How to model Wembley Arena Arch

Hi all, I am currently trying to model the Wembley stadium Arch truss structure. I have played around for a couple of hours but I can’t seem to get the structure I want.

I’ve tried using Curviloft and follow line function to design the circular profile however I am having no luck.

Please find my progress and the model that I hope to produce.

Thanks all!


this is what I would like

First thought but haven’t tested it yet: I might try Helix along curve to draw bulk of it. Then maybe Path Copy to place the rings joining the helical bits.

Or maybe draw it straight and use Shape Bender or True Bend to bend it.

You could start like this, using TrueBend plugin:

When it’s just cylinder, you could create diagonals and then use Lattice Maker.

Here’s how I did it:

  1. Radial component array (2 unique components)

  2. Wireframe

  3. Follow-me & push/pull

  4. Render

Thank you!

how would you incline this to say 68’ and can you use the same process to make more of an arc than a semi circle? so say more like 140m (straight line distance from end to end) and 50m high.

Hi Mihai,

Thank you for your help

Sorry i’m new to sketchup, sure how you would make the diagonals.

so inclined like this but 140m wide and 50m tall

One way

You could use FredoScale.

To make it the right dimensions, you’ll probably have to draw it from scratch. And if you want it to be an accurate elliptical truss, then you’ll need a better method. Notice how the ends are a bit stretched.

If all else fails, you could buy a model off of Turbosquid…

But if you want exact measure, you could use ShapeBender plugin:


that drawing will looks very good, I’ve tried using Freddo scale but had no luck, would you mind sending me that? is the span 140m?

Many thanks!

It’s wise to post such requests over here…

tried to do this but got lost on the array part

You must be patient and careful when drawing those diagonals.

Then you create the two spirals and copy them by rotation.
