Introduction to Drafting Tools

Objectives:

  • Properly use and maintain basic drafting tools and equipment
  • Understand and use the alphabet of lines
  • be able to read and measure with a variety of drafting scales
  • Develop production quality linework that can be reproduced
  • Develop lettering skills

What & Why?

Hand drafting has proven to be one of the great tools for learning concepts important to the drafting process. Students learn and retain concepts better when they have to physically manipulate the content. Even though most technical working drawings are now created using CAD; the individual who has developed a basic understanding of drafting presentation principles through hand drafting will ultimately be a more knowledgable and skilled drafter.
