Order of points when using connector builder

[OscarPacheco]

Hello!
I am analysing one component that has pressure insid. The exterior of this component is join to a wall by one rigid link. I am trying to simulate this connection by using connector builder. It works fine, but the results vary depending on which point I select as first connection point. Which point should I select first? The one that is in the wall (not moving at all, kind of "master", or the one that is in the component that can actually move (as a slave)
See pictures of different results.

Thank you.

Quote from the Analysis Users Guide:
"The position and motion of the second node on the connector element are measured relative to the first node."

Consider also the CSYS that might or might not move or rotate in the first node. This is used for the measurement.
