Ok I will eat some of my words on that one. Up until yesterday I had not down loaded the upgrade on 3.xxx or Sculptor demo. My comments were based on the info provided by CarveWright.
After doing the upgrade and working through a WTF moment of being stuck in DEMO MODE until I updated my license file this is what I have figured out. Running Sculptor as a stand alone you can export as STL to be used in any version of designer. Right? To me the STL importer would be one of the most recommended add ons to have with all of the free stl files available on the web for making new patterns for the CW.
Since I am only running Sculptor in demo I can not verify this but if one has Pattern Editor, after exporting the stl out of Sculptor and importing the stl into designer one should be able to open the new pattern with the Pattern Editor.
