Embarassed
I have been a member of shapeways facebook and have had this account a year or so, and I still don't know how to "do" stuff.

I think I am visually challenged. Is there a useful place to start if I just want to learn to build very simple 3d shapes (geometries, cubes, structures).
I am hoping to one day build my own Genesa Crystals out of wire, until I have a collection. Of course if someone else can build one I would gladly buy it. Razz

Where should I start? I am pretty lost when it comes to math and equations. Please be nice. I love this place and I love looking at other creations....amazing stuff Shocked

peace

For simple geometry start with sketchup or 123D. There's even 3Dtin which is all online, no software to download. And they are all free to use.

I've played with all three. It's as easy as can be. Sketchup and 123D it's draw and pull. And 3Dtin is like playing with legos.

I tried google sketchup last night but could not manage it. there is a fear factor in using new software for me. I guess i am a dummy. Crying or Very Sad This is what I am trying to make.

It's a little hard to tell the angles from the image, but I'm uploading a model now. I'll post the link when it's available.

thanks for all of your time with this. if you think i should, I might also post this on the commission board. maybe someone wants to make a few extra $$ unless this is an impossible object... Confused

Not impossible, and you can do that if you want. I've already modeled it and uploaded it. Looks like there may be an issue with uploads today as it's still not in my models.

I finally got it working. http://www.shapeways.com/model/446314/torus_sphere.html?key= 695b34ab8117fabdb6deb3eb69abebff
I don't want to infringe on any copyrights so it's just called torus sphere.

that is a great model, but something is slightly off in that it is not fully centered. is the measurement even with all sides? I am sorry if I am not conveying this carefully. when i rotate this the image does not retain symmetry. i will look for the the precise measurements when i get back...

thank you for your work

I think I did have an angle off, I think I fixed it. Here's an image from my software, I tried to line it up like the image you uploaded.

I don't think that any two of the rings should ever meet at 90 degrees:

So the 90 degree should be there? It's hard to tell with the images.

Embarassed this is the thing, and this is why i am leaving this to the more proficient designers than me, because i just do not know. the whole thing is mathematical, and if the geometry does not add up the design does not work. So i don't know which the angle should be, except it should be even and add up to a symmetry...i need a math genius for this one LOL

I did some research. It's derived from a cuboctahedron. So now I have it right.

The angle of the planes where the tori lie should be the same angles as the tetrahedron http://en.wikipedia.org/wiki/Tetrahedron
So there is one horizontal torus, then you add a second one that make a 70.5288° (angle between 2 faces in the wiki page) relatively to any axis on the horizontal plane (say x or y) and finally you duplicate it twice, each time tuning it from 120° relatively to the z axis.
This should work.


So many things to design, so little time...

What overall size did you want, and the size of the torus or bands?
The one in the screenshot is 100mm and the bands are 7.5 x 1 mm

There is no harm whatsoever in having a "group" project going on here. It's perfectly valid to have "closed" projects where you and a single designer particpate offline, but it's also perfectly valid to have "open" projects where multiple people particpate in getting a design worked out collaboratively. There is room here in the forum for both types of activity.

thanks it is no problem. i am trying to decide right now. this seems to be a hard design so i guess it better to have a bunch of hands working on it

It is not really a hard design, it just looks it.
If you understand the x y z axis, I will try to explain the principle.
Draw a circle in the x y plane
Change view to x z plane, change axis to suit making it a new x y plane.
Copy the circle already drawn in the same place which now looks like a straight line.
Rotate this new circle 70.5288°. from the origin, which is the center of the circle.
Go back to original view with original x y plane.
Pick the new circle which looks like an oval, and either make an array with three copies or copy in place and rotate the new circle 60 degrees twice.
This will give you a line drawing in 3D
index.php?t=getfile&id=13720&private=0
Depending on what software you are using and what type of band you require, you can now create the profile of the band. In sketchup it is the 'followme' command.
This band could have been created with the first circle.
Hope you understand this.

I think I have it worked out thanks to 'Magic' with the correct angle of 70.5288°

i don't understand everything that you have said, but when you plot this out in 3d or as a solid, it seems to change the image in ways that it is no longer perfectly symmetrical. all i know is that the math has to be precise or the thing will not "work" as a design or with practical functions. How would your fine sketch look animated?

thanks for the time Razz Razz

that there in your collection
is a version with "flat" rings instead of the tubes. That may make for a different and more interesting construction of the genesa crystal. i have seen both.

i enjoy your shop, especially some of the religious and metaphysical objects. i would like to see how these "look" after composition.

Please see updated flat Genesa Crystal and new round shape.
You didn't answer my question about what size you require.

It depends on what material you want, and what you are prepared to pay. I will offer both models for sale at the current sizes to give you an idea on price. Then if you want the model resized I can do that. Please see link
