Swept blend flat pattern C channel

[RE_4329770]

Hi everyone,

Long time viewer, first time poster.

I am trying to make a chassis consisting of a swept C channel. It is consisting of a c channel changing in height but also is at an angle with reference to the original section.

While looking simple, it has me quite flustured on the correct way to perform this. Got it half way there with the swept blend feature. But I am unable to rip the walls and create a flat pattern.

How would you guys go about this? Keeping the model also simple to adjust. I am using CREO  4.0

Cheers,

Peter

Can you provide a model for us to inspect?

My favorite method is to model a solid without rounds and convert it to sheetmetal by shell then use conversion to create rips and bends.

Thanks for your reaction, attached you will find the part.

I will also try your method. Thanks!

Working with your model, I would suggest removing the bends on sharp edges from the sweep and use conversion to create the bends and rips.

Thank you for your help! I am not able to perform the conversion correctly. Are you able to create a flat pattern of this model? I have tried the shell method also, but run into the same problems. 

Cheers,

I have been able to flatten it.  To flatten it, you need to define extra deformation areas.  The other issue is creating the corner reliefs.

Here is what I have been able to do in Creo 7.0.
