Technical drawing and schematic are two terms that are commonly used in the world of engineering and design. However, they are not interchangeable.. In this blog post, we will discuss in more detail the differences between technical drawing and schematic, their uses, and which one is suitable for your project.
What Is a Technical Drawing?
A technical drawing is a detailed graphic rendition of how something functions or how it is built. Technical drawings are made at a precise scale and include elements that make them unambiguous, meaning that their elements can be interpreted only in one way.
Technical drawings are essential to processes such as manufacturing, where an easy-to-understand visual representation of a product or component is necessary.
These drawings are created using a variety of tools, including traditional pencil and paper and computer-aided design (CAD) software.
What Is a Schematic?
Schematics (also known as schematic diagrams) are drawings used to represent a variety of technical systems in a simplified way.
In a schematic diagram, components are represented by symbols, and lines connect them, indicating their relationship and the flow of current or other interactions between the components.
Schematic diagrams are created using some of the same tools used for technical drawing, including software like AutoCAD.
Summarizing, you could say that technical drawings are used for objects, while schematics are used for systems. Therefore, it’s essential to know when to use each in order to convey the necessary information for your project.
