Topics.
1. What is Lacing and thier Types.
2. Automatic/Shortest_Lacing
3. Longest
4. Cross Products
5. Learning Sources
6. Conclusion
What is Lacing?
? Lacing is a feature in Dynamo that allows you to control how lists of different
lengths interact with each other.
? The Lacing mode dictates how one input connects to another input for a given
node.
As mentioned below there are 4 Type of Lacing mode which you can find in
Dynamo and you can easily find which method is being set currently
Automatic/Shortest
? When you place a node, you will notice that it is set to Automatic.
? Both modes will almost always result in the same output and therefore are
commonly considered to be the same mode.
? The difference is in the way Shortest and Automatic are written out in the code
under the hood of Dynamo.
? Shortest refers to the “Shortest List” algorithm. This is the simplest way to
connect inputs.
? When Lacing is set to this mode, inputs are connected one-on-one until one of
the lists runs out.
Auto/Shortest
Longest
? Dynamo will simply reuse the last element from the shortest list for the
remaining elements in the longer list.
? when the Lacing was set to Automatic and Shortest now have lines drawn to
the last point from the shortest list and there are no points from either list that
remain unconnected to another point.
Longest
Cross Product
? Each element from the first list will be connected to each element of the second list.
? we now see that every point in one list has a line drawn to it from every point in the
other list.
? Notice that the lines are only drawn from one point in the first list to another point in
the second list and that no points in the same list are connected.
Cross Product

Conclusion.
? Changing the Lacing for a given node can drastically change the output of
that node.
? Lacing affects the connection between lists, grants you the ability to
control how multiple sets of data that are different in length are handled
for a given node.
? It allowing you to better manage the data in your script.
? While data matching isn’t the entire iceberg that is data management, it
is a very crucial part and understanding how to control it is a huge step
towards mastering data management in Dynamo.
