Edge Deselection in NX5
Edge Deselection in NX5
(OP)
I'm using Edit w/Rollback to edit my blends. The problem is that when I hold shift and deselect an edge from the blend operation, it deselects the entire blend. If I wait for QuickPick, it shows 2 options: All of intent, and Edge. Is there any way I can get them reversed so that the single edge has priority in the quickpick menu? Or am I missing something else entirely on how to do this?

RE: Edge Deselection in NX5
it has probably to do with the selection Intent, if you apply a blend the standard setting is Tangent Curves. So if you select one edge NX will search for tangent edges to blend. Same with deselecting edge, standard setting is Tangent Curves, if you change it into Single curve you get what you want.
Kind regards,

Interesting answer! I have always wondered that when you select by one technique like all in face or the tangent edge chaining technique that you cannot then change the method to single in order to allow you to shift deselect a few individual edges. You can do this if you use a rectangular selection or lasso method in some dialogs but not others. Obviously I'd wish for consistency and maximum flexibility at all times.

RE: Edge Deselection in NX5
As a little test of these concepts, do the following:
Create a Block.
Add an Offset Face feature with the Selection Intent option set to 'Body Faces' and then selecting the Block.
Add an Edge Blend to the resulting solid.
Reorder the Edge Blend so that it's BEFORE the Offset Face feature and note the results.
Now repeat this test following the slightly modified procedure outlined below:
Create a Block.
Add an Offset Face feature with the Selection Intent option set to 'Single Face' and then using the 'Select All' method to select all of the faces of the Block.
Add an Edge Blend to the resulting solid.
Reorder the Edge Blend so that it's BEFORE the Offset Face feature and note the results.
That should be sufficient demonstration of the difference between an 'Intent' and a 'Method'

I didn't quite follow the meaning in your instructions of the sentence.
Add an Offset Face feature with the Selection Intent option set to 'Single Face' and then using the 'Select All' method to select all of the faces of the Block.
Is that two offset features or one? Anyway of the later result is meant to be that the blend fails when re-ordered than maybe I'm seeing something that might be relevant.
I think the better example of how I appreciate the retention of intent is with a blend propagating along tangent edges. If underlying geometry changes so that the chain is comprised of what would be a greater number of single edge elements and yet knowing the intent the system reapplies the chaining logic without requiring user input.
The case I was speaking to nevertheless prefers that the selection method where necessary could be available without exclusively having being locked into maintaining the inetnt. In other words if ever I could set the intent to single edge and yet have all the bulk selection techniques available so that the workflow is far easier then I'd consider that saving in mouse clicks worthwhile. That's why the example I give says you bulk select to begin with then exclude the one or two elements excess to your requirement. There are plenty of examples where the number edges in a face that I do want to blend are significantly larger than those which I do not.

BTW, I was going to use the Tangent Edge example but I was looking for something which would actually FAIL (extra points for drama).
As for 'having your cake and eating it to', it would be tricky to somehow selectively decide when to honor the 'intent' and when not to.

The fact is that when it comes to cases where I am forced to individually select a great many items it is easy to forget the balance of those pros and cons and simply wish for an extra slice of cake.
