I’m trying to print from a STL export of a Revit floor plan. It looks OK in the Prepare window but fails in the slicer. Any thoughts for why? No errors reported.
It’s possible that the geometry is too small in those areas. As an experiment, maybe try cutting out just a portion of the model and scaling it up to see if it slices correctly

The walls are too thin for your nozzle and/or line width. Once you slice it, the walls will disappear for any walls that are too thin to be printed.
You can try changing the walls from classic to arachne, that’ll probably make the walls printable given your current configuration.

Use a Top view, zoom waaaaay in, and (U)se the measure tool to check the model wall thickness. Features narrower than your nozzle width will not be sliced. Try scaling the model larger, or using a smaller nozzle.

Or if you haxe a .2 nozzle try that. You can always try that in the slicer before swapping the nozzle.
