Removing edge blends with lost references 1

When creating complicated castings, we often get the lots of edge blends where the edges have been consumed by another feature or similar and our part navigator ends up with lots of warning triangles on those specific blends. Other than editing each edge blend separately and clicking the delete button inside the command, is there a way of deletin these enmasse? Using a journal perhpas? I thought part clean up might do it, but it doesn't.

Cheers

Si

Hi JCBCAD,
i was just wondering if you can use CheckMate (Buried Features check)results (Visual Reporting) to filter all these blends and then delete it in one shot (right click the top-node of the reult and selecting SELECT ASSOCIATED OBJECTS and delete it).
Or maybe using FILTER SETTINGS in part navigator to filter down features " features with warning" and then delete them.

JBCAD Did you ever find a good solution to this question? Thanks

Nothing other that what you see here.

Happy New Year :)

Using selection intent (tangent curves, connected curves, face edges etc) instead of selecting multiple edges would minimise the number of consumed edges, although the feature would fail if the seed edge is consumed upon editing.

It's fixed in NX9, it basically deletes any lost edges for you :)

Thanks gives us another reason to push for upgrading to NX 9 in spring time.

Hi Simon,
I'm testing NX9 and I don't find this fix.
Is it an information arrived from SIEMENS or have you tested personally ?

Thank you...

I get this error Cowski.

I should have mentioned that I tested it on NX 8.5. "SetEditWithRollbackFeature" is new to NX 8, I'll see if there is an alternative to use in NX 7.5...

This works great. Slow to rebuild the model but it could be an issue with my model. Nice One hundered stars to Coswki.

It looks for blends with missing references, if these occur early in the file it will essentially rebuild the entire solid. On large files, this can be a long process.
