AutoCAD 2-D Basics

John Andrew, P.E.

Course Outline

This 6 PDH course summarizes the AutoCAD tools and methods for making typical multi-view two dimensional: manufacturing plant plans, elevations, mechanical and structural engineering drawings, flow charts, process, instrumentation and electrical power and control diagrams.

The techniques described here include all versions of AutoCAD released during the past 10 years, including releases 14 to 2007. AutoCAD LT is 2-dimensional and AutoCAD Professional is 2 & 3 dimensional.

The methods described are applicable to the: Mechanical, Structural, Industrial, Chemical, Electrical, and Civil engineering disciplines.

AutoCAD software is not required to study these notes and answer questions in the quiz.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Intended Audience

The information will be especially useful to: students, entrepreneurs, engineers, architects, and innovators who want to be able to make Computer Added Drawings (CAD).

Benefit to Attendees

Attendee of this course will know how to make scale dimensioned engineering and architectural drawings and diagrams with all releases of AutoCAD from 14 to 2007.

Course Introduction

The AutoCAD release 2007 manual has over 1000 pages. This lesson has only 60 pages but the most used drawing methods are described, enabling the reader to make all types of two dimensional engineering diagrams and drawings.
