Chapter 03 - Task 1 - 🟩 Create and Connect a List of Number
Goal: Understand list creation and numeric data flow.
💡 Task:
Create a list of numbers from 1 to 10, by 2 ways and verify how Dynamo groups them as one data stream.
✅ Expected Output:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Chapter 03 - Task 2 - 🟩 Create a List of Points
Goal: Generate geometry from list data.
💡 Task:
Use a list of X-coordinates (0 → 4) and constant Y and Z = 0 to create 5 points along the X-axis.
✅ Expected Output:
Five points in a straight line along X.

Chapter 03 - Task 3 - 🟩 Access Specific Items by Index
Goal: Extract individual items from a list.
💡 Task:
From the point list in Task 2, get the point at index 3 and highlight it in the 3D preview.
✅ Expected Output:
Point at X = 3 selected.

Chapter 03 - Task 4 - 🟩 Count List Items
Goal: Verify list length using a node.
💡 Task:
Create a list of any 7 numbers and find how many items it contains.
✅ Expected Output:
7

Chapter 03 - Task 5 - 🟨 Combine Two ListS
Goal: Pair related data between lists.
💡 Task:
Create one list of room names ["Living", "Kitchen", "Bath"] and another of areas [25, 15, 10]; combine them into single strings like “Living = 25”.
✅ Expected Output:
["Living = 25", "Kitchen = 15", "Bath = 10"]

Chapter 03 - Task 6 - 🟩 Reverse a List
Goal: Change item order.
💡 Task:
Reverse the sequence of the list [1, 2, 3, 4, 5].
✅ Expected Output:
[5, 4, 3, 2, 1]
Tags: #lists #order #manipulation
Chapter 03 - Task 7 - 🟨 Flatten Nested Lists
Goal: Simplify multi-level list structures.
💡 Task:
Start with [[1, 2, 3], [4, 5, 6]] and flatten it into a single list.
✅ Expected Output:
[1, 2, 3, 4, 5, 6]
Tags: #lists #nesting #flatten #levels
Chapter 03 - Task 8 - 🟨 Map an Operation to a List
Goal: Apply the same function to every item in a list.
💡 Task:
Given [2, 4, 6, 8], double each number to produce a new list.
✅ Expected Output:
[4, 8, 12, 16]
Tags: #lists #map #iteration #function
Chapter 03 - Task 9 - 🟨 Experiment with Lacing
Goal: Explore how Dynamo handles lists of different lengths.
💡 Task:
Create two lists of lengths 3 and 5 and connect them through a math operation; observe results for Shortest, Longest, and Cross-Product lacing.
✅ Expected Output:
Shortest = 3 results, Longest = 5, Cross-Product = 15.

Chapter 03 - Task 10 - 🟨 Create Points from Two Lists
Goal: Combine parallel lists into geometry.
💡 Task:
Use X-list (0 → 4) and Y-list (0 → 4) to create points at matching coordinates (X,Y).
✅ Expected Output:
Points (0,0), (1,1), (2,2), (3,3), (4,4).

Chapter 03 - Task 11 - 🟨 Extract Revit Element Parameter Li
Goal: Access structured data from the model.
💡 Task:
Collect all walls in Revit and extract two parameters — Length and Area — as separate lists.
✅ Expected Output:
Equal-length lists of numeric values for each parameter.
Tags: #revit #parameters #lists #elements
Chapter 03 - Task 12 - 🟨 Filter Revit Elements by Parameter
Goal: Apply list filtering logic to model data.
💡 Task:
Using the wall length list from Task 11, filter only walls longer than 5 meters.
✅ Expected Output:
List of wall elements meeting the condition.
Tags: #revit #filter #lists #boolean
Chapter 03 - Task 13 - 🟥 Merge Multiple Parameter Lists int
Goal: Combine complex Revit data into a readable format.
💡 Task:
For all walls, collect Length, Area, and Type Name parameters, then merge them into a single structured list or table for export.
✅ Expected Output:
[["Wall1", 5200, 14.5], ["Wall2", 3600, 9.7], ...]

Chapter 03 - Task 14 - 🟥 Find Maximum and Minimum Values in
Goal: Analyze data inside lists.
💡 Task:
From a list of wall lengths, find the maximum and minimum values and highlight the corresponding elements in the Revit model.
✅ Expected Output:
One “Longest Wall” and one “Shortest Wall” highlighted.
Tags: #revit #analysis #lists #minmax
Chapter 03 - Task 15 - 🟥 Filter Elements by Two Parameters
Goal: Combine multiple filters to refine selection.
💡 Task:
Collect all walls, then filter those whose Area > 15 m² and Length > 5 m.
✅ Expected Output:
Only walls satisfying both conditions remain.
