Drilling Change at Point - How to Undo?

[Bill H]

In a drilling toolpath, I've used the 'Change at Point' functionality to alter the parameters at several points.  How can I undo these changes and return to the default values? MC2019

Unlock it and Regen?

[Bill H]

I'll be more specific.  Let's say the toolpath has ten points and I've set the retract value to 0.1" absolute.  To avoid a clamp, I use Change at Point and put in a jump height of 2.0" at point #4.  Whoops - I meant to use the jump height at point #6.  How do I remove the change that I've put in at point #4?  If I put in a value of 0 for the jump height, this overrides the retract value.  I'm looking for a 'do over' - a way to get rid of my changes and return all parameters to their original values.

I only have 2020 installed here at home so I can't test it in 2019 but the best bet might be to delete the point and re-select it..then move to the point you want to edit

JParis - That's the only method that I've found that works reliably.  I was hoping there was a simple 'undo' or 'restore defaults' option.

You can when reset the value....ie, you have a 2" Retract as your Clearance and set a 6" Jump Height....go back in to edit the 6" back to 2"

JParis - The problem with doing it this way is that if I now change the 2" Retract to 3", the Jump height stays at 2".  In other words, for the point where the 'Change at Point' was applied, it doesn't seem there's a way to undo the change and get the changed parameter to follow the Linking Parameters values - other than your suggestion of re-selecting the point.

Can you change your points in a way that would start on one side of the clamp and finish on the other side?

Unfortunately, in 2020 or before, you cannot "undo" a change at point.

Change at point was tied into the editing the drill points' properties at a really low level for the past 30 years or so and we didn't have time to wade into that area until recently. As soon as you activate it on a point, it's manually overriding all of the set parameters.  They're not looking at the linking page at all. Your only option is either to delete the point and re-select, or to just set it to the value that you want it to be (note that it will not be updated by the linking page if you change it in the future).

In 2021, we've started to try to clean up some of that, and as a consequence you can now clear your changes:
