Technical Drawing 101 - A Multidisciplinary Guide to Drafting Theory and Practice - with Video Instruction

Oct 28, 2026

Technical Drawing 101 introduces what technical drawings are and how they support the fabrication of electronic and mechanical products and the construction of houses, buildings, roads, bridges, and water and wastewater systems. It explains key terminology and the overall design workflow from defining design criteria, ideation, and client review to producing detailed design inputs for drafters. It also describes the origins of technical drawing and the modern role of CAD tools such as AutoCAD and Revit.

In fact, technical graphics are produced before almost all products are manufactured—from the electronic devices inside your cell phone to the handle of your toothbrush.

Through the ages, architects and designers, including Leonardo Da Vinci, created technical drawings. However, a French mathematician, Gaspard Monge, is considered by many to be the founder of modern technical drawing. Monge’s thoughts on the subject, Géométrie Descriptive (Descriptive Geometry), published around 1799, became the basis for the first university courses. In 1821, the first English-language text on technical drawing Treatise on Descriptive Geometry, was published by Claudius Crozet, a professor at the U.S. Military Academy. Other terms often used to describe the creation of technical drawings are drafting, engineering graphics, engineering drawings, and computer-aided design (CAD). 1.2 THE ROLE OF TECHNICAL DRAWING IN THE DESIGN PROCESS To appreciate technical drawing’s role in the design process, you must first understand some basics about the design process itself. For most projects, the first phase of a design project is to define clearly the design criteria that the finished design must meet to be considered a success. Many designers refer to this phase in the design process as problem identification. For example, before designing a house, an architectural designer needs to know the size and style of home the client wants, the number of bedrooms and baths, and the approximate budget for the project. The designer also needs information about the site where the house will be built. Is it hilly or flat? Are there trees, and if so, where are they located? What is the orientation of the site relative to the rising and setting of the sun? These concerns represent just a few of many design parameters that the designer needs to define before beginning the design process. Once the design problem is clearly defined, the designer begins preparing preliminary designs that can meet the parameters defined during the problem identification phase. During this step, multiple solutions to the design problem ma

FAQs

What are technical drawings used for?

Technical drawings are graphics and documentation (including notes and specifications) used by manufacturers and construction professionals to build and fabricate products and infrastructure. They guide work from initial concept through production-ready documentation.

How does technical drawing relate to the design process?

The design process starts by defining design criteria, then generating multiple solution concepts, and reviewing preliminary designs with clients. After the client approves, designers prepare detailed design inputs that drafters transform into technical drawings.

What CAD tools are mentioned as commonly used for technical drawings?

The text lists popular CAD programs including AutoCAD, Revit, Autodesk Inventor, SOLIDWORKS, and Creo. These tools help drafters produce drawings much more quickly than traditional drafting techniques.
