Does solidworks has restriction on number of surfaces while opening a stl file as a solid body?

Does solidworks has restriction on number of surfaces while opening a stl file as a solid body?

I am trying to edit a human hand scan in Solidworks(like slicing, adding/removing some part), but it says Stl file has too many surfaces.

Is there any other way to do the editing to stl file?
