Paper sizeEngineer's scaleArchitect's scaleand Metric scale The size of drawings reflects the materials available and the size that is convenient to transport — rolled up or folded, laid out on a table, or pinned up on a wall. The draughting process may impose limitations on the size that is realistically workable. Sizes are determined by a consistent paper size system, according to local usage.
But, just knowing that. What does it tell us about the object or structure it represents? Technical drawing relies on a number of agreed assumptions: Of course it all becomes easier to interpret if this is added. The most important missing are scale and measurement.
Here below is the same drawing. Now it is clear what size we are dealing with. We could get all the measurements if we scaled up the drawing 10 times the scale given is 1: Notice how the longer, overall measurements are kept a little separate to make them easier to find and notice how heights and lengths are not needlessly repeated.
We now also have important written information. All this, and sometimes more, is necessary to keep track of what might become a large batch of drawings within a single project. But what is represented here is a very simple form which assumes no significant surface detail. When the designer intends an appearance which directly affects the construction of it, this information must also be on the drawing.
I also had to draw all visible sides first in scale just to work out how standard bricks could be laid in the pattern I wanted. This illustrates yet another fundamental. This is a more sensible method, because these pointers not only indicate the direction of view but also where the point or rather the plane of view is in terms of distance.
The identification and linking of parts of the drawing by means of letters and symbols is known as coding. Notice also how the measurement lines are now arranged.
When the drawing is copied it indicates that the whole drawing has been copied, i. The special language of conventions has been developed to assist and it is expected to be used. This reduces the amount of mental visualization we need to employ when trying to understand three-dimensional space from a two-dimensional drawing, but it will always involve some!

Some of the most common e-mails I get are the ones asking which materials I use and would recommend. ‘What makes a great Technical Drawing?’ I think all of the points made so far are great.
Hard to say anything different. In the end, the technical drawing should be easy to understand and easy to read. Paul Munford. 6 years ago. Reply ‘Easy to understand and easy to read’ – Got it Edwin. Good points.
Technical Drawing template for presentation is laid out in a way that simplifies the complexities you may have previously encountered with Keynote or PowerPoint. It is easy to follow, and it comes with all the design features you need built right in. Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed.
Technical drawing is essential for communicating ideas in industry and engineering.
