Was thinking of making a 5-sided plane and then rotating them and merging verts but that would get messy.

Ideas?

Thanks

What you want is a Dodecahedron. You can create it by going to Create>Polygon Primitives>Platonic Solids>Option Box. Set the platonic type to Dodecahedron, and click create.

yeah works ok but i wanted to turn it into a sub-d object and it doesn't seem to want to work

Of course, because Sub-D's work best with quadrilateral polygons. You would need to modify the mesh by hand to make it usable.

Use a polygon bevel.

To change to quads use the smooth mesh in mesh tab and change the continuity to 0.............dave

NextDesign has the best solution. Create a platonic solid dodecahedron and then do a poly bevel with a small offset and 2 segments. You can then render both unsmoothed and smoothed.

Rick I don't do sudDs but if you just bevel that will still leave a ngon in each face is that OK user added image

It will be all quads Dave. If you bevel with two segments it would be like manually putting a support edge on either side of the original edges with a little smoothing to boot.

The nice thing here is you don't really need to smooth afterwards and you get a very nice edges. But if you have to smooth it will work out as well and if you subd the 5-sided ngons of the main faces will be transformed into all quads.

Here is a quick video to demonstrate and you can see the corners are nicely quadrangulated....

PS - I did notice the main faces are indeed dreaded ngons (5 sides) but if you convert to subd the catmull-clark algorithm will convert them all to quads.
