# Rotating Lines

In this Rhino Grasshopper Tutorial we are going to learn how to make a series of rotating lines around two circles.

Tutorial : Mohammad Yazdi

Now that we have learned how to model the rotating lines, we will talk about adding circles on the intersections.

Now we will change the algorithm so we can make the lines and circles on a horizontal line with any direction.

We will also model two boxes at the start and end of the bridge, so we can visualize our project better.

At the end we will also add the deck parametrically, so we can change the height of the deck based on our project.
