I'm trying to export a mesh from solidworks.  I need to export both surface meshes and solid meshes.  Is .geo the best file format for this?  Looking at the .geo file, it seems like each node is listed as an (x,y,z) coordinate on lines marked ND.  It looks like the EL line lists information about the element, but I'm not quite sure how to decode it.  I'm guessing some of the numbers are node indices, but I can't figure out the rest of the numbers.  Is there information anywhere on the .geo file format and how it saves a mesh?  Alternately, is there another format I can export to with information about the file format available?  I guess I can do .stl for surface meshes, but I'm going to need solid meshes as well.  Thanks.
