About Passers

Every passer-by who has to deal with geometry knows how frustrating it is if they are not able to draw perfect circles. In some cases, an inaccurate circle can ruin the entire design. That is why it is essential to have a drawing compass that works well.

Drawing a circle does not have to be a big deal. But in reality, a lot of students and drafters go through the pain of circles that are skewed or do not end where they started. The culprit behind lopsided circles, more often than not, is a bad compass or passers. Being one of the most vital tools in a geometry set, a compass should be accurate. Therefore, instead of picking any random product that you see, you should look for the accuracy and built quality of it before buying. Read this article to know more about these measuring intruments and the factors that affect their performance. Having a better understanding of them will help you make the right choices when you shop.

Best drawing compass buying guide

If you are on the look for a good quality compass, then you might as well consider buying the best among them. However, not all products are created the same. Some are meant for students, while others are designed with professional users in mind. And for that reason, it is possible to list more than one set of drawing passers that will qualify as the best in different categories. Here is a list of the four best composes that you can consider buying. On top of that, this article will tell you all about compasses and what to look for in them.

Mr Pen geometry compass set

This is a drawing compass set with the great built quality and sleek design. But the function is more essential than form when it comes to compasses, isn’t it? Interestingly, this set fares really when even in the drawing department. This set with fifteen good looking pieces pretty much promise you perfect and precise circles. Moreover, you get two different compasses included in the set. One of them is your regular math compass. The other one is a graphic passer that can hold either pen or marker pens at the drawing tip.

Offizeus professional drafting compass

When you are drafting an architectural drawing or a design of a machine, there is no way you can compromise on the accuracy. For the circle to be accurate, the legs should not move while you are trying to plot the circle. To solve this issue, this compass comes with an adjustable centre wheel. This wheel has locks so that you can adjust the radius depending on the diameter of the circle you want to draw. Another common problem that affects accuracy is the tip of the product moving away. The non-slip tip of this passer provides an elegant and simple solution to maximise accuracy.

Maped drawing compass set

An architect’s worst enemy is a compass that does not stay in place and bends while he is trying to draw. The solution is to get a product made from rigid and durable material. A Maped compass is one of the best that you can get if you are an advanced user. Using a combination of high-quality hard plastic and metal, this instrument manages to pack accuracy and durability. That too, at an affordable price range. One aspect of a compass that people often forget to stress is ergonomics. A good passer should not just be accurate; it should also be comfortable and easy to use. Maped drawing set offers you that as well.

Mr Pen Professional drawing compass

To be honest, for a regular student, this compass is overkill. However, if you are an advanced student, a professional, or a teacher, this compass set is absolutely invaluable. From the full metal body to the adjustable locking wheel and beyond, every inch of this product is designed with professional users in mind. Included with this set, you will also get some nifty accessories as well. One notable accessory in the set is the extension beam. This will basically let you make the passer longer so that you can draw circles with larger radii.

Tips on how to buy Drawing Compass Sets

A compass is a tool that anyone who wants to create complex geometries cannot do without. But for the art and design to be perfect, you need more than just any compass. Only a great product can draw great shapes. Well, how do you buy a compatible product then? It is, in fact, easier said than done. There are more than a couple of things you should look for in a product to ensure its quality. Here are some tips that you can follow while shopping. To some extent, these tips apply to other mathematical instruments, as well.

  • Accuracy – Cheap products come with a lot of tradeoffs. One downside that is common in almost all cheap products is that they lack accuracy. Although this is okay for high school students, inaccuracy can be a real problem for professionals and college students. If accuracy is important for you, go for sturdy and large ones.
  • Adaptability – How do you want to draw with a geometrical instrument. Do you want to draw with a pen or a pencil? Or do you want a compass tip where you can attach a graphite tip? Usually, these two are of completely different kinds. Sometimes your profession might demand both of these types. In that case, there are plenty of drawing compass sets that come with both types of compasses.
  • Maximum radius – The larger the compass is the larger the circle you can draw with it. Therefore, smaller drawing compasses can seriously limit the size of the circle that you can draw. That being said, there are some accessories that will let you extend the instrument. These accessories might not necessarily make the product but will offset the drawing tool further away from the centre.
  • Built quality – Look at the built quality of the compass when you shop. A lot of it depends on what sort of material is used in the compass. It is very usual for compasses to contain both metal and plastic elements. However, make sure that the plastic joints of the compass are not brittle. You can easily do this by checking the type of plastic that is used.

If you are a professional architect or a math student, you will need other tools besides a compass set.

Question & Answer

What is the right way to use an engineering drawing compass?

Before drawing, you need to prepare the compass first. You should be really careful about the drawing instrument that you attach to it, especially if it is a pencil or a graphite tip. It should be sharp. Also, in the case of a graphite nib, it should be strong enough not to break. After setting up your instrument, it is now time for adjusting the radius. To do that, use a ruler. Using a ruler, measure the radius of the circle you want to plot. If the compass has a locking mechanism, lock it after adjusting the radius. After that, everything is easy. You just have to fix the sharp tip on the paper and plot the circle.

Is a compass necessary for geometry?

A drawing compass is probably one of the most important tools in a geometry set. It will be the tool that you will be using the most often than others. So, why is a compass so important? Well, that is because circles are important in geometry. Architects and mathematicians use circles all the time as the base to draw other shapes. Moreover, compasses can do much more than just drawing circles. In many applications, they can replace a divider or even a protractor. So, the reason why a compass is important for geometry is its versatility.

When was the drawing compass invented?

The invention of the compass has an interesting backstory. In fact, compasses were meant as a tool for the military. Calculations using these instruments helped the army to use firearms with precision and accuracy. The brain behind the first geometric compass was the famous Italian astronomer Galileo Galilei. Later, other people figured out that this tool is extremely useful in other areas as well. Therefore, they became popular among mathematicians and math students. After some time, architects and designers also started using them.
