Oh, no's! I think it could have something to do with the winding rules. Which would be a bit hard to fix, since I don't know how to ”see” from the plugin. I'll have a look.

I can't really figure this out yet. The only thing I can find is a workaround:

  1. Duplicate the line.
  2. Intersect the line and its copy.
  3. Separate the intersection and the oval.

Not sure if this is what you're looking for, but layer.windingRule() will return either 0 for NSNonZeroWindingRule or 1 for NSEvenOddWindingRule

Here is a slightly better workaround: If the split fails, undo and redo it with the start and end points of the line reversed.

Hi guys. My opinion is that there is no need to fix the "Separate SHAPES" plugin. Actually, it is not a bug! A line is not really a shape! In Adobe Illustrator, you could not achieve this (I tested it in the last version), and it is normal.

If you really want to achieve this, you can use a 1px height rectangle instead of the line… and it works!

@PEZ Congratulations for this great plugin.
