First, when I fire it up, I get the dialog that has the angle set at 0.00000, and a selection is highlighted. However, when I hit extract, nothing happens. If I check “Copy” or “Border only”, the highlight disappears. In any case, nothing is extracted.
There is also the issue that the angle setting does not need 5 places after the decimal… A bit much, no?
Lastly, hitting the arrow on the “increment” - set to 10 by default - it goes by orders of magnitude - 100, 1000 etc… Not very useful either.
The dash version flashes the connected mesh faces when clicked, but they don’t stay highlighted.
In short, there is practically nothing about this command that works here currently.
