CAD Model Features

In this challenge i did not get past the first page. Making the shapes and figures are quite easy, but getting it to the right spot or coordinates was the tough part. I managed that make the circle, square, and triangle and extruded all of them. I also made the start, but i had to get it in the right position and extrude it. The most challenging part was getting the shapes in the right coordinates, but the easiest part was creating each shape. I still find getting shapes symmetrical quite hard and i would like to learn more about it.
