Computer Versus Hand Drawing On Drafting Tables: Who Is Right, Who Is Wrong?

Whether in architecture, engineering, surveying or any other such field, high-quality, technical diagrams are essential for creating and communicating plans. For most of history, such plans have been drawn by hand, often with the help of drafting tables and similar equipment. In 1950, the first computer-aided design program was created. Since then, it has become ubiquitous as a technical design tool. So, is CAD better than hand drawing? The answer isn’t quite so simple.

What Is CAD?

Computer-aided design is a group of software products that help make designing easier. The first CAD program simply made drawing straight lines easier. Modern solutions allow users to create complex, highly precise models and diagrams entirely using a computer. In fact, CAD can be used for more than just drawing. It is also useful for planning materials and analyzing designs.

Although CAD is a very wide-ranging concept, when compared to hand drawing, the focus is on using computers to make technical diagrams. For this, it can either be used to create a three-dimensional model first to be rendered into orthographic diagrams. Alternatively, CAD can be used to draw diagrams directly, more akin to traditional hand drawing.

Reasons To Use CAD

As the features and functionality of CAD have improved, it has gradually become an essential part of modern design processes. There are a lot of reasons to consider using it:

High-Quality Diagrams: You can be confident that the diagrams produced by your CAD program will be high-quality, detailed and precise. Unlike hand drawing, you won’t make a mistake simply due to a shaky hand or a straightedge slipping.
Easier Modifications: If you need to revise your diagram, you can immediately start making changes. With hand drawing, you sometimes need to start over, depending on the extent of the necessary revisions.
Version Control: You can use version control for your drawings. Made a mistake? Simply revert back to an earlier version. Most CAD programs also have built-in undo functions for smaller reversions.
Simple Sharing: Teams can share CAD documents digitally. In some cases, they can even simultaneously collaborate.
Design Templates: Many CAD programs allow you to work from templates. If you make a lot of similar diagrams, you can make the process simpler by crafting your own template as a starting point.

Reasons To Use Manual Drafting

Despite the significant benefits of CAD programs, there are still many reasons to use drafting tables and hand drawing. These are a few of the reasons you may consider manual design:

Freer Creativity: There are fewer constrictions when designing by hand. You can be freer with your creativity. This is especially valuable for those concerned with form as well as function (such as architects).
Faster (Sometimes): For many people, drawing by hand is much faster to reach an initial design. Thus, some people use hand drawing to get their ideas down on paper before refining them in CAD.
More Connected Design Experience: Putting ink or graphite on paper can be a much more connected experience than designing with a computer. This can potentially make the design process easier, especially at the conceptual stages.
Low Cost: Relative to CAD software, manual drafting is very inexpensive. Drafting tools and supplies are fairly cheap and only require a one-time purchase in the case of the former. Even furniture such as a drafting desk is very low cost in comparison to long-term CAD license subscriptions.
Less Training Required: Learning to draw by hand takes time and training. However, this is usually less than that needed for CAD. This is partially because designing with a computer often requires some of the same drawing skills as hand drafting, plus the addition of technical skills.

Which Is Better?

Ultimately, there is no simple answer to the question of which is better. Both have benefits and drawbacks. In fact, that is likely why many professionals use a combination of manual drawing and CAD. This isn’t just the older generation that is more used to manual design. There is a lot of value in starting with hand drawing before refining the design in CAD.

This helps to explain why touchscreens, stylus pens and drawing tablets are becoming so important in modern CAD solutions. People like the experience of manual drafting with the benefits of computer-aided design. Of course, for others, having a facsimile of manual drawing using a computer can never replace the richness of putting a pencil on the page.

Ultimately, if you are designing professionally, you will likely be well-served by investing in both a good quality drawing table and a CAD solution that works for you. Being equipped for both will give you more flexibility.

You can order a drafting table any other drafting supplies from Engineer Supply. We have a large catalog of products for engineering, surveying, construction and other fields. Whenever you need high-quality equipment and supplies for your technical job, Engineer Supply has you covered.

Why Should I Buy a Drafting Desk?

Hand drawing continues to be an important part of the design process for many professionals. With a drafting table, you can more easily draw longer, straighter lines and maintain proper perspective. The angle helps to make it easy to reach the full extent of the page without needing any awkward arm positions.

Can I Fold My Drawing Table Flat?

Yes, most drawing tables can be folded flat when needed. Some are better designed for flat use than others. The best quality tables can be positioned in a variety of ways to suit the needs of your current task. Some people prefer tabletop drawing boards because they can be stored when not needed.

Should I Use a Drafting Desk?

Many drafters find that drawing on an angled surface makes it easier to maintain precision and accuracy throughout the diagram. However, it also takes a little practice to get used to using a drafting table. They are not for everyone, but chances are that if you draw a lot, you will appreciate one.

Which Are the Best Drawing Desks?

While all drawing desks perform the same basic function, some rise above the rest. The Studio Designs Vision Craft Station is a popular and affordable option. For a large-scale, dedicated drafting table, consider the Mayline Futur-Matic. A Safeco Precision is another great choice if you value space to draw.
