CAD Problem Bank

The following CAD problems were taken from the Introduction to CAD course problem set. The AutoCAD Problem Bank problems consist of 27 drawing problems designed for use with a beginning AutoCAD class. The problems are created to be self-contained assignments ready to be used without modification in a CAD class. Each problem includes information on the commands introduced in the assignment, the level of difficulty, instructions, and expected duration. In addition, each problem includes variations which enable the instructor to tailor the assignment to the individual level of the student or class and essentially allows a nearly limitless supply of drawing assignments. The drawings presented in the problem bank were all created according to the latest industrial standards of multi-view orthographic projection, dimensioning, and tolerancing.

The Drawing Template Files are listed at the bottom of the page.

Command Matrix

Beginner Level Drawings
The focus of the beginner level drawings is to expose the student to the basic drawing and modifying (editing) commands. The students will be introduced to the process and syntax that AutoCAD enforces for creating two-dimensional drawings. The drawings at this level are entirely composed of single-view orthographic views.
Beginner Level Matrix

Intermediate Level Drawings
The focus of the intermediate level drawings is the construction of progressively harder and more realistic geometry. Layers and multiple orthographic views will be introduced. The rate of introduction of new commands will decrease to only one or two new commands per drawing as the student will encounter more difficult and time-consuming drawings.
Intermediate Level Matrix

Advanced Level Drawings
The drawings at the advanced level all focus on the construction of real-world drawings from the mechanical industry. All drawings involve multiple orthographic views, layer usage and dimensioning. The drawings denoted with a b (i.e. 3.1b, 3.3b, 3.4b) include size and/or geometric tolerancing (GD&T), as well. All dimensioning is per the ASME Y14.5M Dimensioning and Tolerancing standard.
Advanced Level Matrix


Suggested Sequence of Assignments

The instructor can determine the ideal sequence of problems for their class. The problems were organized according to an increasing level of difficulty. Each high number problem is meant to reinforce previous concepts and commands so that learning is progressive, gradual, and cumulative. The original intent was as an almost sequential set of problems. However, they may be used in any desired order or selected on an as-needed basis to fill any available time slot.
