Drafting & Design 10

Prerequisite: Grade 9

This class explores: Computers

2D & 3D Drafting and Design

Engineering/Mathematical Problem Solving

Architecture*

Any student interested in computers as well as drawing and designing should strongly consider Drafting 10. Students are introduced to basic CAD (Computer-Aided Design) skills. We use AutoCAD 2021 for software. Students start out with assignments to teach them the basic skills of AutoCAD, which include drawing lines, shapes, and layers. Example assignments include drawing the front side of a house and car (shown below).

These skills will eventually lead students to draw 2D drawings, and then convert them into a 3D format. The introductory CAD assignments are excellent problem-solving exercises and use a great deal of mathematics. This type of Drafting is often referred to as "Mechanical Drafting", where different parts of machines and other objects are drawn to scale.

Students are also challenged to come up with a Free Design Drawing by the end of the semester. Some examples of past students' Free Design Drawings can be found below and under the 'Student Work' tab on the left.

*Note: If you are interested Architectural Drafting (house plans, blueprints, 3D Models), these areas are explored in Drafting 20 and 30. Taking Drafting 10 first is highly recommended to build a strong skillset on CAD.

^ The car above is an example assignment used to teach students basic CAD skills.

^ Introduction to Mechanical CAD: All three drawings above represent the same object. The multi-view (orthographic) drawing is created to show "straight-on" perspectives and to easily communicate dimensions. The isometric provides the viewer with an overall idea of what the object looks like, but is drawn with distortion. Finally, the 3D version (red) allows the drafter or viewer to orbit around the entire object and view from an viewpoint possible. The objects get more complex and challenging as the semester goes on (learning to how draw curves, countersunk and counter-bored holes, and tangents are a few examples).

^ Mechanical CAD - Sections: On the left is an orthographic section, the right shows an isometric section. Both drawings represent the same object. Sections are used when internal detail is to be shown or to provide better clarity of objects or parts.
