Assembly Inverted & Transparent

Assembly Inverted & Transparent

(OP)
I'm working in SW2010 (yes, I know its 2017) on a PC configuration that's been quite stable for the last few years. I've been working on an assembly for the last month or so. Tonight that assembly crashed in some fashion. As it did so I checked other parts and assemblies I have open in SW and they behaved fine. Only the one assembly was frozen. I closed that assembly and then made a bad choice - I saved that failing assembly during the close. When I reopened it the first thing I noticed is that it opened upside down and zoomed out quite a bit. After spinning it upright and zooming in I saw that everything in the assembly is partially transparent, kind of like what you get with in context editing but not quite the same. And right - left are now reversed. Everything else in that model seems to work. Other open models / windows are unaffected. Subassemblies of the problem assembly look good in other windows. I've restarted SW and restarted the computer. I've read this thread on a similar sounding issue but couldn't get any relief from it - http://www.eng-tips.com/viewthread.cfm?qid=50496 Does anyone know what mode or alternate universe I'm in? I've attached a screen shot.

RE: Assembly Inverted & Transparent

It would help to see the FeatureManager for this file.

What about selecting the top of the file in the FM and toggling the Transparent setting?

How about doing a Save As to a new (and temporary) assembly name and seeing how that turns out?

Hi updraft. Thanks for jumping in. A shot of the feature manager tree is attached. It is of a saved under a new name and renamed model (which looks the same). I toggled transparent on and off and other than the icon showing that it was in this state or that state there was no change, no change to the way the model was displayed.

RE: Assembly Inverted & Transparent

Do any of the parts display correctly?

Can you suppress all but one part and see if that makes a difference?

On a probably unrelated but possibly not note, there are an awful lot of fully modeled threads in there, you may want to remove some of the detail and just model them at major/minor diameter.

Hendersdc-

It appears that none of the components display correctly, at least if going by what seems to be true that the lightest colored ones (of which there are few) can't be seen through because of their color (black is more transparent than white in this inverted world I'm in). I've now not only suppressed all but one part but actually deleted all but one part (from the "saved under a different name and opened" file that Updraft suggested), that part is a catalog item that I downloaded from my best friend McMaster. Regarding the anatomically correct threads, they come with the fasteners I've downloaded from McMaster. I don't think there is an easy way to remove them other than to do a partial remodel of each fastener type.?. But in any case nowhere near the number of fasteners in this model than I've had before and no changes in fastener content in the days leading up to the problem I'm having. New observation: when I select a part instead of turning blue as is the usual on my system the parts turn to a (mostly) wireframe representation other than a few of the back side faces which don't change.

RE: Assembly Inverted & Transparent

(OP)
I just tried an experiment or two - I opened a new assembly and brought in the troublesome assembly (the copy file which is now pared down to one part). Everything appears and behaves normally. Then I inserted a small assembly that has handedness, inserted at the top level. There is no RH-LH reversal. Then I inserted that same handed subassembly directly into the troublesome assembly. When viewed from the troublesome assembly that inserted subassembly is reversed. When viewed from the new assembly its correct.

RE: Assembly Inverted & Transparent

Unfortunately sometimes the best solution is to just recreate things and write off the old file as corrupt, it sounds like that might be the case here.

RE: Assembly Inverted & Transparent

(OP)
Agree - I came to that conclusion also, but kept this open hoping to learn something. Its really just a collection of 10 or so un-corrupted subassemblies mated together, maybe 2 hours of work to recreate or 2 hours of improvements since the last good backup save under a different name.
