Ok. Another clue (slightly blushing that I didn't notice this before..). I focus on the Position.GetComponents(...) for the moment. Recall that this should set the orientation (9 values) and the position (3 values) by means of an array passed in by reference.
To my surprise, it returns the same numbers as I put in. So, the following is happening in the terminal: >>> l = range(12) >>> res = p1.Position.GetComponents(l) >>> print res (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11) The values though are incorrect, I also tried with floats, but the result is the same. I get back an exact copy of what I put in. Regarding the workaround, can I mix comtypes and win32com? So, can I only (try) to use comtypes to let this call succeed? All other calls I have tried work flawlessly with win32com. Thanks for the effort! Much appreciated.
