I drew up two Plexi doors in solidworks.  one door I drew up in 2007 and converted it into 2009. the other I drew up in 2009.  The door that was drawn up in 2009 will work in my sigmanest 8.1 the other door does not.  there is only one other difference between the two doors. the one in 2007 i canged the plane of the first sketch from front to top.  Both doors have two dados on the left and right side.  My question is what would  be the reason one will work and the other will not?

Hope someone can help.
