I need to draw this in orthograhpic views. I'm a bit confused about the weight of lines I should use to draw. Like ,for the pat (I pointed the arrow at) you can see it's sticking out a bit, would I use just a regular weight line or what?
Also. We've been given some dimensions like 30mm and 70mm. And the thing also says the drawings need to be done on a 1:1 scale. What does this mean? DOes this mean I need to draw exactly at 30mm and 70mm, not make it bigger ration?
