0.20 regression? Drilling operation fails with a traceback

[knipknap]

I created a drilling operation with 0.19, and it works nicely:

When I open the same file in 0.20 (current daily), it still opens and displays fine, but upon clicking "recompute" on the drilling operation it creates a traceback:

This is a very strange file. You are trying to drill stepped holes with a tool that is too large for the smaller, deeper holes.

I can make the operation "work" with either the upper set or the lower set, but not both at the same time. By "work" I mean there is no crash. However there is also no path for the holes that are too small.

It is possible that there is some error that was not trapped in version 0.19, but the file needs to be sorted out before anything else.

True, I missed setting the correct tool diameter. However, after changing it to 3mm I see no change in the operation, the problem persists.

[GeneFC]

I still do not understand what you are trying to do. It is not physically possible to drill two different sizes within a single operation using a single tool.

Perhaps you want some sort of pocket instead of a drilled hole?

Does the problem occur in a new drill op or just the old one? Drilling got quite a bit of attention.

Here a new Drilling op works, while the old doesn't. The whole file may not be in good condition: It shows lost Surface and Slot ops on top level:

Hint to knipknap: You shouldn't create the clone yourself, but rather turn the clone inside of the Path job.

Hello Guys,

I'd like to drill holes on an alu profile, and I made the attached .FcStd in forward to achieve the goal.

Does anyone have any idea about what is the mistake, and how to make those holes well?

Thank You,

Setting StartDepth to 0.01 mm will get you going, whether this is a regression, not sure.

Thank You! Perfect!
