The first discontinuity we need to fix is the path direction. This will make it easier for PrimeCut to determine how the segments should be joined.
At the bottom left corner of our part the paths are anticlockwise, while those for the rest of the part are clockwise.
1Use a 'crossing rectangle' (from right to left) to select the two segments that have an anti-clockwise direction:
This will select the bottom and lower left line segments
2Right-click to display the popup context menu.
3From the context menu Click the Reverse option. All of the segments on the part should now have the same clockwise direction.
PrimeCut will automatically set the direction as long as the path is closed. If the path is broken/open then the directions will be random.
