testing nx9mp1

[helperug]

hello guys,
I'm testing replace feature- nx9 doesn't work as expected, or is there something I missed?
tried to replace a block feature with fillets (should transfer) to a other block feature (same topo)


sorry new in NX
regards
Erwin

When you say that it "doesn't work as expected" could be a little bit more explicit?

One thing to keep in mind, the second Block must be placed in the Part Navigator 'time-stamped' order AHEAD of the Blend features.

Note that I tested this scenario, replacing a Block feature with Edge Blends with a second Block feature, using NX 9.0.1 and it worked just fine.

thanks John for your help,
I have attached a picture, maybe a setting problem -

How did you create the original Blends? By that I mean, which 'Curve Rule' did you use when creating the Blends? When you do the Replace Feature operation the original 'Curve Rule' will be used to propagate the Blends on the new 'block'. Can you upload your part?

It worked for me with no problems whatsoever.

You do realize, don't you, that you will have to select each one of the edges that you're going to blend on the new Block as part of the workflow in the Replace Feature dialog...

I also went back and tested NX 9.0.0.19 and it worked just fine there as well.

I might be off base here, and please correct me if I'm wrong, John.....

Erwin,

When you create a new Block, you're creating new topology (faces, edges, etc.). This topology is identified separately from the original Block feature. The blend is "looking" for specific edges and adding the new topology (edges) causes the Blend to require the new edges be defined. In short, I'd expect you to be able to Replace the Block feature, but the Blend will probably fail and you'll need to redefine the Blend edges. The old edges may still show up when you edit the Blend, but clicking the X (deletes the old edge selection) and repicking all edges should get the Blend feature to update correctly on the new Block feature.

Hope this helps explain what might be going on in the background and why selecting new edges is required. Try to keep that mentality at the forefront when replacing bodies, faces, etc. It will help you diagnose model update failures and feature warning messages that might appear in the Part Navigator.

As I previously mentioned, when you replace a base feature which has other features referencing it, like the Edge Blends on this Block, whatever 'Curve Eule' or 'Body Rule' was in effect when you created the original referenced features, in this case the Edge Blends, they will be used when you perform a Replace Feature operation. For example, if the original blends had been applied using a 'Curve Rule' of 'Body Edges' then NO extra steps other then the selection of the new feature would have been needed as they would have automatically been added to all of the Body Edges on the new feature. Howeever, the example uploaded had used the 'Curve Rule' of 'Single Curve' which means that you have to explicitly select an edge for each Blend being applied. And I said, if you follow that workflow, it works just fine.

Sorry John - couldn't open his part, as we're on NX8 here, therefore couldn't see which Curve Rule he'd used. Regardless, I think we're stating pretty much the same thing for Single Curve, more or less.
