Finite　element　data　form　an　important　basis　for　engineers　to　undertake　analysis　and　research.　In　most　cases,　it　is　difficult　to　generate　the　internal　sections　of　finite　element　data　and　professional　operations　are　required.　To　display　the　internal　data　of　entities,　a　method　for　generating　the　arbitrary　sections　of　finite　element　data　based　on　radial　basis　function　(RBF)　interpolation　is　proposed　in　this　paper.　The　RBF　interpolation　function　is　used　to　realize　arbitrary　surface　cutting　of　the　entity,　and　the　section　can　be　generated　by　the　triangulation　of　discrete　tangent　points.　Experimental　studies　have　proved　that　the　method　is　very　convenient　for　allowing　users　to　obtain　visualization　results　for　an　arbitrary　section　through　simple　and　intuitive　interactions.　©　2018　by　the　authors.
