The diagonal cuts for the gable ends were all snapped out on the slab, where workers are cutting the 3-d panels, the complete gable end for both garage ends was snapped in one color red and the other gable end in another color.

The 3-D panels here were cut in front of where they stand and placed over the #4 rebar, it is always best to start at a corner as shown in this photo.

The 3-D panel being worked on is the piece which goes between the two garage doors on the front gable end, look closely and you can see the red chalk line of where the pieces were cut out for the garage doors, the workers on the top of the 3-D panels are cutting the apex or point of the top of the gable end.

This is a close up of workers Jonny and Julio cutting apex or point of gable end of the 3-D panel.
