Sheetmetal R15 Flanges - connecting corners

[Aanu]

Hi,

I'm using Inventor 2010 and I have a problem with connecting the sheet metal corners to each other when making round radius flanges. Can you please give me a tip on how to connect the corners to each other (even though this is probably not possible in reality). Even better would be if the flat pattern of the sheet metal part would also look proper.

Note that the short edges are 90 deg bent and longer edges are 75 and 105 deg bent. This also makes creating "corner fill" parts a bit tricky.

Thanks beforehand for your answers,

Aanu, when creating sheet metal parts, the ends of flanges, and really all part edges, should be 90deg to their adjacent faces. Your extrusion10 in the model breaks this rule.  Delete extrusion10, shorten the long flanges if needed, then apply corner seams to the 4 corners.  Maybe use the linear weld trim shape option.  This should get you closer to what you want.

Hi Stephen,

I changed the corners to 90 deg which means that I need to make some changes to the main assembly which is acceptable. I also played around a bit with the corner seam tool and got close enough. Thanks for the tip.
