Core and Optional Modules

Module 9: Auxiliary Views and Revolutions (Core)

Suggested Time: 10-20 hours	Level: Intermediate
Prerequisite: Module 1 or 2 and 4

Foundational Objectives

To be able to describe shape in a multi-view drawing.
To maintain a high standard of quality for drawings produced.

Common Essential Learnings Foundational Objectives

To use numeracy skills while producing auxiliary view drawings. (NUM)
To understand the difference between auxiliary views and revolutions. (CCT)

Note: other CELs may be emphasized here.

Learning Objectives Notes
9.1 To produce auxiliary view drawings. (TL, NUM) Students must first be able to identify the view that has the edge view of the inclined surface.

Start with objects that have only straight lines. Objects with arcs and curves can be drawn once the straight line objects have been mastered. (NUM)

Define auxiliary plane and truncated. (COM)
9.2 To add dimensioning to the drawings. (CCT) Adding dimensions to the drawing will help show the students that the auxiliary view gives the correct shape and size of the inclined surface.
9.3 To produce secondary auxiliary views. (Optional) Once primary auxiliary views have been mastered then secondary auxiliary views can be introduced. Keep the objects very simple. (TL)
9.4 To produce drawings using the revolution process. The difference between auxiliary views and revolutions should be discussed. Although the results are the same, the process of doing the two types of drawings should be emphasized.

Module 10: Advanced Dimensioning (Core)

Suggested Time: 5-10 hours	Level: Intermediate
Prerequisite: Module 6

Foundational Objectives

To be able to describe shape in a multi-view drawing.
To maintain a high standard of quality for drawings produced.
To become aware of the career opportunities that exist in the field of drafting.

Common Essential Learnings Foundational Objectives

To create drawings that demonstrate an understanding of the conventions of dimensioning and drawing symbols. (TL)
To become familiar with abbreviations and how to use them. (COM)
To use numeracy to meet the demands of dimensioning. (NUM)

Note: other CELs may be emphasized here.

Learning Objectives Notes
10.1 To place notes with and without leaders. (COM) An example of a note without a leader would be: Note all fillets and rounds 3mm.
10.2 To dimension counterbored and countersunk holes. (TL) It should be an expectation that when the drawing is completely dimensioned all size descriptions are clearly and easily read.

The dimensioning standards set out by the CSA should be followed.
10.3 To dimension angles and chamfers. When using CAD software, the computer can not always place the dimensions so they are most easily read; it is important that students understand that moving and manipulating dimensions is part of dimensioning. (CCT)
10.4 To use geometric tolerances. (NUM) Explain where tolerances are used and the reason for tolerances. If possible, have a machinist come in and speak to the class.
10.5 To dimension non-circular curves.
10.6 To use abbreviations correctly. (COM) Note: teachers should refer to a resources list.
10.7 To dimension assembly drawings.
10.8 To use finish symbols.
