Modelling exercise

I know how to do it ! (go to

for similar work)

btw, how to draw 3 triangles with 6 matches ?

Interesting concept, but far too complicated. The wheel consists only of straight extrusions.

Hi Heikki A nice illusion. I like it .I have sent you a copy . I wander what is the extra body you have got.

I created a very large assembly of a city and then wrote several vba scripts to animate different subassemblys. It all runs on a very large network.

Here is a screenshot of the model:

I can draw 4, does it count?

Did it. See

I had more problems with the "central" small cube than with the rest of the structure... There must be a simpler way... I''ll try to make it the "Escher" way now.

Cool, you made it almost as David Peer did. Mine was a bit more complicated, I can send you my version.

I tried as well, but the result didn't seem as natural, since SW doesn't render the silhouette edges of the sweeps very accurately. Besides, the shading and possible textures reveal that the spokes are not straight.

Sure ;-) my mistake... I meant 4 of course...

made a new, even simpler model with "straight" and "Escher" configurations Check

there's even an anim of the thing rotating. Shading with wood structures is ok, spokes look straight...

The new model uses a "body copy/move" feature to orient the central cube instead of a bunch of construction planes. looks simple, BUT I couldn't figure how the 3 angles are defined. Reached a fair approximation, but if anyone knows how to calculate the 3 angles exactly, the math side of my brain could sleep better this night.

Are you aware of any copyright / IP related to this shape ?

finally a solution ! ;-) now what about 4 triangles with 6 matches ?

Think of the 6 edges of a pyramid: they form 4 triangles
