Surface desing- smooth radius corner

[T_F]

It should be possible to generate corner radius, like the image bellow.

At the moment creo has the ability to generate a corner sphere radius. But it should be usefull to generate a simillar quality radius setback.

for the ones who works in metal stamping industries, will understand this need. This is very usefull, to prevent cracks in metal stamping parts. Solidworks, solidedge, CATIA, NX, Inventor has this feature. The solution provided by CREO isn't the best solution for this type of corners. Please take a look deeply in this enhancement.

Once again.

I have this surface:

And I need to draw the following.

Still no way of how to do it.

You might be able to create the geometry in the forming tool (die etc.). That's a weird looking blend, I've never seen anything like it, but then I'm not an expert sheet metal guy. Best of luck!

[T_F]

Do you have any suggestion?

"You might be able to create the geometry in the forming tool (die etc.)."

[AB_9239964]

Try looking at the picture I posted and do that transition radius on your tool. I haven't played much with sheet metal dies/forms, but I think that'd be the way you'd want to go. There are some experts here.

Sorry, I can't find your picture, can you tell me where it is?

We complained about this issue also in other suggestions/ideas. Having a better transition to corner edges is a must in your modelling strategies. We don’t develop product, we only design/produce stamping tools, and we can’t impose the limited corner sphere transition that simply doesn’t work in most cases.

In this picture there’s a simple Catia automotive part (the cad system used to develop the majority of automotive body parts), the transitions are smooth and simple but we can’t replicate them with any radius transition solution in Creo.

PTC should address this issue with more care and more proactivity.

[AB_9239964]

As I understand it Catia is WAY more expensive, so, you can't certain features in a lower-priced CAD package.

[T_F]

You are right, but you need to explain me also, how even smaller budget CAD tools, like solidworks, solidedge, inventor, are able to create this within radius command??? So if the lower and the high end CAD packages have the hability for this, why the Middle one don't. It simply don't make any sense!

Inventor costs nearly half of CREO

Creo has had it for many years. You have to go into "Transition Mode" and pick "Corner sphere". Then drag the handle, and then you get 3 other handles you can drag.

[T_F]

The transition mode from CREO, don't produce simillar results, and most of the times it simply doesn't work. If there is edges with length smaller than the length needed for the sphere, it doesn't create. So it's useless!

[AB_9239964]

...sure...if you say so.
