2011- Flat pattern shows as "Hidden line" layer

[karthur1]

When we open some of our idw that have flat patterns shown in them, all flat pattern edges will be on the "Hidden Lines" layer.  These were created in 2010 and migrated to 2011.  We have came across several of these and some of them can be "Fixed" by editing the flat pattern definition (see this link below), but some of them can't.  Sometimes we have to delete the flat pattern in the idw, reinsert it and redo the dimensions.

What is the fix for this?

I'm having the same problem intermittently, so I'll bump this thread hoping a solution is out there.

Jonathan,

Just wondering if you were able to "edit flat pattern definition" and get it to show correctly?  I know it is frustrating to have to do this.

Hey Kirk,

I watched your video, and my problem is the same as yours. It can be remedied the same way (Editing the flat pattern), but is frustrating.

Yea, its great to be paying so much for should a great program that only works sometimes OH, i mean PAYING EVERY YEAR............and after years and years of the same problem the only fix is a "work-around"

Hi! The behavior does not sound right to me. It is possible these flat patterns were created before 3D flat pattern was available. Do you have an example showing the behavior? I would like to understand it better.

Many thanks!

[andrecok]

this is REALLY BORING! sometimes it works, wometimes not. costs a lot, soon much more, but bugs are unsolved since the age of dinosaur. customers as BETA-tester.

[johnsonshiue]

Hi! Could you share an example exhibiting the behavior? The behavior certainly is wrong but I need to understand why and how it happens. Please send it to me directly (johnson.shiue@autodesk.com). Without an example, there isn't much I can do.

Many thanks!

Johnson,

How about this?  Open the idw and you should see the issue.  To correct it, edit the flat pattern definition in the part.  Flip the "Base Face" a couple times then exit and return to the idw.

I can probably come up with more examples if you need them.  I think these files were created with 2017.  Not sure how the flat pattern gets into this state.

Hi Kirk,

Many thanks for the example! I was not aware of this issue. There is something interesting about the flat pattern body. Somehow the body is being considered as hidden edges and the edges are on Hidden Edges layer. I need to understand this behavior better.

Thanks again!

[karthur1]

Thanks, I'll ask around and see if I can find more examples.

Has this issue been resolved? I'm having the same trouble with 2017.

[karthur1]

I haven't ran across it in a while.  But ..... it may still be around.  We are on 2018 now.  

Can you post an example?

Thanks

[timothy_berg]

Sure can, the most frustrating thing about this is, this issue is not consistent. I can place a dozen flat patterns and than one will be on the wrong layer.

Thanks for your help

Just curious if a Rebuild All resolves this, as described here:

https://forums.autodesk.com/t5/inventor-forum/sheet-metal-flat-patterns-appear-as-dashed-lines-in-id...

I just ran into this issue Inventor 2017, and rebuild all resolved it.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Is that accessible under ilogic?

Hey, no fair answering a question with another question. 

So can I assume Rebuild All does resolve this for you then? (just wanting to know for my own knowledge)

But yes, you can run something like the snippet below from the drawing to rebuild the model and update the impacted drawing views.

edit: I just ran this snippet on karthur1's files from post #9 of this thread and it fixed the drawing view.

I hope this helps.

When trying to click the command "Manage -> Rebuild All", the line type of flat pattern view turns correct, which works fine in Inventor 2018 even in Inventor 2017 with Update. Does it works fine for you?

[karthur1]

River,

I opened my two sample parts posted above that is showing this flat pattern wrong in the idw and did a "Rebuild all".  The flat pattern lines are shown correctly again. I am currently using 2018.2.3.  Wish we didn't have to do that extra step, but if that is what fixes it, then I guess that is good enough.

Thanks,

Kirk
