I'm trying to print an architectural model of a house with 2 floors and a room on the roof. It was designed in SketchUp by a friend. I removed inner walls and floors to print it upside down to get just the outer look of that building. All is good in SketchUp and in Meshlab (converted
.3ds) and even after exporting it to
.stl format. But when I slice it and select preview, it is adding a floor on its own. Please take a look at the attached screenshots to get a better idea of what I am referring to. Any idea what's causing this and how it can be solved?
(Using Ultimaker Cura 4.1.0 for slicing at 0.2 mm layer height)
