Truncated octahedron
-
I want to create a truncated octahedron for educational purposes. By now I found this way: Start from a basic octahedron, divide the triangle lenght by 3, draw lines and then cut the pyramides of (orange part). This is quite easy but it takes some time. To show how the octahedron is transformed I would like to try it with dynamic components. I dont work with the SU pro but i consider to buy it. Is something like that possible? Perfect would be if I click on the model a part of the pyramides is cut off. That can be repeated al long as dimension x is not null. Is this the right way to do it?
Regards

You can't really do anything destructive with Dynamic Components so they wouldn't help you cut up an octahedron as you show. You could create the various polyhedrons so they occupy the same space. Put them on different layers and activate the layers one at a time to give the appearance they are being cut down. You could do that with a Dynamic Component but there's really no need since you could also do it with layers and scenes or even just layers.

Here's a quick example. I didn't add the color but it could be done to show the parts that get cut away. You could make it much more elaborate, too.

Yes, that's right. I was thinking about this way: The octahedron is always truncated. With the DC I would just change the dimension X. Sorry for missleading. Perfect would be if I could change this X by something like a slider.

Maybe you could use a Section Plane animation?

I did it like this. It works when I alter the component. Unfortunatley the whole model looks quite confusing (for students without SU experience).
When I work with sections and scenes I'am afraid I can't control the amount of truncation. I just can switch between the preset scenes, is that correct? Could I control an DC by a slider? Even a self created one which comunicates with the octahedron.

As time goes by I fixed the problem with the sections

It works now pretty good. If I worked with DC, could I control the amount of truncation without getting into the component and change the position of the section? Something like a slider would be perfect. Specially if I could control it from outside of the component. Can something be done by DCs?

Isn't there a really cool plugin that does this sort of thing? It graphs equations or something, and maybe one of the examples was similar? I'll see if I can dig it up. I just remember really having with it.

Ahh, found what I was thinking of.

D12Dozr showed an example of making a truncated sphere about 4 or 5 posts down.

OK, I'll test it.
Do you mean that I should leave DCs for this kind ob problems?
