Error in tool_offsetview.py

The modified facing.py now works fine.
I think all tools, as you say, should work only in machine units, but I still have little practical experience, so maybe someone else will comment.
Another problem with the hole enlarger tool is that if you stop the program on the stop button while it is running, then when you start it again, the program does not start at x0 y0 but from where it stopped. Reloading the file doesn't help. Just like in the screenshot.
I modified the hole_enlarge.ui file so that it fits in the minimum size of qtdragon. If there is anything else to improve, please write.

Hi Chris

Have you tested the "hole enlarge" tool?
As it stands, I find it very dangerous to use it.

I think adding a G0 X0 Y0 Z clear command at the beginning would be a good improvement.
What do you think?

Oh I see it does have that in the beginning and the end.
I was assuming that was the dangerous part you are referring to.
Can you clear up my confusion?

I don't know enough about gcode to give any advice, but it's as if the X0 Y0 lines were skipped.In the first picture is what it is supposed to do, stop, start, and it makes holes bigger and bigger because it doesn't start at x0 y0
(pictures should be in reverse order)

I see the problem G91 is left over if you abort (if you don't have abort automatically reset G90.
It seems to work reliably if I add G90 in the beginning.
