Summary

• Description:

  The PDF document comprises Grade 10 Building Construction Strand 2 Related Drawing Notes. The MS Word version (editable) is also available upon your request.

  It covers the following strands and sub-strands:

  • Strand 2.0: Related Drawing
    • Sub-strand 2.1: Isometric Drawing
      • Characteristics of Isometric Drawings: Understanding the three axes (Vertical, Left, Right), the 120-degree angle of separation, and the concept of "True Lengths" versus foreshortening.
      • Drawing a Shaped Block in Isometric Projection: Step-by-step application of the "Crate" or "Box" method to construct complex shapes from a master block.
      • Dimensioning Shaped Blocks: Rules for placing extension lines, dimension lines, and aligning text to parallel the isometric axes.
      • Importance of Isometric Projection: Its role in visualizing 3D details for plumbing, carpentry joints, and communicating ideas to clients who may not understand 2D plans.
    • Sub-strand 2.2: Computer Aided Drawing (CAD)
      • Types of CAD Software: Categories including General Drafting (AutoCAD, LibreCAD), Building Information Modeling (ArchiCAD, Revit), and Conceptual Modeling (SketchUp).
      • Setting Up a CAD Drawing Environment: Interface navigation, setting drawing units (Millimeters), configuring drawing limits, and using Grid and Snap functions.
      • Drawing Plane Shapes: Using Draw commands (Line, Polyline, Rectangle, Circle, Polygon) and Modify tools (Offset, Trim, Mirror, Copy).
      • Importance of CAD in Building Drawing: Advantages such as High Precision, Speed and Efficiency, Easy Storage/Sharing, and Standardization of drawings.
