Hello, Mostapha! I can not understand what I’m doing wrong. I just installed the plugin and opened all the sample files from this topic. And… nothing happens, no warnings but all results is “null”. I’ve got Rhino Version 5 SR14 and Grasshopper 0.9.0076
You should share a screenshot and the the output from readMe? Does it start to read the file?
What will happen if you remove _zoneNames input? Most likely your input name doesn’t exactly match the names in XML file.
