I'm a little geometrically challenged.........what is a whatever-ahedron?

A dodecahedron is a closed 3d shape or solid made of 12 pentagons for faces. It will involve a number of steps. It is not push-a-button-and-out-comes-a-dodecahedron, if that's what you were hoping. You will need skillful manipulation of the UCS and ARRAY commands.

i believe it is a 10 or 12 sided 3d object
like a cube cubed (a pun)

anyone try to draw one? wheeeeeeeew... it's got me scratching my head.can't seem to figure out what the true length of sides will be based in relation to the cube size. I can get it to look right in an iso view, but flatten the view & my pentagons aren't flat.

Thanks, Michael. Sounds like setting UCS by object might come in handy for that project. ;)

I recently modeled something similar....a soccer ball. It has 33 sides made of pent- and hex-agons. (Some people do crosswords........) 68kb if you want to see it.

Did you see the post from GMGB this morning? I think that's exactly what they're looking for.

Draw a regular pentagon (edge to a give length).
I made this into a region for ease of manipulation.
Copy the region/face and use the align command to "align" to one edge of the first pentagon.
use the rotate 3D command to rotate the second pentagon around the edge (define the axis by the two end points) by 63°.
either do a polar array (5 items) around the centre of the first pentagon or use the align command using 3 points on further copies of the pentagon.
That should give you half the object - leave the rest to you ...........

Thank you for information, I've one question: I can't count volume of this dodecahedron, bacuase Autocad says:) that it's not region or solid, so how can i change it? m
