The patch worked OK for me (not great but workable). If you have MACOS you might check out Pixels3D which is giving away version 3.5 for free. It should tide-you-over until the new patch is done. It is a very powerful program with nurbs/splines/3Dsculpt/mesh/animation/shaders similar to C etc. The UI is also pretty good & it dosn't take over control of the desktop. The major drawback is that this version dosn't export in 3DS or Obj, only DXF. Oh well, can't beat the price. Check it out at: http://www.pixels.net/newweb2/support/downloads.html
