Exporting to a Parasolid File When exporting to Parasolid text or binary format, a unit conversion can optionally be performed during export. Use the following method to select the export length unit: model.geom(<tag>).export().setLengthUnit(<unit>); where <unit> is either fromgeom to disable unit conversion or a COMSOL Multiphysics length unit, such as m for meters or in for inches.
