How many times you have wondered how to make the thread of a screw with SketchUp, or not? Here is the answer!
First you draw a circle. We click on the instrument "Circle" in the toolbar and then on the point of origin of the axes and widen our circle by following one, red or green, with the cursor, so that the vertices of the segments that make up the match with aces.
Created the circle, from this, we have to create a spiral. The steps to follow are the same that you can find in the post "HOW TO CREATE A SPRING WITH SKETCHUP", would not explain them again.
Now we have a cylinder created by the initial circle and a spiral of the same diameter with the plugin "Weld" we welded into a single segment.
It 'important to create a group of one of the two models, in this case, my group is the spiral. This is to avoid that the two models, when superimposed, is intersichino between them. Then we position the spiral over the cylinder so that the segments coincide perfectly with each other.
We click on the instrument "Move" and then on the group spiral with the "CTRL" key to create a copy, spostiamola down along the blue axis until it reaches the center of the original one (see image below).
Now we can explode groups of spirals so as to intersect the segments with those of the cylinder.
We click on the spiral just created to highlight it , then the instrument "Scale" and finally, with the CTRL key pressed on the handle of the solid angle at the center, ...
... Pull outwards and ...
The screw ... is ready.
Under another example of a solid made with the same method created simply by moving the internal spiral downwards.
Or this' other using the plugin "Joint Push-Pull".

At the bottom of some steps of the modeling of the body of a Shelby, as usual, I start with a picture Blueprint and then continue to the eye.
For the reconstruction of the dashboard, I was inspired by a photo found in the network.
Some views of the finished model.
