OUR message is to build a better world not destroy one 🇵🇸!
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 - 🟩 Units and Geometry Measurement
Goal: Confirm correct understanding of model units.
💡 Task:
Create a straight line one meter long, measure its length, and convert the result to millimeters and feet.
✅ Expected Output:
1 m → 1000 mm → 3.28084 ft.

Chapter 02 - Task 5 - 🟩 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 6 - 🟩 Compare Two Node Search Methods
Goal: Measure efficiency in finding nodes.
💡 Task:
Create the same graph twice — once using the left Library panel, and once by typing node names in Search — and compare which is faster for you.
✅ Expected Output:
Time difference recorded.

Chapter 02 - Task 7 - 🟨 Backup and Recovery
Goal: Locate and restore Dynamo backup files.
💡 Task:
Force-save a small graph several times, locate its backup folder, delete the main .dyn file temporarily, and recover it from the backup copy.
✅ Expected Output:
Recovered graph opens and runs successfully.
Tags: #interface #backup #recovery #filesafety
Chapter 02 - Task 8 - 🟥 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.
