Script:
In the previous video, I've shown how to draw a Hex Bolt. You can get the link to that video in the description.
In this video, we will draw its 3D model.
Let's open the drawing.

I will draw first the bolt head. The width across flats is 10 millimeters and the head height is 3.6 millimeters.
Given these dimensions, we can easily create the head bolt using presspull.
Let's draw a polygon with 6 sides and a radius of 5 millimeters, which is half the width across flats.
Later, I will use chamfer-edge, that's why I need to measure the distances of the chamfer with a 30-degree angle.
After presspull, the 3D hex bolt head can easily be made using intersect command.

For the shank and thread part of the bolt, I will copy it from the previous drawing.
Using the revolve command will speed up the process of drawing.

The number of turns is computed, by dividing the thread length and the thread pitch.
For M6 we have a pitch of 1 millimeter and I've assigned a thread length of 15 millimeters.
15 divided by 1 equals 15 turns.
To adjust the number of turns we will use properties and edit the number of turns.
