Drafting & Design 20

Prerequisite: Drafting & Design 10

This class explores: Computers

2D & 3D Drafting and Design

Engineering/Mathematical Problem Solving

Architecture

House/Floor Plans

Students continue developing their Mechanical CAD skills. More complex items and objects will be drawn. Students also draft nuts and bolts, and assembly drawings that show how a number of parts form one object.

Architectural design is introduced. Students will design and draft a cabin, complete with a floor plan and elevation drawings. Standard building component sizes and code standards will be introduced and followed.

2D & 3D drawings begin to become more complex. See the files below for examples.

^ Mechanical CAD - Sections: This object shows an example of a removed section drawing. Picking up from the Section unit started in Drafting 10, removed sections allow for multiple cuts and views and even further clarity. Offset and revolved sections are also explored.

^ Mechanical CAD - Assembly Drawings: these are just what they sound like: drawings that show how parts are assembled to form an object. 3 different types of assembly drawings are studied: exploded, outline, and orthographic.

Introduction to Architectural CAD: students will design their own cabin floor plan and elevations. Sizes of building materials, as well as building codes, must be communicated and followed. Practical and efficient design is also studied.

*Note: to enhance clarity, the floor plan and elevation above are not shown at the same scale.

^ Intermediate 3D CAD: building off of skills learning in 3D Drafting 10, students learn to draw more complicated objects like spheres and Stanley Cups. The cabin designed will also be converted into 3D format.

Much like in Drafting 10, Drafting 20 students are also encouraged to continue Free Design drawings:
