Planning your engineering drawing
Before starting your engineering drawing you should plan how
you are going to make best use of the space. It is important
to think about the number of views your drawing will have
and how much space you will use of the paper.
Try to make maximum use of the available space. If a view
has lots of detail, try and make that view as large as possible.
If necessary, draw that view on a separate sheet.
If you intend to add dimensions to the drawing, remember to
leave enough space around the drawing for them to be added
Choosing the best type of paper
As mentioned above, sketching skills tend to improve if you
use large pieces of paper. Learning to sketch on A2 paper
is a very good way of gaining confidence in your skill.
But most people find A2 an inconvenient size for project work.
If you can, try to do sketches for your project on A3. Buy
a pad of layout paper. This type of paper is useful because
it is slightly opaque.
When drawing final ideas you can quickly sketch your basic
idea getting proportions correct and then use another sheet
of layout paper placed above to trace the original sketch
without mistakes and guide lines.
If you are working with inks on film, plan the order in which
you are drawing the lines. For example you don't want to have
to place your ruler on wet ink
