Modifiers stop showing up as blocks in the 3D view.
A slicer project can carry geometry that never gets printed: modifier volumes that change settings inside a region, negative parts, support blockers and enforcers. They were being drawn like anything else, so a model appeared surrounded by large cubes and shrunk into a corner, while its card looked perfectly normal because that picture comes from the slicer's own render.
Anything not marked as a normal part is left out now. On a real file that removed three twelve faced cubes and pulled the bounding box in from 124 x 124 x 48 mm to 117 x 109 x 34, which is the model on its own. The smaller box matters as much as the missing blocks, since the framing is worked out from it: the model fills the view instead of being sized to fit something that was never going to print.
