Hi, I have a question about converting XML to TIN. If the XML file is small, I can use the tool LandXML to TIN (3D Analyst Tools -> Conversion -> LandXML to TIN). However, when I have a large XML file (469 MB), the tool couldn't perform the conversion. Usually when the tool is able to read the XML file, in the box "TINs to Import (optional)" will automatically detect the name of the XML TIN variable. When the XML file is large, ArcMap failed. I wonder if someone ever had this problem before and how can I fix it? Thank you.
