Partial Overlap Multi-Paper
Partial Overlap Multi-Paper problems involve two or more separate papers placed with partial overlap, then punched together. Unlike folding, the papers are not physically connected. Each paper receives its own holes based on where the punch penetrated it. These problems test your ability to handle multiple independent objects and relative positioning.

Introduction to Partial Overlap Multi-Paper
Partial Overlap Multi-Paper problems involve two or more separate papers placed with partial overlap, then punched together. Unlike folding, the papers are not physically connected. Each paper receives its own holes based on where the punch penetrated it. These problems test your ability to handle multiple independent objects and relative positioning.
Prerequisites
How to Solve Partial Overlap Multi-Paper Problems
Step 1: Identify the positions and orientations of each paper
Step 2: Identify the overlap region(s) where multiple papers are stacked
Step 3: Note the punch position in the global coordinate system
Step 4: For each paper, determine if the punch falls within its boundaries
Step 5: If the punch falls on a paper, that paper gets a hole at that relative position
Step 6: Papers may have different coordinate systems (if shifted/rotated)
Step 7: The final result is the set of holes on each individual paper
Example Problem
Example: Two identical square papers placed with 50% overlap (one shifted right by half its width). A hole is punched in the overlapping region. What happens? Solution: Step 1: Paper 1: positions 0-100; Paper 2: positions 50-150 Step 2: Overlap region: x = 50-100 Step 3: Punch at x=75, y=50 (global coordinates) Step 4: Paper 1: punch at (75,50) relative to its origin Step 5: Paper 2: punch at (25,50) relative to its origin (since 75-50=25) Step 6: Each paper gets one hole at its respective relative position Step 7: The two holes are at different positions on each paper Answer: Two holes total - one on each paper, both in the region that was overlapping
Pro Tips & Tricks
- Papers are independent - no reflection or symmetry applies
- Each paper gets at most one hole per punch (not multiplied by layers)
- The punch position must be converted to each paper's coordinate system
- Papers may be shifted, rotated, or scaled relative to each other
- The number of holes = number of papers that cover the punch point
- Overlap region is where multiple papers have holes from the same punch
