In this video, I explain why data matching is one of the most important ideas in Grasshopper.
The example is simple: two curves, two sets of points, and lines between them.
But when the point counts do not match, the result changes.
The main idea is simple:
- Matching lists creates clean connections
- Different point counts create unexpected results
- Grasshopper follows the data structure you give it
- Better control starts with checking inputs and outputs
