CAD vs Conventional Drawing: Understanding the Differences
Here's a blog post that explains in detail the differences between CAD and conventional drawing.
Computer-Aided Design (CAD) and conventional drawing are two methods of creating technical drawings that are used by architects, engineers, and designers. Each method has its strengths and weaknesses, and the choice between the two will depend on the specific needs of the project. In this blog post, we will explore the differences between CAD and conventional drawing in detail.
CAD: The Digital Approach to Technical Drawing
CAD is a digital method of creating technical drawings that has become increasingly popular over the years. CAD software is a powerful tool that allows designers to create detailed and precise technical drawings with ease. Some of the key features of CAD include:

Computer Software:
CAD software is designed to run on a computer. This software can be used to create 2D and 3D drawings with the help of a mouse or digitizing tablet.
Precision and Accuracy:
One of the biggest advantages of CAD is that it offers high levels of precision and accuracy. CAD drawings are created using mathematical algorithms, which ensure that each line, angle, and dimension is precise.
Quick Modifications:
Another benefit of CAD is that it allows for quick and easy modifications to be made to the drawing. If changes need to be made, designers can simply make the necessary adjustments in the software.
Collaboration and Sharing:
CAD drawings can be easily shared with other team members or collaborators. These drawings can be emailed or uploaded to a cloud service, which makes it easy for others to access them.
Replication and Modification:
CAD drawings can be replicated and modified with ease. This means that designers can use a single drawing to create multiple designs, or modify an existing design to create a new one.
Conventional Drawing: The Manual Approach to Technical Drawing
Conventional drawing is the traditional method of creating technical drawings that has been used for centuries. This method involves the use of tools such as pencils, rulers, protractors, and drafting tables. Some of the key features of conventional drawing include:
Manual Tools:
Conventional drawing requires the use of manual tools, such as pencils, rulers, and protractors. These tools must be used to create each line, angle, and dimension on the drawing.
Creativity and Expression:
One of the benefits of conventional drawing is that it allows for greater creativity and expression in the drawing process. Designers can use different techniques, shading, and textures to create unique and personalized drawings.
Time and Effort:
Conventional drawing can be more time-consuming and labor-intensive than CAD. Creating a detailed and precise technical drawing can take a significant amount of time and effort.
Revision and Correction: Conventional drawing is often less precise than CAD, which means that it may require more revision and correction. If a mistake is made, the drawing may need to be redone from scratch.
Replicability and Sharing: Conventional drawings are limited in terms of replicability and sharing. They must be physically transported or scanned in order to be shared with others.

When it comes to choosing between CAD and conventional drawing, there are several factors to consider. These include the complexity of the project, the time available, the level of precision required, and the resources available. Here are some factors to consider when choosing between CAD and conventional drawing:
Complexity of the Project:
If the project is complex, with multiple dimensions, angles, and sections, CAD may be the best choice. CAD allows for the creation of highly detailed and precise technical drawings that may be difficult to replicate with conventional drawing.
Time Available:
If time is a critical factor, CAD may be the best choice. CAD allows for quick modifications and can save significant amounts
