How to model a decagon?

#1

Does anyone have any ideas? Thanks!

Like this? or do you mean a dodecahedron?… neither of these is very complicated … the first is cylinder with 10 sides… the second is a platonic solid which most modeling programs have as a default shape…

I’m modeling a 10 sided dice

#4

a ten sided die (in terms of old tabletop games) is a pentagonal trapezohedron… meaning it is slightly squashed. And to model it, I would model the top half using a hemisphere, pulling every other border vert upward slightly. Then duplicate the hemisphere to the bottom, rotate it until it fits, and then weld the seam shut.

PS: a decagon is two dimensional, a decahedron is three dimensional. If you’re not talking about the 10-sided die that I mentioned, post an image of what you’re talking about… there are several types of decahedrons, and they all look pretty different. The one I’m talking about looks like this:

i’m waiting on my machine to defrag, so i was bored and made a little tutorial image for you:

Eldee, thanks so much!

Hi eldee, i’m kind of a noob so this is a noob question: i tried to follow your tutorial, but I didn’t find the vertical SubD option in the sphere modifiers, I use 3DS, is that option in another program or i’m just looking in the wrong place? Thanks in advance.

Just create a 10 sided sphere (10 U, 1 V - So it looks like a 10 sided diamond). Remove the lower half of polygons. The half that’s left; select every other point and move them up a bit. Duplicate the mesh and rotate it 180 degrees. Align the “notches”. Weld the points together and delete every other edge. Bevel as needed…

unfortunately, in 3dsmax you can’t control the vertical and horizontal subdivisions independantly- but it’s still pretty easy to do. just create a primative sphere, and set the segments to 10. Change the Hemisphere spinner to .5, and then just delete the two remaining edgeloops that are left. the shape of the object will be the same as the one in step 1 of my little image up there.

Thank you, both of you guys. I got it.
