In a few locations, python objects are used without checking if they
exist and are non-null, which throws missing attribute exceptions. The
fix is to simply check first.
When adding tool controllers from the job dialog, it will now
try to match the toolbit file with the currently selected library
and add use the toolnumber from there. If no match is found,
it will autoincrement from the existing tool controllers
in the job
Fix bug identified by MLampert. This fix addresses extensions for circular faces that have non-extended holes in the face.
.
Unlike polygon extensions that only need one wire to define the extension shape, some circular extensions require two wires (a face would be better) to define the extension area.
.
Restructure to accommodate future `Extensions` improvements
These changes allow for better identification of horizontally planar faces, and also improve handling of circular arc faces that failed previously for use with ball-end bits.
This fix also improves slot creation based on selection of two arc edges for ball-end slot creation.
Fix the bug hindering update of the Default Length spin box in the Extensions tab after editing and change of focus.
With the fix, the spin box updates after change of focus, as do other spin boxes in the Path workbench.
Used method found in PathDrillingGui module.
Depths were being calculated incorrectly due to MIC distance getting
divided by scaling factor rather than multiplied by it.
The scaling factor is the inverse of the tan of half the cutting tool
angle, so for a 30 degree bit (say), the scaling factor would be
1 / tan(30/2), or 3.7320.
When given an MIC (which is a radius) of 3.175 (say), and cutting to the
same width with a 30 degree bit, the depth should be 3.175 * 3.7320
(11..849), not 3.175 / 3.7320 (0.8509) as it is currently.
Identified by MLampert. If multiple faces are selected at varying Z-heights, the `combineConnectedShapes()` method fails to connect them due to offset Z-heights. This fix places all input faces for that method into the same working plane.
