Rolled Blend on Sharp Edge

[roseda]

Is there a way to create the type of blend shown in the picture below without adding a small blend to the vertical edge?

On the (vertical) corner edge that the blend rolls over make that a very tiny blend, maybe one-thousandth of a unit, and then create the fillet with tangent edges "on".

As has already been alluded to, by both YOU and jerry1423 there is no way to create that sort of corner blend using only the blend tool. Now if you absolutely must avoid using the very small blend workaround, then you will need to construct the feature using other tools.

What version of NX are you using? Perhaps I could you at least some sort of workaround.

I noticed this lack of functionality when I began using UG version NX3. I wonder how did Solidworks developers implement this feature using Parasolid geometry kernel? Attached are images from Solidworks. It can be done in Catia as well but Catia doesn't use Parasolid kernel. I hope someday NX offers this functionality.

Attached is an NX 9.0 example of about the best that you can do in NX at the moment.

Thanks for the work around John.

It would be good to implement it in a future version of NX unless it's patented by Dassault.

Roseda, here's how it works;
If you find an option which you think is missing, or a function/ feature which could be enhanced.
You go :

http://www.plm.automation.siemens.com/en_us/support/gtac/

then select either "Contact Support- Gtac operating hours and phone menu"
( or "Gtac Country Websites" for non-US users.)
OR
"Create or Update an IR"

When filing Enhancement Requests ( this will in Siemens vocabulary be an "ER") Remember to motivate why this feature/function is important and how much money you would save if it existed.
Siemens development must for each new release decide which new features / functions to spend their development budget on.
They have a very long list of possible enhancements, features requested by the users, features that competitors have, features needed because of future projects etc etc. All projects have a cost.
No features are today implemented just for fun, they must all be motivated.

Posting good ideas on forums like this, might not result in much more than a post on a forum.

Serious question.

Besides aesthetic reasons, whats the advantage to the radius on the corner?

@robnewcomb
Simple answer.
It is not about aesthetics. It produces a better design.

@cnc07

if I was machining that condition, I'd just remove all the radii and use an end mill with the proper radius. The actual product would have a round corner.
I would never call myself a machinist or even a cnc machinist though I have quite a bit of background, I always think about "how would I actually make this" when I model something.

That's why I assumed it was just for aesthetic reasons.
