It is the tough job to do technical drawing for product design manually. In order to understand more about this type of drawing we need to start it with all the classical tools. Talking about the tools we are going to see in this hub one of the best brand where you can get all the tools that you need.
Works on technical drawing require a good skills and supporting from the right tools. With good tools we can produce a good drawing with shorter period of time. There are many skills to produce the required drawing that we need but with some tools such astemplates, accurate compasses, set-squares, French curves, stencils, a gooddrawing board, and the appropriate drawing pens and pencils you can produce a better drawing with less effort.

Technical Pencils and Drawing Pens
As basic tools in drawing, the pen and pencils will produce the drawing lines for your drawing. The right pen and pencils will aid your drawing to be easily understand by others on how the drawing turn into a real product.
Basically the pencil are classified by itshardness (represented with letter ‘H’),blackness (represented with letter ‘B’) or finest (represented with letter ‘F’). The needs for various types of pencils depend on the level of the drawer usually called ‘draftsperson’, ‘draughtsman’ or ‘designer’. Usually we need four to three types of pencils even for beginner.
So what about the technical pencil?Technical pencil eliminates the sharpening process for pencil. We can always get fine tips from our pencil all the time we need it. With the various types of pencil leads same as conventional pencil the good quality of technical drawing can be produced even faster. There are more to talk about good technical pencil such as extra grip, hardness grade indicator, constant length and extra features to gain your confident.
Same as technical pencils, technical pens are graded according to its tips size. Different than the writing pen that we use for writing or sketching the sizes are 0.13, 0.18, 0.25, 0.35, 0.5, 0.7, 1.0, 1.5, and 2.0 mm. Among the brand leaders for technical pen are Rotring, Staedtler, and Koh-I-Noor that still producingtechnical pens until today. The market for technical pen was shrinking since the introducing of CAD (Computer Aided Design) design softwares.
Compass
In technical drawing, compass will be very useful not just to draw circle but also to make certain angles easily such as 90°, 60°, and 30°. Good compass will never slip during the drawing process and make your circle imperfect. In some greater models there also included with adjustment dial to help you get the accurate size of circles require. Additional features like rubber grip will give extra comfortableduring the drawing process. As I said that compass is very important in technical drawing, we better have various selections of compasses to make sure a good quality of technical drawing.
T-squares, set-squares
Other essentials tools for technical drawing are T-square and set-squares. These tools work together to draw lines and different angles (set-squares come with 60°-90°-30° and 45°-90°-45°). Set-squares will slide on T-square to create serials lines at different distance. You’ll find that using set-squares will be very helpful in technical drawing. Certain drawing standards need you make full use of set-squares to draw the guide lines for your drawing. After certain period of times you’ll find that set-squares become your favorite tool.
French Curves, Template and Stencils
French curves are use to help you to draw curves nicely. You can draw circle with compass but when it come to ellipse the usage of French curves will be very helpful in order to produce perfect curves of the ellipse. So when there are need to use some curves for your design, then French curves will always be needed.
Different from French curves, templates and stencils only additional tools for technical drawing. Anyway the usage of the tools can really save you lot of times. In some cases stencil can produce cleaner result for your design. There are many types of templates and stencils since the can range from shapes, letters and numbers.

As we can see with the advancement of computer technology today, the technical drawing totally taken by computer. The full technical drawing of complicated building design can fit into small thumb drive compare to full cabinet of drawings. What we need to keep in mind that the great technologies of today was built with the understanding of this special skills.
I miss something here! Yes, part of the tools also includes the drawing board or drawing table. Please do you research about it if you think you need to know more about the tool or maybe I can help you with my next hub.
