Basically I am asking what was already asked a year ago in this thread: Create a rounded wireframe?
The question is basically unresolved an I thought that since a year ago someone might have an answer, or simply an idea about how should I go about doing this in my own case. The wireframe + subsurf technique, even with with a crease of 1.0, will create uneven thickness with pointy corners at the vertices, however much I play with the options, and also subsurf adds unnecessary edge loops, subdividing edges between vertices.
What I feel would solve the problem is a RESOLUTION option in the wireframe modifier in order to turn those 4-sided wire frames into cylinders. Just like the option you have with curves. I know you can convert the mesh to curve but that automatically results in disconnected topology. And the skin modifier is way too heavy and results in twisted topology as well as rounded intersections.
In more practical terms, here is what I want to achieve. I have this mesh you can see in the picture above, which is actually a floor. Everywhere you see edges, I would like to turn them into cylinders in order to make a nice pattern onto what is an otherwise quite boring floor. I could of course use a texture but I would like the pattern to be 3 dimensional, and a 4-sided wireframe just doesn't make it. It needs to be round. What would be the most efficient way to do this, without the ugly results of the wireframe+subsurf, skin, or curves?
