Deleting a blend problem 1

[wadec]

Often times I'm required to modify a customers model to account for casting shrink. Sometimes this involves moving faces, I find that to get it to work I normally have to delete blends that are adjacent to the face in question first.

What happens somewhat often is I delete a blend, the operation is successful (no error and shows up on the history tree) yet the blend remains. Is this a bug? Also you can do the same command more than once with out the blend being deleted, yet the history tree keeps racking up the steps.

I'm running NX6 and the command I normaly use to delete a blend or face is under synchronous modeling, delete face.

I've attached a cut-away example..the face in question is yellow.

... the colored single blend it to complex
when you select the connected blend... and reblend
its often tricky to get the wanted result

If dealing with casting shrink, wouldn't you want to scale the entire part rather than bother with individual faces? Unless, of course, you're dealing with a finished model and you've been provided only a partial casting from the customer, which wasn't mentioned in your initial post.

I'm dealing with Titanium. It doesn't shrink uniform. IDs, OD's, heights, thicknesses etc all shrink at different rates inch per inch.

Normally what I do for a round part is scale the height at one rate and then the other 2 direction at the same rate. Then go add the additional shrink factor to either the OD's or ID's depending on which is easier.

We also have to add stock to every surface to account for contamination (chemical milling stock)

Thanks for you input.
