  if you want to pay for plugins, sycode has many plugins for a large variety of CAD platforms.
  http://www.sycode.com/
  and there is also simlab:

  they also have a plugin to import/export in many formats, including STL, but they're not free either.
  there are such plugins available for free, and they can coexist in the same SU install, by showing up in different menus.
  I use the STL import plugin from Jim Foltz, which shows up in the file>import menu and works great.
  there is also an STL import export plugin that shows up in the plugins menu, it can be found on sketchucation http://www.sketchucation.com/ and googling for its file name leads you there as well: su2stl.rbs
  and there is one other that exports to either DXF or STL and shows up in the tools menu, but I forgot where it came from.
