When TPC imports a LandXML file, TPC displays a dialog, showing the data it supports in a dialog tree. You then select the data you want to import. See LandXML Import Tree.
TPC does not support all LandXML data types, but strives to support the ones you use most often like Points, Parcels, Alignments and Surfaces. If you have a LandXML data type you need, just contact TPC technical support and let them know.
