Trimming a toolpath- want to remove a move i dont need

Tyler,

 

Say you rotate to some obscure Gview and window to trim the toolpath like WorkNC does. At that point in time, somewhere in the bowels of the software, there's a view or plane established (including the size of your window) to trim normal too, no? Why couldn't that be saved and used for re-trimming? I don't know the intricacies, I'm just asking.

 

Changing the stepover was just an example. Any parameter change that would cause the toolpath to become dirty could be substituted here.

 

yes something like that would work too (I would consider a plane to be a 'geometrical', but I'm just trying to backstep here).    There would have to be an instance of reference for the trim to happen, and that trim could be associative, absolutely - because it could just act as an operation occurring after the toolpath is created. 

 

In that case, isn't Mastercam's trim associative since if you change the toolpath and you use toolpath trim, the trim is regenerated when you regenerate the path?

 

 

I think we're talking about two different things - trimming, and editing. Trimming needs a reference, like a plane, a piece of geometry or some kind of entity to reference. Editing means selecting a series of points, or dictating some points you want to delete.  With editing, the reference could change with the stepover etc. so I don't see how that could be associative in any software without creating a potentially dangerous path
