Boundary blend surfaces in Sheetmetal module

[mms-2]

Hi Friends,

my query is in sheetmetal module,

while creating the complex sheetmetal parts, we use sufrace options (boundary blend etc) and convert that as a first wall. And then the flat pattern option is clicked all other bends except the boundary blend region unbends. is there any option to flatten those bends in pro e ? (since the sheet metal part is accepted as a first wall, why its not unbend ?)

In our firm we use a third party software to flatten such complex shaped sheetmetal parts.

Welcome to the forum, Mahesh.

Sheetlmetal doesn't do unfolding deformations as a rule. It can flatten form features, but these have no intelligence when it comes to flat patterns.

The only way I know to flatten complex surfaces is Flatten Quilt. Of course, if this is your 1st sheetmetal feature, this doesn't do you a whole lot of good.

I can understand how you might want to flat pattern complex stampings. And Creo can do a lot a very specific things. But it has to to know what to do when creating the flat pattern. You can define deformations and shears or manage the specific regions in the flat pettern. You will want to get some in depth training on this from PTC. Somewhere these is a demo of how to unfold a toaster shell, for instance.

You can try this one for a quick reference... and there is a lot more free videos at this site.

Hi Friend,

Thanks for your reply, i learned a new option by the way..

I tried the Flatten quilt option but that generates a developement of the quilt without considering the sheetmetal bending laws, I could see an irregular edge for the walls. may be this opton provides an idea of how the flat pattern will be, but not the perfect one.

I am not seeing how you are using the boundary blend so it is hard to commend more specifically.

You can use flatten quilt by 1st offsetting a quilt to allow for the bend factor. However, even that is somewhat specific about how tight you are making the bend. Sheetmetal is such a magical material
