Instances not updating

[Acroloc]

At where I work we are using NX version 6.0
We machine molds w/ multiple cavities
When finish milling the sidewalls of the cavities
we usually select the surfaces of one of the cavities
then translate the toolpath to the other cavities using
transform/rectangular array/instances
this procedure usually works well for us.

Where my questions comes in is if I go back into the original operation
to edit any parameters, this statement "pops" on the screen
"All instances of this operation will be edited"
and when I regenerate the operation it looks as if all the instanced operations also get regenerated.
But after a closer look I have discovered that instanced operations HAVE NOT changed ,
that in fact they still have the original toolpath.

To get around this problem I delete the instanced operations then re-translate the operations.

Can someone please tell me how come the instanced operations are not updating when UG tells me that
"All the instanced operations WILL be updated."

Thanks ,
Brian

I'm not in front of a seat of NX, but last I knew Transforms were not associative or parametric....it's basically how we used to Move objects in UG/NX (which for the most part has been replaced by the Move command, except for what is still available on the Transform dialog).

Use Instance Geometry or Feature Array (maybe called Instance Feature)....however, not having a machining background, I cannot say that toolpaths are valid entities for this type of workflow....but there might be a command that is unique to the CAM module that will allow for toolpaths to be arrayed/instanced.

Some people are like slinkies....they don't really have a purpose, but they still bring a smile to your face when you push them down the stairs.

Call GTAC. Sound like a bug. Under normal circumstances if you translate an Instance it should work as you did.
