How do I keep windows and doors but fill in their openings?

hi I am new to revit and was assigned the task to 3d print an architectural model with grey windows and doors. However when I import the model into the slicer software and slice the model all the windows and doors disappear and I am left with just the openings for them. Is there a way I can keep all my doors and windows and fill in the openings for them? I have attached images of what my model currently looks like in slicer software as well as an image of what I want my model to look like.

Do your slicer software read DWG or other file format?

No I am using Bambu Studio which only accepts 3MF, STL, STEP, SVG, OBJ, and AMF files. I only know how to export revit projects as STL files.

Try export as OBJ and see if that makes a difference

my windows and doors still disappear and all I'm left with are the openings. I think I need to make chances in revit, I'm just not sure how

How detailed is your door and window? Does your software have a tolerance factor that will not show any object less than what can be printed in the 3d printer?

Modify your door and window families to use a void cut the host partially, not completely.

Depending on the slicing software, very thin and small elements may be automatically discarded between the file output from Revit and the import process without any specific warnings. I suspect that this is happening in your case.

 

If it is so, you will need to modify either the Revit families (in a work copy) or post process the output file before importing into the slicer software. Depending on your 3d printer, you will different minimum dimensions for geometry. In the case of windows and door to be printed as solid, I would suggest you modify the families to add an additional thickness towards the inside of the exterior wall. 

Alternately, if you don't have many opening, you can model some in place masses on a separate workset to replace the disappearing geometry in Revit or open the model in a more straightforward modelling program and manually "thicken" the geometry. 

For my resin 3d printer, the recommended minimum thickness is 2mm for large vertical planes and 1mm for small door sized parts. Your screen capture seems to be a filament 3d printer which may have different minimum thicknesses.

Hope this helps,
