OK,
so i am trying to export from revit to sketchup to make a stl file for 3d printing.
(student version hasnt have the option to do it from revit)
i go to 3d view, hide what i dont need to be export, export it to autocad 2013 dwg, open sketchup and importing the dwg file that i exported, and my component walls that i created has not show up as solid wall.
(the component wall is curved and in different angels - not 90 degrees to the ground.
i am not sure if the problem is in revit or the sketchup isnt understand the wall well.
thanks for helping
