Solidwork to Rhino grasshopper

Hi

Recently, I encountered the problem of importing the graph form solidworks
I have drafted a shoe model for solidwork and I want to build the lattice structure based on this geometry.
The plug-in which is intralattice seem to read NUBRUS data.
However, when I import the data, Rhino indicated the surface was trimmed surface.
How can I make the surface become the surface which can be identified by intralattice.

Thanks
