created from assembly, ballooned, notes etc., saved.
upon re-opening the drawing only one of six views are visible. Balloons still attached. Upon editing views can be seen as solids, but, not as drawing or hidden line views. The view that IS visible is a projection of a projection.
So OK, scrap the drawing and start over..........Not so fast. The same thing happens in a new drawing. it doesn't matter which view i start with. Soooo....tried to delete items in the assembly to find the offender. No results. Saveas new assy name. Try new drawing with the new assy........same thing. Opened design assistant to see if i got error message. everything fine.
Any help would be appreciated. This is a hot drawing with a lot of eyes watching.

I wish I could provide a better answer but I have had a similar issue and have not found a good resolution. We upgraded to IV11 and it got better but sometimes it still happens. Only on one type of assembly though, all derivatives of that assembly have similar issues. Any chance the parts used in the assembly were created in a previous version?

i re-assembled the assy with a new drawing, flipping from one screen to the other as i placed each part.
i found the offender. and the drawing views have returned now that it is deleted from the assy.
The part was a wire wrapped toroid. So, i had a circular array and an extrusion to represent the wire around half of the ring and then mirrored for the opposite side. It was the mirror that it didn't like. when i took the mirror off the part then worked again in the assembly.
At least now i can focus on my solution.
thanx

Was the part "sick", or did you just find it by trial and error?

i created a new assy and drawing placing each part in one by one working backwards by file date until i came across the offender.
i had mirrored an array in a part. I had two axis defined on the ends of the array and created a work plane across them, offset a plane to that and then mirrored the array.
the part looked fine.
when i backed up (end of part)the one axis had become 'sick' and therefore so was the workplane that was generated from it.
i deleted and replaced the axis and workplanes, all good now.
