Searching for a LISP Specialist

Searching for a LISP Specialist! I have a Polyface Mesh exported from Voxler 4 (Golden Software) which contains colors (DXF file attached). When I use EXPLODE or XPLODE commands in AutoCAD 2016 it breaks the mesh into 3D Faces but does NOT retain original colors. So, I need a LISP code that would break the Polyface Mesh into 3D Face primitives and retain original colors.
