Technical Drawing Instruments & Their Uses: A Beginner’s Guide

Technical drawings are an important part of drafting plans in a variety of industries. In construction, architecture and especially engineering, drafting precise plans, views, perspectives, and projections are crucial for success. While many industries depend highly on digital platforms, specifically CAD software, using traditional technical drawing instruments is still relevant.

Why Technical Drawing Matters

Technical drawing plays an important role in bringing a new project to life. Engineering drawing connects all aspects of a project, ensuring a success trajectory from engineering through to construction. Thus, a final blueprint or drawing requires clear language and a set plan for everyone on the team to understand.

In essence, a complete technical drawing brings the imagination of the team to life. With each draft, opportunities for improvement and expansion can be articulated. In addition, the financial estimate for the project can be reached using the details provided in the drawing.

Traditional Technical Drawing Tools

As a result, having the right instruments is important. More important? Knowing how to use them. Therefore, we put together this quick guide for you! The most important technical drawing instruments include the following.

  • Drawing pencils. These are the most basic instruments for professional technical drawers. The lead within each type of pencil is classified based on their hardness (H) or softness (B).
  • Drawing sheet. Drawing sheet is a white paper on which an engineer draws an object. It is available in various sizes and should be of good quality.
  • Drawing board. Drawing board is made of soft wood and is rectangular. An engineer uses it to support a drawing sheet. There are different types and sizes of drawing boards with IS classifications.
  • Compass. An engineer uses a compass to draw circles and arcs. It has two moveable arms. The engineer places one arm at the center of the circle while moving the other to draw the arc.
  • Set squares. These tools are two plastic triangular templates. An engineer uses them to make precise angles and parallel or perpendicular lines.
  • Protractor. An engineer uses a protractor to measure the angles of lines in the drawing. It is transparent, plastic, and is shaped in a semi-circle.
  • French curves.  These irregularly shaped tools draw curves to find the section of the curve that matches the shape of the figure.
  • Circle templates. Templates are plastic or wooden boards shaped like a circle. Using this template ensures a perfect circle every time.
  • T square. An engineer uses this tool to draw horizontal and vertical lines. It made of wood or plastic and in T shape. The vertical part of T is called a blade and the horizontal part of T is called a head.

After You’ve Finished Your Drawing

Once your technical drawing is finalized, the project is complete and you can revel in your success, consider how you store the drawing that made it all happen. As a result, you should keep a blueprint from a successful project and reference it when necessary or for inspiration in future projects. Luckily, there are several ways to store blueprints and drawings safely.
