Intersecting Holes
Origami does not support more than one hole in the same place. So if you see this error you probably have two holes that overlap in your die drawing:

The other possibility is that you have one hole nested inside another:

You need to make sure there are no hole intersections in your die-drawing.
What to do?
- Find the intersecting holes.
- Combine overlapping holes and delete nested holes.
- Make sure the error disappears.
Want More Hints?
- Almost Vertical/Horizontal — crease line is probably misaligned;
- Broken Shape — shape is broken apart when folding;
- Path Is Not Closed — the dieline needs a solid, continuous outline path;
- Crease Line In Main Outline — the main outline must be made of cuts;
- Intersecting Curved Cuts — it might not be easy;
- Empty Layout — why there is no dieline visible?
- Hanging Element — what if a path goes nowhere?
- Impossible Crease Line — a crease that shouldn't be;
- Inconsistent Crease Lines — similar crease lines must have same angles;
- Invalid Crease — crease lines have limitations;
- Overlapping Lines — cut and crease lines must not overlap, as well;
- Separate Element — the dieline should come in one piece;
- The Points Are Too Close — avoid crowded spaces;
- Z-Fighting — what to do with overlapping polygons.
There's more from the older folding engines:
- Intersecting Holes — holes must not overlap;
- Impossible Shape — some shapes simply don’t exist;
- Outside Hole — all holes must be inside the outline path;
- Misaligned Elements — ends must meet, perfectly;
- Elements Are Too Small — keep dieline paths simple;
- Triangulation Failed — Origami fails to make a 3D mesh of a dieline.
