Hi @Bogdan_Chipara,
you might try below hack to get to the whole text, then filter out what you need:
import rhinoscriptsyntax as rs
def WhatCommand():
id = rs.GetObject("Select object", 0, True, True)
if not id: return
rs.Command("_-What _Clipboard", True)
result = rs.ClipboardText()
rs.MessageBox(result, 0, "Object Description")
WhatCommand()
@Alain, the rs.ObjectDump
method is still missing in the WIP.
c.
