Hi Michael,

Well, I am editing this post a lot. I managed to get the Delete key to work properly.
One line prevented "moi.geometryDatabase.removeObjects( airFoilProfile );" from working in the cleanup.

The culprit is: Cancel ( ControlPointsfactories ); occuring before the removeObjects line.
Do not know why... It contains points. The other 3 factories arrays contain curves. They CAN occur before the
removeObjects line.
