How to convince your audience with your sketches |Line weight

A designer needs to be good at visual communication.

In order to defend his ideas and convince his audience.  Best presentation boards are the one which doesn’t need the presence of anyone to give an explanation.

We want to be efficient, attracting, and giving a path to people’s eyes on your presentation boards.*

*It’s similar to how a graphic designer would think and prepare a packaging visual, thinking on which information the customer needs to see first.

The technique that follows is commonly used by product and transport designers. They love giving a variation of the weight of the lines to pop out there best ideas and sketch from the board.

With these simple steps, yours will instantaneously become more professional!

TIP

Whether on your research or presentation boards, use this technique on your best sketches and ideas.  “Make them pop out like a black sheep among a troop of white one.”

Weight-line

  • Get ready to draw with a light pen pressure
  • Draw a cube in perspective

Weight-line1

  • Keep the same pen pressure
  • Detail the cube by creating negative space

Weight-line3

  • Define a source of light – usually at the top left.
  • Retrace the lines of the volume with slightly heavier lines.
  • Bold the lines are opposite to the source of light – only the lines which are at the edge of a single surface.

Weight-line2

  • Add a quick and simple background with hatching

That’s all!

    Yea great tutorial, I didn’t know much of this stuff and it’s the little things that help out.

    It’s interesting to know the techniques used to make designs stand out and how to present them which I find important.

    I recently finished an ME degree but this is what I really want to do!
