I think it's only been an issue since I updated. Now when I make a drill operation the heights are way off. If the top and bottom are "hole top" and "hole bottom" it's always showing that the operation starts excessively high up and then also much too deep. On a blind hole even the operation will show that it goes well below the part. I can use a manual selection and select the top and the bottom of the hole and the toolpaths will be correct but it's a slight annoyance.
Do you have a part that you could share with us to show as an example? I'm wondering if there was a method of setting up a job or defining a feature that isn't allowed anymore, or a loophole that was closed perhaps. It's happened before; A method of doing something shouldn't work, but does. People learn that method. One day it gets fixed so it no longer works and their are more than a few people who have issues.
I'd definitely qualify this as a bug.
Looks like the drilling operation is related to the Origin planes; maybe the drilling operation is ending at the equal depth of the drilled holes from the origin plane? Hard to tell indeed:
Had to create an angled plane and a line at the origin because the origin planes seem to disappear when I try and align them with the Top or Bottom views (where they would be in line with the part and toolpath).

@cmelojr@Anonymous@Steinwerks@LibertyMachineI logged this issue as ticket #CAM-4619. I will take a look at it ASAP. I will keep you updated about progress. Thanks for letting us know about it.

Alternatively you could try to align your model with origin. I cannot speak with 100% confidence without seeing your model, but model shifted relatively to the origin is causing problem in the example provided by @Anonymous Hopefully this is feasible workaround for your needs while we are working on the better solution
@cmelojr@Steinwerks@Anonymous@LibertyMachine
I would like to let you know that bug resulting in wrong drill heights was fixed and the fix will be released soon.
Thank you for your patience.

Awesome, it will be a huge help to everyone that deals with a lot of imported models and assemblies like me!
This a major set back for me. Trying to drill holes is now a crap shoot to get right. Sometimes if I make the bottom of the hole relative to the top or stock bottom it works. But if it's a blind hole then it doesn't seem to matter what I specify. I also see in the tool list that the overall height of drills will jump to 50" inches after I select them.
Please post a workaround. Also, there have been at least two updates since this bug was logged and it's not been fixed in the latest I received today.
I cannot complete a critical project because of it.
Thanks

You can always use selection for heights. So for a blind hole you could select the bottom and top circles that make the hole you are trying to drill. I find that using the "hole top" or "hole Bottom" throws the operation completely out of whack. Remember you can still use "drill tip though bottom" to go the extra distance to make it to the very bottom of a blind hole.
It's a definite pain in the **** but that's how i've been making it work.
@cmelojr @Kenatic @Steinwerks@LibertyMachine@Anonymous I would like to let you know that fix for drill heights was included in the latest update. Things should work as expected in ver 2.0.2377. Please let me know if it isn't so. Thank you for your patience.
It appears to be working proper on my models. Thank you!
In the drill operation the default top heigh is (now) set to the hole top. In other operations, it is more logically set to stock top. Of course you can manually make the right choice but this is quite dangerous.
More over, the top and bottom heights do not show up on screen and this lets you think they are up with the 2 others...
Found this problem out after hammering into my piece...
Did they break it.. again... 😉 I'm not doing a lot of CAM these days, but I did happen to do a drilling operation with the workpiece height quite a bit off from the hole height. this would not have been good if I took an update...
As far as I recall, it's always been "Hole Top" and "Hole Bottom".
If you prefer you can change the default settings in that field. Right click on the toolpath and select "compare and edit", type in "Top Height" into the dialog box, set to the setting you prefer and right click > set as default
May be then it has not always been the right thing.
When you drill a hole it may be safer to specify from stock top on a regular basis, no ?
What about the fact that the top and bottom planes do not show up on screen (cf the .png attached.)
