Frame

The next step was to create the frame for the tracks to sit on. I started out by creating a box scaling it to the height of the tracks. I then duplicated this 3 times to create the 4 corners of the frame.

I then created a box to cover the middle, scaled inner polygons to create a rim, and deleted the inner section. I then created polygons over the empty areas. I drew a line the height of the frame, and used the spacing tool to place them.

To create the diagonal bars, I used the same method of spacing and cloning to fit them. I used reference images to get as close as possible to the real thing.
