Completely lost on how to create this orb

Mra

Hi there,

A bit of a challenge, how would one create this in SketchUp?

As you can see the light is made up of one or two components that is instanced around. My questions is obviously how would one be able to do this and line up all these components?

I can't label this type of geometry to even begin finding out how to start. Thanks!

That looks like it may be a geodesic structure. I'd take a look at Taffgoch's collection in the 3D warehouse for some ideas.

I think that the main problem with those kind of lamp is that the elements are not coplanar, but are kinda twisted each other. See David Trubridge designs for example.

Seems to be just two tessellations making up all the components of the lamp. I would use Tool on Surface to a sphere to create the initial curved components then copy as an array around the sphere. At this point you could also add the twisted ends so they overlap) Here you could move the components over each other so they aren't co planar and then add the little rivets. It's quite simple if you break it down but tricky in execution.

Make a Geodesic sphere.
MultipleFaceOffset.
Erase all faces with <=4 edges...
JointPushPull.
Use Artisan to sub-divide/smooth it...

Choose the 'sphere' type that gives the 'hole pattern' desired...
Here's one I threw together is a minute or two...

Nice, TIG. I kept working along those lines myself but it would either crash the computer or look like crap... I will be interested to use exactly the steps you have. I perhaps made the mistake to create my first sphere with Artisan. And I used Lattice maker. I wonder if some creasing will give sharp edged cut-outs?

TIG

LatticeMaker makes the parts as ovelapping frames which can't be easily made solid - even with SolidSolver.
Windowizer4 has similar limitations.

Here's my workflow.
Make a Geodesic sphere == I used that plugin, octahedron, 2 iterations, 1m radius.
Edited the 6 small 'sqaures' into one face...
MultipleFaceOffset == I used that plugin, 50mm offset.
Erase all faces with <=4 edges... I selected all inside the group and wrote a one-liner in the Ruby Console:
Sketchup.active_model.selection.each{|e|e.erase! if e.is_a?(Sketchup::Face)&&e.edges.length<=4}
JointPushPull == used that with 50mm offset and keeping original faces, no partitions. Makes result as a 'solid'...
Oriented the faces...
Used Artisan to sub-divide/smooth it...

It's basically this shape(roughly, I haven't rounded all the corners) UV wrapped around around a sphere. The problem is its 5 sided. Any way to do that?

TIG

That's why it's best to start with some kind of Geodesic sphere...
Mapping an image onto a sphere is going to give you brain-ache...

Here's an attempt. I started with a geodesic sphere from the warehouse. I don't have time to go through the steps, but I remade it with components. The model is attached if you want to explore the parts. It's not perfect and might not even be accurate, but it was a fun experiment. Hope it helps.

Wow, thank you so much for the amazing responses everyone. All these techniques are such good ideas, I'll try and build this myself using the different methods mentioned above as well to learn more complex items in SketchUp!

Much appreciated!
