I’ve been looking through the field drawings, and either I’m missing something or there’s a mistake in the arena manual. Section 2.2.5 says the pyramid’s angle is 68 degrees. However, both TE-13001-02 (Leg Support from the Team Drawings, page 3) and GE-13019 (Pyramid Leg Base from Game Specific Drawings, page 43) seem to say that the legs are at an angle of 60 degrees. I also checked GE-13020-02 (Gusset, page 49) and it seems to be designed for the pipe to be angled at 60 degrees. I’m just a humble programmer over here, so could someone else look at it and see what’s wrong?

I know some other’s have noticed that. It is likely due to the different construction techniques.

Check out this thread

I am not sure how much of a difference that angle will play for climbing the pyramid.

I have some time tonight so I’ll see if I can wrap my head around the difference and come up with a better answer.

I’d be inclined to believe that, but the official drawings which are supposed to be identical to the real field structures (the ones prefixed with GE) also seem to be built with 60 degree angles

In the past, Q&A has always answered that the field drawings over-rule the manual’s simplified diagrams. I would trust 60 degrees until someone has a Q&A answer.

I did some math.

Let’s start with the 4 corner poles each at a 60 degree angle.

If you measure the angle between the plane formed between two of these and the ground, you’ll find that it’s at about a 67.8 degree angle.

I think I figured it out. If you look at page 56 of game specific drawings. There is a marking for 60 degrees. 60 is the angle between the 4 corner posts, and the horizontal plane.

68 is the angle between the horizontal members and the corner posts in the plane of the side.

The angle between the horizontal plane and the corner posts is different from the angle in the plane of one of the 4 triangular sides between the horizontal bars and the corner posts.

Visual aid two pencils in an L shape tilt the vertical pencil so it is 30 degrees off the table, its angle to the horizontal plane is 30, but the angle to the other pencil in the plane they share is still 90.

ZehP did the math to go with my visual tinkering, Calc 3 has been a while…

Ah, makes sense. Thanks!

Above is correct, the 60 degree angle when viewed from side as shown in the game manaul is 67.8 per SolidWorks.
