*NBBX
In some cases when STL repair is engaged, the bounding box may be slightly changed. This can interfere with the *SYMM card or mechanical constraints such as *FIXC and *FIXR, as the origin is moved. By default, after pre-processing is completed, the bounding box is reset to initial value, so cards that contain user-specified coordinates align with the coordinate system used in the FE mesh. Use *NBBX to override the bounding box reset, using the updated bounding box after part repair.
