Broken path

On opening the attached file I get the following errors, though it looks OK in 3D view.

Enumeration index -1 is out of range, ignore it

On selecting "central-hole-Pocket" in Operations I get errors in report window.

Code: Select all

PathOpGui.INFO: Title: 'Pocket Shape'
Pocketing Select Mode
PathPocketShape.ERROR: getDirection(): tangent.cross(FreeCAD.Vector(0, 0, 1)).normalize()
PathPocketShape.ERROR: Cannot normalize null vector
PathPocketShape.ERROR: extendWire(): (ePts[0] - endPts[0]).Length
PathPocketShape.ERROR: list index out of range
PathPocketShape.ERROR: extendWire(): (ePts[0] - endPts[0]).Length
PathPocketShape.ERROR: list index out of range

The path looks to be as expected but I can't find out how to clean up the file to get rid of the errors. ( The gcode seems to make GRBL barf too, so I'm guessing I can't brush this under the rug. )

I previously had tried to add a third operation to face the surface but it did not work out so I deleted it. That is likely the source of the problems.

This is quite a complex profile sketch which I really don't want to start from scratch , again.

Is there a way to fix and clean up this file?

TIA.
