Many times, I need to subdivide a matrix of verts in only one direction...
For example: I have a surface made of 15 pairs of verts, and I need an isoparm in the middle of those verts. If I select the 30 verts and subdivide, I get a total of 82 verts, when I only want 45 verts. Instead, I have to select each pair and subdivide them.
It would be very helpful in this situation (and many others!) to be able to select a series of verts, and then do a "Controlled Subdivide" where I can feed in a U/V count like "1,0" and Blender uses these parameters to determine the number of subdivisions in each direction.
In this way one could insert a plane, and with one action, turn it into a 8x20 vertex mesh.
While we're at it, The subdivide always makes triangle faces, which often messes up a complicated mesh. Can the subdivide feature eventually be rewritten to preserve the face/vertex count of the original face, or am I dreaming here?
there is the beauty subdivide function which subdivides along the shorter sides of a face (press the beauty button in the edit buttons, then subdivide)
also the lim below remove doubles effects the beauty subdivide functions.
That said, it would be good to be able to subdivide faces in a particular direction, and/or different amounts in different directions. How would you implement it? A "special subdivide" option in the specials menu?
I didn't now about the Beauty command, but it's a little short of features.
Maybe this Beauty is a good place (with an improvement) for especial subdivide features (par or impar stuff with x, y, z options).
