importing

Hi

I am importing an object from an external program into solidworks.I receive an error that says "model exceeds dimensional limits Usecorrects units or scaling in options menu" I have tried just aboutevery unit. The object I am importing was surface created frommicro CT scans. The object is only 5mm in diameter and has circularcracks on the surface that are about 10^-4 m. Could the errorindicate that the model is too big or too small? I have thisproblem importing as a surface. When I import as a body I get nofigure at all or could it be that it is just too small and needs tobe scaled up? I have tried nanometers and microns for unitsalso.SolidworksImport export
