Hi,
I have question, how do you blend - which technic do you use to solve a problem like in the attached picture -tia
regards

RE: best practice advice blending

Just looking at the picture it's kind of hard to tell what's up.  May I suggest that you chop-out that piece and upload and I'll that a look.  If you can't load the entire part than just create a block which 'swallows the pictured corner of your mode and perform an...

Insert -> Combine -> Intersect...

...operation selecting both your model and the block.  Now either export the model as a Parasolid model and upload it, or go to...

Edit -> Feature -> Remove Parameters...

...blow away the features and upload that model.

To an Engineer, the glass is twice as big as it needs to be.
 

RE: best practice advice blending

Actually, it works with a .0001 blend radius, and I wouldn't even call that cheating.

uwam2ie, what version of NX are you running?

RE: best practice advice blending

And if you did do as mmauldin suggested, which BTW is one of the 'tricks' we recommend in situations like this were you're attempting to 'roll' a blend over what is in reality a 'sharp' edge, but you really need for that edge to have remained 'sharp', you could take mmauldin's model and export it out using the 'Heal Geometry' function and REMOVE all of those 'tiny' faces and still leave the blends behind.  The model will be valid, just that the tiny little 0.0001 blends will be gone, replaced by new 'sharp' edges.

I'm using Nx7.5.4 but nx 6.0 where also ok
thx

RE: best practice advice blending

Blend the "outies" first, the ones your "innie" blends are going to cross over.  

RE: best practice advice blending

And in NX 8.0 we have given you a new Synchronous Modeling operation which will allow you to SWITCH the order of blends which cross, irrespective of the order you originally created those blend features in or even if they're actually blend features.

RE: best practice advice blending

I also recommend the use of variable blend points in cases like that
