How to thicken a surface from a SubD mesh

Hi,
I used SubD modeling to create a mesh that has zero thickness with the intention of converting it to a NURBs surface and then thickening it to a solid.
The mesh to surface conversion went well but the thickening of the resulting surface failed.
The attached image shows the mesh I worked with at SubD level 1. Before converting it to a surface I went to level 4.
Since I need to create organic shaped flat ribbon shapes, I am assuming that starting with a zero thickness SubD mesh then converting it to a surface then thickening it would be the best way.
Am I right?
Or is there a way to "thicken" a zero thickness SubD mesh and then convert it directly to a solid?
I am using Shark FX v9 with Power Pack Pro.
Thanks.

Hi Mark
Can you post the subd file? I 'll use your exact file.

Tim,
The file is attached.
A few minutes ago I discovered that I could thicken the surface created from a nurbed level 2 mesh.
Until then, I'd been trying to do it with a level 4 mesh (as in the attached file).

Something else interesting to explore when creating open surfaces, is to crease the corner vertices.

It is very interesting, but how do you crease the open vertices. Tim? I've opened your attached sfx file but I still don't know how to do it. BTW - why did thickening work on the surface created from the level 2 mesh but not from level 4 mesh? Is the surface quality from a level 2 mesh going to be as good as that from a level 4 mesh?

I suspect it is the rounded corners created by subdividing the mesh that are causing problems with thickening surfaces derived from the mesh.
I trimmed the surface so that the corners are square and not rounded - see the attached image.
The resulting surface was thickened without a problem.
I think that creasing the open vertices in the mesh would also produce good results.
The question is:: how do you crease open vertices, as shown in Tim's example?
If Tim or anyone else would share how that's done, I'd appreciate it.
Mark
