Won't flatten correctly

I am not sure why it will not flatten the two overall flanges on each side of the flace?

 

I tested it out and one side works but when the 2nd side is added it gives it trouble.


Triangle faces are same size but on opposite ends.

If I cheat and add a flange and then cut it as a triangle it works.

 

I can't do the[draw tringle-->face-->draw line--> fold command ]on the other flange then it gives me trouble

Flattens here no problem, I am on IV2014 so I can't send you the file. Check that you are current on all SP's for your version. I just deleted the existing Flat Pattern in the model browser and ran the Flat-Pattern command again.

Before I spend any time on this - are you absolutely sure the folded result is what you want (when I dimension a drawing of the part - some of the dimensions don't make logical sense to me).

Work has been done on the "Unfolder" in the last couple of releases of Inventor. Since the change to this new forum format I an unable to attach files or I would post the flat pattern picture.

I don't care about the flat pattern at this point.
When I dimension your folded part - the dimensions do not make logical sense to me.

In other words, I don't think the part is what you really want before even beginning to worry about finding a technique that will flatten in your release of Inventor.

In IV2014, just deleted the existing Flat-Pattern and ran the Flat-Pattern:

Has to do with this corner Inventor 2014 has been fixed so it works but in 2012 it cannot do this corner without a relief of some type in the corner.

 

  Here is the part with that relief and you can now unfold it..

 Now if you don't want the relief in the part just and a filler in the flat pattern I did one side in flat pattern so you can see..

I attached one more version.

 

My concern is I do the same exact thing for both sides. The only difference is on opposite of the  XZ plane.

 

I can FLAT PATTERN my model. Except if I bring the EOF marker past the last fold03 on the opposite side then it does not fully flat pattern it for me. Maybe 2014..? Why should I have to do play around with my commands to solve this unless it is a 2012 to 2014 issue?

 

 

Jletcher: "Has to do with this corner Inventor 2014 has been fixed so it works but in 2012 it cannot do this corner without a relief of some type in the corner."

 

Update:

Hmm ok so if I add a relief(small) to the other face it probably will work and thats 2012! 2014 solves this. OK I will OK solution if a few....
