Chapter 02 - Task 1 - 🟩 Manual vs Automatic Run
💡 Goal: Compare Dynamo’s two execution modes.
● Task:
Build a small graph that multiplies a number by 2, then test how results update when using Manual mode versus Automatic mode.
● Expected Output:
Changing 5 → 10 should only update after pressing Run in Manual mode, and instantly in Automatic.

Chapter 02 - Task 2 - 🟩 Observe Node Preview
💡 Goal: Control visibility of geometry and keep the viewport clear.
● Task:
Create several point or line nodes, then disable the preview for all intermediate nodes and keep it only for the final geometry.
● Expected Output:
Only the final geometry remains visible in the Revit 3D view.

Chapter 02 - Task 3 - 🟩 Detect and Fix an Error
💡 Goal: Learn to read Dynamo warning messages.
● Task:
Intentionally connect mismatched data types (for example, connect a text input into a math node), note the warning, then correct the graph so it runs successfully.
● Expected Output:
Before = Yellow warning bubble
After = No warnings, correct numeric output.

Chapter 02 - Task 4 - 🟩 Organize Nodes and Groups
💡 Goal: Keep large graphs readable.
● Task:
Build a small graph with at least three stages (input → process → output) and organize them using Group colors and Notes.
● Expected Output:
Green = Inputs, Blue = Processing, Orange = Outputs.

Chapter 02 - Task 5 - 🟥 Inspect Node Lacing
💡 Goal: Understand Shortest, Longest, and Cross-Product lacing.
● Task:
Create two lists of different lengths and connect them through a geometry operation (Point.ByCoordinates); observe how changing the lacing mode affects the number of outputs.
● Expected Output:
Shortest = limited pairs, Longest = matches to longer list, Cross-Product = all combinations.
