Mechanical Drawing - Hand Tools


We start the year off by learning how to draw accurately by hand. This is an important skill for students to learn because in industry you sometimes need to modify designs on the fly without the aid of a computer.


Students also reinforce their skills in basic geometry and other mathematics as accurately recreate shapes. Students learn how to draw Isometric shapes and then split them into multi-view drawings.




Mechanical Drawing Basics

The activities that the students complete at the beginning of the year lay the foundation for the concepts and terminology that they will be using the entire year with either AutoCAD or drawings by hand.

These drawings re-introduce many concepts covered in math class such as perpendicular lines, parallel lines, supplementary angles, complementary angles, basic algebra, and others. Students learn the importance of accuracy while they use hand tools to create the complex shapes that are so easily created using computer software.

By the time students are done with the hand drawings, they understand the basic concepts needed to successfully utilize AutoCAD.


Introduction to AutoCAD 2012


During the remainder of the school year, the Technical Drawing Minor students will be using a piece of software called AutoCAD 2012. This software provides students with real world training skills because of the wide spread use of AutoCAD in industry today. Using this software to create drawings provides students with a glimpse of what it would be like to go into the engineering, manufacturing, architectural, and design field. The day to day projects that students will be completing challenge the students math, design and problem solving skills in order to accurately complete each challenge.



AutoCAD Basics

During the first 2-4 class periods, the students learn the very basic elements of AutoCAD. These elements include the user interface of AutoCAD, simple commands, mouse interface, and basic terminology. These elements are reinforced through a series of drawings that students have to complete.



AutoCAD 2d Drawings

As the students become more comfortable with the basic elements of AutoCAD, they  are introduced to new commands like "copy", "extend", "offset", "fillet", and many others. The difficulty of the drawings will also increase as the commands become more advanced.




AutoCAD Isometric Drawings

While the student were working with the hand tools, they were introduced to a type of 3d drawing called "Isometric Drawings". These drawings are being revisited while using AutoCAD to show how the skills that were learned earlier can be transferred into more complex drawings.

One of the most important lessons students learn while working with isometric drawings is the idea of perspective. One of the hardest skills for students to develop is the ability to perceive objects, without actually holding them, in 3 dimensions (height, width, length). These drawings that the students re-create help them to visualize how these objects should look in a real world environment and recognize when they are not proportionally accurate.

  AutoCAD Proportion and Scale Project  

This project challenges the students knowledge of AutoCAD, visual perspective, measuring skills, and many others as they attempt to take an object existing in real life and draw it to scale in AutoCAD. The students will need to go online and research these objects to get a basic idea of the size and scale of these objects. Once the students have found enough information they will be using what they have found to accurately draw their objects. Part of their drawing will be based on actual measurements, others will be based on comparison and proportions taken from images.
