$\bg_white \\1 mm = 1\times10^{-3}m\\ 1 mm^2 = 1\times10^{-6} m^2\\ 1 mm^4 = 1\times10^{-12} m^4\\1kPa = 1\times10^3Pa \\1MPa = 1\times10^6Pa\\1GPa = 1\times10^9Pa$

As for the drawing, you need to show the internal features.

I think the bolt will come out a little too?

I think I am fucked for drawing too ._.

You will always take the dimensions that they have given unless they actually specifically tell you to measure it yourself.

In this case, you know the length of the thread is 35mm but the scale is 2:1, so you will draw the length of the thread as 70.

1:2 = 1/2 (smaller)
2:1 = 2/1 (bigger)

Re: Engineering Studies Marathon

Measure the height of a to b in the front view.
Extend from b across horizontally for how long the height was.
Draw a line from a to the extended point of b to form a triangle.
The hypotenuse is the true length.
